9 Best Real-Time Analytics Platforms in 2026: Tested, Compared, and Ranked
The most comprehensive real-time analytics comparison in 2026. 9 platforms tested — PostHog, GA4, Plausible, Mixpanel, Amplitude, Fathom, Matomo, Vercel Analytics, and Microsoft Clarity — with honest pros and cons, real pricing, and a framework for choosing the right one.
Victor Ogonyo"How many people are on my site right now? What page are they on? Which feature just fired three seconds ago?"
If you've ever shipped a major feature, launched on Hacker News, or run a flash sale — you know the feeling. You want a live dashboard. Not data from six hours ago. Right now.
Real-time analytics platforms deliver that. But not all of them deliver it equally. Some show you a live user count. Others let you click through to see which specific customer is on your pricing page, watch a replay of their session, and set an alert if that pattern stops.
We tested 9 real-time analytics platforms across actual product launches and marketing campaigns — not just demos. This guide is the comparison we wanted to find but couldn't.
What "Real-Time" Actually Means (and Why It Varies)
Before the list: the word "real-time" is used loosely. Here's what each actually means in practice:
| Latency | What it means | Tools that use it |
|---|---|---|
| < 5 seconds | True real-time. A user lands on your page and you see it appear in the dashboard within seconds. | PostHog, Plausible, Fathom, Vercel Analytics |
| < 30 seconds | Near real-time. Short enough for live monitoring, but you'll notice the lag during a launch. | GA4 Realtime report, Cloudflare Analytics |
| 1–5 minutes | Streaming delayed. Fine for dashboards, unsuitable for war rooms. | Amplitude, most Mixpanel reports |
| Batch (hours) | Historical only. Used for deep analysis, not live monitoring. | Most BI tools, Redshift dashboards |
The tools in this guide all offer < 30-second refresh at minimum for their real-time views. Anything slower isn't a real-time analytics platform — it's a reporting tool.

What to Look for in a Real-Time Analytics Platform
Minimum requirements
Every real-time analytics platform worth using should have:
- Live dashboard of active users, current pages, and top referrers
- Auto-refreshing data (ideally every 5 seconds or less)
- Geographic breakdown of current visitors
- Device and browser breakdown
- A real-time event stream or activity feed
What separates good from great
The best platforms go substantially further:
- Identified users — see which specific customer (by email or ID) is on your pricing page right now, not just an anonymous session
- Session replay integration — click on a live or recent user and watch their session
- Queryable historical data — the spike you saw during your launch is still answerable next week via SQL or a query builder
- Alerts on live metrics — get pinged when traffic spikes, signups stall, or error rates jump
- Bot traffic detection — in 2026, a meaningful portion of your "traffic" is AI crawlers; some tools now distinguish these
- Sub-5-second latency — the difference between "watching live" and "watching delayed" matters when something goes wrong
The 9 Best Real-Time Analytics Platforms
1. PostHog
→ posthog.com | Free up to 1M events/month, then usage-based
Best for: Developers and product teams who want a live view that's connected to everything else
PostHog's real-time dashboard shows who's on your site right now — with identified users, meaning you can see specific customers by email, not just anonymous session counts. Pages they're on, referrer sources, country, device — all updating live. The dashboard also surfaces a live event stream: every custom event your SDK fires appears in the feed within a few seconds.
What makes PostHog distinct is that the same data powering the live view is also used across the rest of the platform: product analytics, session replay, feature flags, A/B experiments, error tracking, and LLM observability. When you're watching a launch spike, you can click a live user directly into their session replay. If error tracking fires mid-deploy, you can see which users were affected, watch their sessions, and ship a fix behind a feature flag — without switching tools.
In 2026, PostHog also added bot analytics: a real-time view of which AI crawlers (GPT-Bot, ClaudeBot, PerplexityBot, etc.) are hitting your site, which pages they're indexing, and how LLM-referred traffic translates into visits. Useful when "who's on my site right now" increasingly includes agents alongside humans.
The underlying data is queryable via native SQL, so the "what happened during the launch spike" question is always answerable retroactively.
