Best Free Product Analytics Tools in 2026
PostHog gives you 1 million free events a month plus session replay and feature flags in one platform. Amplitude and Mixpanel both cap their free plans on usage (tracked users or events) rather than time, so they work for indefinite side projects. Heap auto-captures every click for free up to 10,000 sessions a month, and Countly is the pick if you want to self-host and never hit a usage wall at all.
Event tracking, funnels, retention, and session replay with a free tier that survives real product usage, not a 14 day trial.
Of the 10,000+ tools Toolradar tracks, 23 in the Product Analytics category offer a genuine free tier, and most of them cap it hard enough that you hit a paywall before you learn anything useful. The good news: a handful of the category's biggest names, PostHog, Amplitude, Mixpanel, and Heap among them, ship free plans generous enough to run a real product on for months before you need a credit card.
This list only includes tools that track product usage: events, funnels, retention cohorts, feature adoption, and session replay. It deliberately excludes pure web analytics tools like Google Analytics and Matomo, which measure pageviews and traffic sources rather than in-app behavior. Every pick below was checked against its current 2026 pricing page for its actual free-tier limit (events, sessions, or tracked users), and every tool is a live, actively maintained product. We dropped a couple of pool candidates whose free tier is undocumented or whose product is winding down.

Teams that want analytics, feature flags, and session replay without stitching together three tools.
- Pro: 1 million free events every month, no time limit
- Pro: 5,000 session replays and 1,500 survey responses included free
- Pro: Feature flags, A/B testing, and error tracking bundled into the same free plan
- Con: Identified (logged-in) events can cost up to 4x more once you exceed the free tier
- Con: Dashboard has a learning curve given how many products are bundled in
PostHog's pricing is quite generous, especially with its robust free tier offering 1M events and unlimited seats.
Watch out
Overage fees for events beyond free tier
Product teams that want strong cohort and behavioral cohorting tools on a real free tier.
- Pro: Free Starter plan covers up to 10,000 monthly tracked users
- Pro: Session replay is included on the free plan, not gated behind a paid tier
- Pro: 12 months of data retention on the free plan
- Con: Capped on monthly tracked users, so a high-traffic low-signup site burns through the limit fast
- Con: Advanced experimentation and predictive features require a paid plan
Amplitude free Starter plan is genuinely useful: 10K monthly tracked users (MTUs), 10M events, session replay, and unlimited feature flags.
Watch out
MTU-based pricing can be expensive for products with many low-engagement users. A marketing site with 500K monthly visitors costs far more on Amplitude (MTU-based) than Mixpanel (event-based) if each visitor generates few events.
Teams that want unlimited seats on the free plan and don't mind an event-volume cap.
- Pro: Free plan covers up to 1 million monthly events
- Pro: Unlimited team seats on the free plan, unusual for the category
- Pro: 10,000 session replays a month included free
- Con: Only 5 saved reports on the free plan
- Con: High-event-volume apps (lots of small tracked actions) will hit the cap faster than a per-user model would
Mixpanel's free tier (1M events) is generous.
Teams that don't want to hand-instrument every event before they can see funnels.
- Pro: Free plan covers up to 10,000 monthly sessions
- Pro: Auto-capture means you get historical data on events you didn't think to track in advance
- Pro: Unlimited enrichment sources and six months of data history included free
- Con: Exceeding the session limit blocks access to your own dashboard until you upgrade
- Con: Paid tiers are quote-based and start in the thousands per year, a steep jump from free
Heap's pricing is fair for its Free and Growth tiers, offering good value for startups and growing businesses.
Watch out
Session Replay is an add-on, not included.
Engineering and support teams debugging specific user sessions, not just tracking aggregate funnels.
- Pro: Free plan includes 1,000 sessions a month with full replay
- Pro: Combines session replay with JavaScript error tracking and performance metrics in one tool
- Pro: 3 team seats included on the free plan
- Con: 1,000 sessions a month is tight for anything beyond a small app or early beta
- Con: Only 1 month of data retention on the free plan
LogRocket's pricing is fair, offering a generous free tier and a competitive entry point for teams.
Teams that want to run A/B tests and read the analytics behind them in the same product.
