4 Best Free Alternatives to PostHog in 2026
By Noahlast updated pricing verified
Compared: free alternatives to PostHog
| Alternative | Best for | Standout | Biggest weakness | Learning curve | Price |
|---|---|---|---|---|---|
| PostHogreference | product and engineering teams who want analytics, session replay, feature flags, and error tracking in one platform instead of stitching together separate tools | One platform combining product analytics, session replay, feature flags/A-B testing, error tracking, and a data warehouse, each billed on its own usage-based rate that drops at higher volume. | Usage-based pricing across many separate products (events, replays, flags, surveys, data warehouse rows) makes total monthly cost harder to predict than a single flat per-seat price, and some enterprise features live in a separate proprietary ('ee') license rather than the fully open-source core. | Moderate | Free |
| Mixpanel | product teams tracking funnels, retention, and feature adoption across web and mobile without writing SQL | Behavioral cohorts and multi-touch attribution built on Mixpanel's proprietary Arb query engine, fast enough for ad hoc exploration across tens of millions of monthly events. | Growth-plan pricing is not published as a flat number; it scales with event volume through a calculator, which makes budgeting harder to predict than a fixed per-seat price, and event-based pricing can get expensive fast for high-traffic products compared to flat-rate competitors. | Moderate | Free |
| Amplitude | product teams that need behavioral analytics, session replay, and lightweight experimentation in one tool, and prefer usage-based pricing tied to event volume over per-seat licensing | Bundles product analytics, session replay, and feature experimentation under one usage-based pricing model, plus native MCP connectivity so AI coding tools like Claude and Cursor can query product data directly. | Pricing above the free 2-million-event tier is usage-based and largely hidden behind "contact sales" for Growth and Enterprise, making it hard to budget for a scaling product without a sales conversation; heavy instrumentation can also drive event volume, and cost, up faster than teams expect. | Moderate | Free |
| Google Analytics | businesses that want free, event-based web and app analytics tightly integrated with Google Ads for campaign measurement | Free, unlimited-scale analytics for most businesses, with machine-learning-driven insights and direct integration into Google Ads for measuring campaign ROI without a separate tool. | The GA4 event-based data model and reorganized interface represented a steep relearning curve for teams used to the older Universal Analytics, and standard GA4 properties still apply data sampling and shorter retention windows that only Google Analytics 360's custom, undisclosed pricing removes. | Moderate | Free |
| Heap | product teams that want non-technical staff to build and adjust event funnels retroactively, without waiting on engineering to instrument new tracking code | Autocapture records every interaction from install without requiring events to be pre-defined, so teams can build new funnels against historical data instead of only data collected after an event was manually tagged. | Pricing above the 10,000-session free tier is not published; Growth, Pro, and Premier all require a sales conversation, and reviewers report costs climbing sharply as session volume scales, prompting some teams to switch at renewal. | Low | Free |

Heap1.Mixpanel — best PostHog alternative for product teams tracking funnels, retention, and feature adoption across web and mobile without writing SQL
Mixpanel is the best PostHog alternative for product managers, designers, and engineers who want to track funnels, retention, and cohorts without writing SQL, a self-serve analytics focus distinct from PostHog's broader, multi-product bundle. Mixpanel's free tier covers up to 1 million events per month with 10,000 session replays, a smaller volume than PostHog's own free tier of 1 million analytics events plus 5,000 session replays, though Mixpanel holds a 4.5/5 rating from 146 Capterra reviews and a 4.9/5 rating from 90 Product Hunt reviews, both more review volume than PostHog's single 5/5 rating from 253 Product Hunt reviews on one platform. Mixpanel runs on its proprietary Arb query engine for fast ad hoc queries across large event volumes, and bundles session replay, A/B testing, and MCP integrations for Slack, Claude, ChatGPT, and Cursor directly into the product, similar in scope to PostHog's own bundled feature set but without PostHog's error tracking or data warehouse components. PostHog remains the better choice for teams that specifically want error tracking, surveys, and a data warehouse alongside analytics in one open-source, MIT-licensed core: Mixpanel's Growth-plan pricing is not shown as a flat number and scales with event volume through a calculator, the same usage-based unpredictability PostHog's own per-product pricing carries, and Mixpanel is closed-source, unlike PostHog's MIT-licensed, self-hostable core.