Real-time features:
- Live dashboard with active users, pages, referrers, countries, devices
- Identified users (see customer email/ID live, not just anonymous)
- Live event stream (custom events appear within ~3 seconds)
- Session replay accessible from any live or recent user
- Bot analytics: real-time AI crawler tracking
- Alerts on metric changes
Pricing:
| Tier | Price | Included |
|---|---|---|
| Free | $0/mo | 1M events, 5K session replays, 1M feature flag requests |
| Paid | Usage-based | ~$0.00005/event above free tier |
| Billing cap | Configurable | Set a hard monthly spend limit |
Pros:
- Identified users in the live view (rare among competitors)
- All platform data (analytics, flags, replay, errors) connected to the same events
- SQL access to all data
- Generous free tier (1M events/month)
- Self-hostable or EU cloud
- Open source
Cons:
- Real-time dashboard was in alpha as of early 2026 — not yet feature-complete vs. GA4
- The full platform has a learning curve; it's not a simple web analytics tool
- Usage-based pricing can surprise teams with high event volumes
PostHog is best for: Developers and product teams who want a live view of identified users connected to session replay, feature flags, and product analytics — and who are building the kind of product that needs all of those tools eventually.
2. Google Analytics 4
→ analytics.google.com | Free (with limits) / GA4 360 from ~$50K/year
Best for: Teams already in the Google ecosystem who need a free baseline
GA4 is the most widely deployed analytics tool on the web — which means its Realtime report is probably the most-used live dashboard that exists. It shows active users in the last 30 minutes (and, since 2024, a 5-minute window too), top active pages, traffic sources, events by type, and a world map of where current visitors are.
You can click into a random active user and see a timeline of their events in the current session. The data refreshes every 5 minutes in the Realtime report — faster than GA4's standard reports, but noticeably slower than purpose-built real-time tools.
The fundamental constraint of GA4 is that you cannot see identified users. Every live user is anonymous. If someone from your biggest enterprise prospect lands on your pricing page right now, GA4 shows you a session — not a name or company.
GA4 also requires cookie consent banners in most EU jurisdictions. A meaningful chunk of traffic — typically 20–40% depending on your audience and region — is never measured because users decline consent. This isn't unique to GA4, but it's a harder problem to solve here than with cookieless alternatives.
The interface has a steep learning curve compared to Universal Analytics, and the Realtime report is a fixed, non-customizable view. You can't filter it by audience segment or add custom dimensions to the live dashboard.
Real-time features:
- Active users in last 30 minutes and last 5 minutes
- Top pages, events, and conversions in real time
- Geographic breakdown (world map)
- Single-user event timeline (anonymous)
- Data refreshes every ~5 minutes in Realtime report
Pricing:
| Plan | Price | Notes |
|---|---|---|
| Standard | Free | Unlimited hits, but data sampling above 10M events |
| GA4 360 | ~$50K+/year | No sampling, BigQuery export, higher limits |
Pros:
- Completely free for most use cases
- Nearly universally supported — vast ecosystem of docs, plugins, agencies
- Tight integration with Google Ads and the broader Google marketing stack
- Event-based model is flexible for custom tracking
Cons:
- No identified users in the live view — everyone is anonymous
- Requires cookie consent (and loses 20–40% of traffic in many EU markets)
- Realtime report is not customizable
- Interface complexity is widely criticized
- Data sampling on high-traffic properties in the free tier
- Legality challenged in several European countries
GA4 is best for: Teams that need a free baseline, are already invested in Google Ads, and primarily care about marketing metrics rather than identified product users.
3. Plausible Analytics
→ plausible.io | From $9/month (10K pageviews)
Best for: Content sites and marketing sites that want clean, cookieless live stats
Plausible is a privacy-first web analytics tool built around one principle: simplicity. The headline number at the top of every Plausible dashboard is "X current visitors," updated every few seconds. Below it is the same unified dashboard you'd see any other day — top pages, sources, countries, devices — but with live-updating numbers.
The tracking script is under 1 KB (GA4's is ~28 KB). There are no cookies by default, so no consent banner is legally required in most jurisdictions (though requirements vary — always check for your specific situation). The dashboard is designed to be readable in under 60 seconds, shareable with a public link, and embeddable on a wall display.
What Plausible is not: a product analytics tool. You can track custom events and conversion goals, but there's no funnel analysis, no cohort tracking, no identified users, and no session replay. If your use case is "what's happening on my marketing site," Plausible is excellent. If it's "which of my logged-in customers is currently active," Plausible can't help.
Plausible is open source and self-hostable via Docker.