- Pro: Free tier covers up to 1 million monthly tracked users
- Pro: Unlimited feature seats on the free plan
- Pro: Statistical rigor (CUPED, sequential testing) available free, usually an enterprise feature elsewhere
- Con: Steeper learning curve if you only want simple event analytics, not experimentation
- Con: Pricing and roadmap are in flux following the 2026 Amplitude acquisition
Statsig's pricing is quite generous, especially with a robust Free tier offering 50M events.
Watch out
Overage fees for events beyond tier limits
Teams that want to eliminate usage caps entirely by self-hosting, especially with data-privacy requirements.
- Pro: Countly Lite (Community Edition) is free forever with no event or session ceiling once self-hosted
- Pro: Full data ownership, useful for teams with GDPR or data-residency constraints
- Pro: Covers web, mobile, and desktop SDKs out of the box
- Con: Self-hosting means you own the server, uptime, and upgrades
- Con: Advanced modules (attribution, predictive churn) are gated to paid Enterprise or Flex plans
Countly's pricing is quite generous, especially with its robust free tiers.
Watch out
Push notifications are add-on
Indie developers and privacy-conscious teams shipping native or Electron apps.
- Pro: Free plan covers up to 20,000 events a month
- Pro: Fully open-source, including server and SDKs, so you can self-host with no cap at all
- Pro: No cookies or personal data collected by default, useful for privacy-first products
- Con: Much smaller feature set than PostHog or Amplitude: no session replay, no feature flags
- Con: 20,000 events a month is a low ceiling for anything beyond a small hobby app on the hosted plan
Aptabase's pricing is quite generous, especially with a robust Free tier offering 20K events/month.
Watch out
Potential overage fees if exceeding event limits
Small sites that want heatmaps and a handful of session recordings without paying anything.
- Pro: Free plan available at $0 a month indefinitely, not a time-limited trial
- Pro: Includes heatmaps, session recordings, and 2 funnel reports
- Pro: Google Analytics and Slack integrations included free
- Con: Only 500 recorded sessions a month, exhausted within days on any site with real traffic
- Con: Just 10 tracked events on the free plan versus 20 to 40 on paid tiers
It's best for businesses of all sizes looking for comprehensive behavior analytics.
Watch out
Overage fees for exceeding session limits
Engineering-led teams that want to self-host experimentation and read results against their own warehouse.
- Pro: Self-hosted edition is free with unlimited users under the MIT license
- Pro: Cloud Starter plan is free for up to 3 users with unlimited feature flags and experiments
- Pro: Connects directly to your existing data warehouse instead of forcing a new event pipeline
- Con: Not a general-purpose event analytics tool; it's built around flags and experiments specifically
- Con: Self-hosting requires running and maintaining your own infrastructure
The Open Source option provides exceptional value for those willing to self-host, making it ideal for technical teams prioritizing cost control and customization.
What Is a Product Analytics Tool?
A product analytics tool tracks what users actually do inside your app: which features they click, where they drop off in a signup flow, how often they return, and whether a new feature moves retention. Unlike web analytics, which reports pageviews and traffic sources for marketing sites, product analytics is built around events (a click, a form submit, a purchase) tied to a specific user, so you can build funnels, cohorts, and retention curves from that event stream.
Most tools in this category share a similar core: an SDK or API that sends events, a dashboard for funnels and retention, and increasingly, session replay so you can watch the exact sequence of clicks behind a confusing metric.
Why a Real Free Tier Matters
Product analytics only pays off once you have enough event volume to see patterns, and that takes weeks or months, not a 14-day trial. A free tier with a hard event or session cap that resets monthly lets you instrument a real product, watch a cohort actually retain or churn, and decide whether the tool fits before you commit spend. It also matters for solo founders and small teams validating a product where analytics spend competes directly with runway.
The caps vary a lot by vendor and by what they meter (events, monthly tracked users, or sessions), so the "best" free tier depends on your traffic shape: a high-event, low-user B2B app fits a per-event cap better than a per-session cap, and vice versa.
Key Features to Look For
Event and funnel tracking (Essential)
Custom event definitions and multi-step funnel analysis are the baseline; without them you can't see where users drop off.