Real-time features:
- Current visitor count (live, < 5s refresh)
- Live top pages, sources, countries, devices
- Goal completions in real time
- Shareable public dashboard (real-time visible to anyone with the link)
- TV mode for office displays
Pricing:
| Plan | Price | Pageviews |
|---|---|---|
| Starter | $9/mo | Up to 10K |
| Growth | $19/mo | Up to 100K |
| Business | $59/mo | Up to 1M |
| Enterprise | Custom | 1M+ |
All plans include unlimited websites, team members, data retention, and a 30-day free trial. Self-hosted is free.
Pros:
- Cleanest, most readable dashboard of any tool in this list
- Cookieless by default — no consent banner required in most cases
- Ultra-lightweight script (< 1 KB vs. GA4's ~28 KB)
- Open source and self-hostable
- Shareable live dashboards out of the box
Cons:
- No identified users
- No session replay or heatmaps
- No funnel analysis or cohort tracking
- Can't see individual visitor sessions
- Limited to web analytics — not suitable for mobile apps or server-side events
Plausible is best for: Content publishers, marketing sites, and small SaaS teams that want a clean live dashboard without cookies, consent banners, or the complexity of GA4.
4. Fathom Analytics
→ usefathom.com | From $15/month (100K pageviews)
Best for: Privacy-focused teams and agencies who want Plausible's simplicity with lifetime data retention
Fathom is Plausible's nearest competitor: another privacy-first, cookieless, single-page web analytics tool with a live visitor count prominently displayed. The philosophy is nearly identical — minimal tracking, GDPR/CCPA/PECR compliant by default, fast script, clean dashboard.
The differentiators are specific:
Data retention: Fathom includes unlimited data retention on every plan. Plausible limits retention on lower tiers. If you care about comparing this October to October 2023, Fathom's retention advantage matters.
Pricing: Fathom is slightly cheaper at the same pageview tier ($15/month for 100K vs. Plausible's $19/month for the same). The gap widens on higher plans.
Ad blocker bypass: Fathom pioneered using custom domains (your own subdomain as the tracking endpoint) to route around ad blockers. This closes the measurement gap that Plausible users often experience, though uBlock Origin and similar advanced blockers have since added countermeasures.
SaaS-only: Unlike Plausible, Fathom has no self-host option. Your data lives on Fathom's servers.
Like Plausible, Fathom is a web analytics tool only. No identified users, no session replay, no funnels.
Real-time features:
- Current visitor count (< 5s refresh)
- Live top pages, referrers, countries, devices
- Goal completions in real time
- Embeddable shareable dashboards
Pricing:
| Plan | Price | Pageviews |
|---|---|---|
| Starter | $15/mo | Up to 100K |
| Growth | $25/mo | Up to 200K |
| Business | $45/mo | Up to 500K |
| Enterprise | Custom | 500K+ |
All plans include unlimited websites, team members, and data retention.
Pros:
- Unlimited data retention on every plan
- Slightly cheaper than Plausible at the same pageview tier
- Privacy-first with strong compliance credentials
- Custom domain tracking reduces measurement gaps from ad blockers
Cons:
- No self-host option (SaaS only)
- No identified users, session replay, or funnels
- Same depth limitations as Plausible — web analytics only
- Smaller community and ecosystem than GA4 or Plausible
Fathom is best for: Privacy-conscious teams, agencies managing multiple client sites, and solo founders who want forever data retention and don't need self-hosting.
5. Matomo
→ matomo.org | Self-host free / Cloud from $26/month
Best for: Teams who need full data ownership, compliance control, and a feature-rich real-time view
Matomo is the veteran open-source analytics platform — the most direct self-hosted alternative to Google Analytics, in continuous development since 2007. Its real-time view is the most feature-complete of any tool in this list.
The Visitors → Real-time view shows a live-updating log of every visitor: location, pages visited, referrer, browser, time on site, actions in session — all updating as it happens. You can click any individual visitor and see their full session timeline in real time.
Beyond real-time, Matomo's feature set is unusually comprehensive: heatmaps, session recordings, A/B testing, form analytics, custom funnels, cohort analysis, custom dimensions, goal tracking, and a plugin ecosystem. It's often described as "self-hosted Google Analytics with all the features GA4 removed."
The trade-off is complexity. The interface shows its age and is substantially more complex than Plausible or Fathom. The tracking script is ~22 KB. Default configuration uses cookies (though a cookieless mode is available). Self-hosting is free but requires server setup, maintenance, and database management.
Matomo can be run on any PHP/MySQL server. Cloud hosting is available from $26/month but loses some of the cost advantage of self-hosting.
Real-time features:
- Live visitor log with detailed per-visitor data
- Real-time user actions, pages, referrers, locations
- Individual session drill-down in real time
- Heatmaps and session recordings (separate Behaviour module)
- Goal completions tracked live
Pricing:
| Option | Price | Notes |
|---|---|---|
| Self-hosted | Free | Requires PHP/MySQL server; core plugins free |
| Cloud On-Premises | $26/mo | 50K hits/mo; fully managed |
| Cloud Business | $60/mo | 250K hits/mo |
| Cloud Enterprise | Custom | Dedicated infrastructure |
Pros:
- Most feature-complete real-time view in this comparison
- Full data ownership when self-hosted
- Strongest compliance posture (GDPR/HIPAA/CCPA) with self-hosting
- Heatmaps, session recordings, A/B testing included
- Cookieless mode available
- Plugin ecosystem extends functionality
Cons:
- Interface is complex and dated compared to modern alternatives
- Self-hosting requires technical setup and ongoing maintenance
- Tracking script is larger than privacy-focused alternatives (~22 KB)
- Cloud pricing is not competitive with Plausible/Fathom for pure web analytics
- Session recordings/heatmaps are premium add-ons on cloud plans
Matomo is best for: Teams with compliance requirements that demand full data ownership, ecommerce operations that need heatmaps and form analytics, and privacy-sensitive organizations (healthcare, finance, education) willing to invest in self-hosting.
6. Mixpanel
→ mixpanel.com | Free up to 20M events/month, then from $28/month
Best for: Product teams who need deep event analytics with identified users
Mixpanel is a product analytics tool, not primarily a web analytics tool — and that distinction matters. Its real-time feature is an Activity Feed: a live stream of every event your users fire, attached to identified profiles. You can filter the feed by event type, user property, or cohort, and click any event to see that user's full journey.
Unlike GA4, Plausible, or Fathom, Mixpanel assumes you've identified your users. Every event is attached to a distinct ID (typically tied to a user account). The live view isn't "20 anonymous visitors on your pricing page" — it's "these specific users, with these properties, doing these actions."
Mixpanel's core analytics (funnels, flows, retention, cohorts, A/B tests) are best-in-class for product teams. Where it falls short as a "real-time" tool is latency: most Mixpanel reports have a 1–5 minute data delay, and the Activity Feed is the only view with near-real-time updates. There's no live dashboard showing a map of current visitors, a count of who's online now, or a pageview spike in progress.
For marketing sites or launch monitoring, Mixpanel is the wrong tool. For deep product analytics with an identified-user live feed, it's excellent.
Real-time features:
- Activity Feed: live stream of events by identified users (1–2 min delay)
- Per-user event timeline in real time
- Cohort-filtered live event views
Pricing:
| Plan | Price | Events |
|---|---|---|
| Free | $0 | 20M events/mo |
| Growth | From $28/mo | 100M events/mo |
| Enterprise | Custom | Unlimited |
Pros:
- Identified users in the activity feed — see real customers, not anonymous sessions
- 20M events/month free — extremely generous free tier
- Best-in-class funnels, retention, and cohort analysis
- Strong data governance and export options
- Well-supported SDKs across web, mobile, and server
Cons:
- No traditional "who's online right now" dashboard
- 1–5 minute data delay — not suitable for launch war rooms
- No session replay (partners with FullStory/LogRocket but doesn't include it)
- No built-in web analytics (pageviews, bounce rate, sources) without custom tracking
- Can get expensive at high event volumes; pricing is complex
Mixpanel is best for: Product teams building apps who want an identified-user event feed and deep funnel/retention analysis — not teams looking for a live traffic dashboard.
7. Amplitude
→ amplitude.com | Free up to 50K MTUs/month, then from $49/month
Best for: Enterprise product teams who need robust analytics with real-time alerting
Amplitude is Mixpanel's closest enterprise competitor. Its real-time capabilities center on Amplitude Monitor: a live performance view that tracks your most critical metrics and fires alerts when something looks wrong. You can configure alerting on any chart in Amplitude, set anomaly detection thresholds, and get Slack or email pings when metrics deviate.
The real-time event stream in Amplitude (User Look-Up and the Activity view) shows identified user events with a 1–5 minute lag — similar to Mixpanel. Like Mixpanel, there's no traditional "visitors online now" web dashboard. Amplitude's strength is downstream: deep behavioral analytics, predictive cohorts, and the ability to use live data to trigger personalization via Amplitude Experiment.