Retention and cohort analysis (Essential)
Cohort-based retention curves show whether a feature or campaign actually keeps users coming back, not just whether they signed up.
Free tier event or session cap (Essential)
Look at the actual metered unit (events, MTUs, or sessions) and check it against your real traffic before assuming a tool's free plan fits.
Session replay (Important)
Watching an actual session next to the funnel data turns 'users drop off here' into 'users get stuck on this specific button.'
Data retention window (Important)
Free plans often cap history at 1 to 12 months; a short window makes year-over-year retention analysis impossible.
Self-hosting option (Nice to have)
Open-source, self-hostable tools remove the usage cap entirely at the cost of running your own infrastructure.
Mistakes to Avoid
- ×
Picking a tool based on its logo recognition instead of checking whether it meters events, sessions, or tracked users, the metric that actually determines when you'll hit the paywall.
- ×
Instrumenting dozens of events on day one instead of starting with 5 to 10 that map to real product decisions, which burns through a free-tier cap fast for no analytical benefit.
- ×
Ignoring data retention limits on free plans; a 1 month retention window makes it impossible to compare this quarter's retention to last quarter's.
- ×
Assuming 'freemium' means 'free forever' without checking the actual current terms, since vendors change limits and some free tiers get pulled entirely.
- ×
Choosing a session-replay-first tool like LogRocket or Mouseflow when the real need is funnel and retention analysis, or vice versa; the two use cases favor different products.
Expert Tips
- →
Estimate your monthly event or session volume before picking a tool. A B2B app with 500 daily active users generating 50 events each blows past a 1,000-session cap in a day but might stay under a 1 million-event cap for months.
- →
- →
Self-hosted open-source options (Countly, GrowthBook, or PostHog's OSS edition) remove the usage ceiling entirely, but budget real engineering time for setup and upgrades before you commit.
- →
Combine a free analytics tool with a free session replay tool if neither single free tier covers both well; PostHog and Amplitude bundle replay, but LogRocket's replay quality is still a notch above either at low volume.
- →
Re-check the vendor's current pricing page before instrumenting anything. Free-tier limits shift often, and at least one 2026 pool candidate (Smartlook) has stopped accepting new signups entirely.
The Bottom Line
PostHog is the strongest all-around free pick because its 1 million events a month covers analytics, replay, and feature flags in one bill. Amplitude and Mixpanel are close seconds if you want a more analytics-first, less bundled tool, and Countly is the only option here that removes the usage cap entirely by self-hosting. Of the 10,000+ tools Toolradar tracks, 23 in the Product Analytics category offer a genuine free tier, and the ten above are the ones worth actually building on.
Frequently Asked Questions
What is the best free product analytics tool?
PostHog is the strongest overall pick, with 1 million free events a month covering event tracking, funnels, session replay, and feature flags in a single platform. Amplitude and Mixpanel are close alternatives if you want a more analytics-focused tool, each capping their free tier on tracked users or events rather than time.
Is PostHog really free?
Yes. PostHog's free tier includes 1 million events, 5,000 session replays, and 1,500 survey responses every month with no time limit, and 97% of PostHog accounts stay on that free tier indefinitely. You only pay once you exceed those monthly limits, and the open-source self-hosted edition removes the cap entirely.
What's the difference between product analytics and web analytics?
Web analytics tools like Google Analytics and Matomo track pageviews, sessions, and traffic sources for marketing sites. Product analytics tools like PostHog, Amplitude, and Mixpanel track user-level events inside a logged-in product, like feature clicks, funnel steps, and retention, so you can measure engagement and churn rather than just visits.
Can I run product analytics without paying anything?
Yes, for meaningful usage volume. PostHog, Amplitude, Mixpanel, Statsig, and Heap all offer free tiers generous enough to run a small-to-mid-size product on for months, and Countly and GrowthBook can be self-hosted for free indefinitely with no usage cap at all, at the cost of running your own server.
Which free product analytics tool has the best session replay?
LogRocket has the most polished replay experience but caps its free plan at 1,000 sessions a month. PostHog and Amplitude both bundle solid session replay into their free analytics plans (5,000 and included respectively), which is a better fit if you want replay and event analytics from a single vendor.