Amplitude's free tier is 50K monthly tracked users — which sounds generous but depletes fast if you have a consumer app with many occasional users.
Real-time features:
- Amplitude Monitor: live alerting on metric anomalies
- User Look-Up: per-user event activity (1–5 min delay)
- Real-time chart refresh on dashboards
- Webhook and Slack alerts on metric changes
Pricing:
| Plan | Price | MTUs Included |
|---|---|---|
| Starter | Free | 50K MTUs/mo |
| Growth | From $49/mo | Scalable |
| Enterprise | Custom | Unlimited |
Pros:
- Strong anomaly detection and alerting — best in this list for automated monitoring
- Excellent cohort analysis, behavioral predictions, and retention curves
- Integrates with data warehouses (Snowflake, BigQuery, Redshift) for querying
- Amplitude Experiment for running A/B tests on the same platform
Cons:
- 1–5 minute data delay — not a live dashboard
- No web analytics (pageviews, bounce rate, referrers) without custom events
- 50K MTU free tier is limiting for consumer apps
- Complex pricing can escalate quickly for large products
- Steep onboarding curve; requires significant instrumentation investment
Amplitude is best for: Enterprise product teams with dedicated data engineers who need robust alerting, cohort analysis, and the ability to connect live analytics to experiments and personalization.
8. Vercel Analytics
→ vercel.com/analytics | Included with Vercel / From $14/month standalone
Best for: Next.js and Vercel-deployed sites that want instant, zero-config real-time analytics
Vercel Analytics is a web analytics product built into the Vercel deployment platform. For teams already deploying on Vercel, it's the lowest-friction real-time dashboard available: add one line to your Next.js layout and you have a live visitor count, top pages, referrers, countries, and devices — updating in near real time.
The standout feature is Web Vitals integration: alongside traffic data, Vercel Analytics shows Core Web Vitals (LCP, FID, CLS) per page, per device, and per country — in real time. This is the only tool in this comparison that natively combines traffic analytics with performance monitoring. When your homepage CLS jumps after a deploy, you see it immediately alongside the traffic drop.
What Vercel Analytics is not: it's not an event analytics tool. There's no custom event tracking, no identified users, no session replay, and no funnel analysis. It's a clean web analytics product similar in scope to Plausible or Fathom, but tightly integrated with the Vercel deployment workflow.
Real-time features:
- Live visitor count and active pages (< 5s refresh)
- Real-time Web Vitals per page and per device
- Top referrers, countries, devices in real time
- Instant visibility after deploy (zero config for Next.js)
Pricing:
| Plan | Price | Notes |
|---|---|---|
| Hobby (Vercel) | Free | Limited to 2.5K events/mo |
| Pro Analytics | $14/mo | 10K events/mo included |
| Pro (higher) | Usage-based | $0.65/1K events above included |
Pros:
- Zero configuration for Next.js / Vercel-deployed apps
- Real-time Web Vitals alongside traffic data — unique in this comparison
- Fast, lightweight (edge-native analytics, no additional JS)
- Seamlessly integrates with Vercel deployment workflow
Cons:
- Only useful if you're already on Vercel — no value for non-Vercel apps
- No custom event tracking, funnels, or identified users
- Limited depth compared to Plausible or GA4 for pure analytics
- Can get expensive at scale via event-based pricing
- Data is not exportable or queryable via SQL
Vercel Analytics is best for: Next.js teams deployed on Vercel who want a zero-config real-time dashboard with Web Vitals built in, without adding another analytics SDK.
9. Microsoft Clarity
→ clarity.microsoft.com | Free, no limits
Best for: Teams who want free session recordings and heatmaps alongside a basic live view
Microsoft Clarity is unusual: it's completely free, with no pageview limits, no user limits, and no paid tier. Microsoft funds it as a mechanism to gather behavioral data to improve Bing and other Microsoft products — which is worth knowing when evaluating it for privacy-sensitive use cases.
The real-time capabilities are basic. Clarity shows a live session feed — recent sessions, updating roughly every 30 seconds — with immediate access to session recordings. The real-time dashboard is minimal: there's no live visitor count displayed prominently, no live map, and no live event stream. What Clarity excels at is the playback interface. Session recordings are high-quality, include rage-click detection, dead-click flagging, and scroll maps, and load fast.
Clarity is frequently used alongside GA4 or Plausible — it adds session replay and heatmaps to a stack that provides the live traffic dashboard, rather than replacing it.
Real-time features:
- Recent sessions feed (~30s delay)
- Immediate session recording access
- Rage-click and dead-click live detection
- Heatmaps (aggregated, not live)
Pricing: Completely free. No tiers, no limits.
Pros:
- Completely free — no usage limits, no paid tier
- Session recordings and heatmaps at no cost
- Rage-click and dead-click detection built in
- Easy to install (one tag)
- Integrates with GA4 (sessions link between both tools)
Cons:
- No traditional live visitor dashboard — not suitable for launch monitoring
- Data is used by Microsoft to improve its own products (privacy consideration)
- No identified users or custom event analytics
- No self-host option
- No data export or API
- ~30-second real-time delay; not suitable for true live monitoring
Microsoft Clarity is best for: Teams who want free session recordings and heatmaps alongside another tool that provides the live traffic dashboard.

Frequently Asked Questions
What is the difference between real-time analytics and regular analytics? Regular analytics tools process data in batches — your dashboard updates every few hours. Real-time analytics tools process events as they arrive and update dashboards within seconds or minutes. Real-time is critical for launch monitoring, incident response, and identifying conversion problems as they happen.
Do I need real-time analytics, or is batch analytics enough? For most day-to-day product decisions, batch analytics is sufficient. Real-time becomes essential when you're actively launching (Product Hunt, Hacker News), monitoring a deploy for regressions, running a time-limited promotion, or responding to an incident. If you regularly do any of these, real-time analytics is worth the investment.
Can I see which specific person is on my site right now? Yes — but only with tools that support identified users. PostHog, Matomo, and Mixpanel all let you associate sessions with a user ID or email. GA4, Plausible, and Fathom show anonymous sessions only.
What's the best free real-time analytics tool? If you want a live visitor count and basic web analytics: Google Analytics 4 or Microsoft Clarity (both free). If you want identified users and product analytics: PostHog (1M events/month free). If you need unlimited session recordings: Microsoft Clarity. There's no single best — it depends on what "free" needs to give you.
Which real-time analytics tool is most privacy-friendly? Plausible and Fathom are the most privacy-friendly by default — cookieless, no consent banner required in most jurisdictions, minimal data collection. Matomo (self-hosted) gives you maximum control. PostHog and Mixpanel collect more data by design but give you data residency options.
Can I self-host a real-time analytics platform? Yes — PostHog, Plausible, and Matomo all offer self-hosted options. Matomo is the most established (Docker or any PHP/MySQL server). PostHog has a fully-featured Docker Compose deployment. Plausible can be self-hosted but the free self-hosted version lags behind the cloud version on features.
Is GA4 legal in Europe? It's complicated. Several European data protection authorities (including Austria, France, Italy, and Denmark) have ruled or indicated that standard GA4 configurations violate GDPR because they transfer data to the US. Google has made changes to address this, but the legal situation remains unresolved in some jurisdictions. If EU compliance is critical, Plausible, Fathom, or Matomo (self-hosted in the EU) are safer choices.
How is real-time analytics latency measured? Latency is the time between a user action (page load, event fire) and that data appearing in the analytics dashboard. Best-in-class tools like PostHog, Plausible, and Fathom achieve < 5-second end-to-end latency. GA4's Realtime report updates every ~5 minutes. Product analytics tools like Mixpanel and Amplitude have 1–5 minute delays. Batch analytics tools have hours.
The Bottom Line
There is no single best real-time analytics platform — the right answer depends on what you're building, who you're building for, and what question you need answered in real time.
- For launch monitoring and live traffic dashboards: PostHog, Plausible, or Fathom
- For identified users and product analytics: PostHog or Mixpanel
- For full data ownership and compliance: Matomo (self-hosted)
- For zero-config Next.js analytics with Web Vitals: Vercel Analytics
- For free heatmaps and session recordings: Microsoft Clarity (alongside another tool)
- For enterprise alerting and anomaly detection: Amplitude Monitor
Most product teams end up with two tools: a live web analytics dashboard (Plausible, Fathom, or GA4) plus a product analytics platform with event-level data (PostHog, Mixpanel, or Amplitude). Whether you consolidate into one tool or keep them separate depends on your team's size, budget, and how tightly integrated you need the live view to be with the rest of your analytics stack.