Compared to PostHog: 4.5/5 rating from 146 Capterra reviews plus 4.9/5 from 90 Product Hunt reviews vs PostHog's single 5/5 from 253 Product Hunt reviews, proprietary Arb query engine for fast ad hoc analysis vs PostHog's broader multi-product bundle, closed-source vs PostHog's MIT-licensed, self-hostable core
Wins:Rated on two platforms (4.5/5 from 146 Capterra reviews, 4.9/5 from 90 Product Hunt reviews) versus PostHog's single 5/5 rating from 253 Product Hunt reviews · Fast ad hoc queries across large event volumes via the proprietary Arb engine, purpose-built for funnel and retention analysis · MCP integrations connect Mixpanel data directly into Slack, Claude, ChatGPT, and Cursor
Loses:Closed-source, unlike PostHog's MIT-licensed core that's available on GitHub and self-hostable · Free tier covers 1 million events/month, below PostHog's own free tier of 1 million analytics events plus 5,000 session replays and more per month · No error tracking, surveys, or data warehouse built in, features PostHog bundles into the same platform
Pros
- Free tier genuinely usable up to 1M events/month with core funnel and retention analysis included.
- Fast ad hoc queries across large event volumes via the proprietary Arb engine.
- Session replay and A/B testing built into the same product as the analytics.
- MCP integrations connect Mixpanel data directly into Slack, Claude, ChatGPT, and Cursor.
Cons
- Growth plan pricing is usage-based and not shown as a flat number on the pricing page, making costs harder to forecast.
- Event-based pricing can climb quickly for high-traffic consumer apps compared to flat-rate tools.
- No SQL access on lower tiers limits users who want to run custom warehouse-style queries directly.
- Requires disciplined event-tracking taxonomy up front; poorly named events make later analysis messy.
Pricing: Free — Free up to 1 million events/month, matching PostHog's own 1M-event free tier; Mixpanel's Growth plan then bills usage-based via a calculator rather than PostHog's flat per-event rate (verified undefined NaN, NaN)
2.Amplitude — best PostHog alternative for product teams that need behavioral analytics, session replay, and lightweight experimentation in one tool, and prefer usage-based pricing tied to event volume over per-seat licensing
Amplitude is the best PostHog alternative for product teams that want the most generous free event allowance among these alternatives, plus session replay and feature experimentation bundled in, a scope close to PostHog's own multi-product design. Amplitude's Free plan covers up to 2 million tracked events per month with no credit card required, double PostHog's own free tier of 1 million analytics events per month. Amplitude holds a 4.6/5 rating from 68 Capterra reviews, a smaller sample than PostHog's 253 Product Hunt reviews at 5/5, though on a different review platform. Amplitude bundles session replay (10,000 sessions/month on the free tier) and feature experimentation directly into the product, plus native MCP connectivity so AI coding tools like Claude and Cursor can query product data directly, a capability PostHog also documents through its own tool integrations. PostHog remains the better choice for teams that specifically want error tracking, surveys, and a self-hostable MIT-licensed core alongside analytics: Amplitude's Growth and Enterprise tiers are hidden behind "contact sales" with no published rate, the same usage-based opacity PostHog's own per-product pricing carries beyond its free tier, and Amplitude is closed-source, unlike PostHog's open-core model with a dedicated posthog-foss repository.
Compared to PostHog: Free tier covers 2 million events/month vs PostHog's 1 million analytics events/month, session replay and feature experimentation bundled in similar to PostHog's own multi-product design, closed-source vs PostHog's MIT-licensed, self-hostable core
Wins:Free tier covers 2 million events/month with no credit card required, double PostHog's own 1-million-event free tier · Session replay and feature experimentation are built into the same product, similar in scope to PostHog's bundled feature set · Native MCP support lets AI coding assistants query product analytics data directly, alongside SDKs across TypeScript, Python, Go, Swift, and Kotlin
Loses:Closed-source, unlike PostHog's MIT-licensed core that's available on GitHub with a dedicated posthog-foss repository · No error tracking, surveys, or data warehouse built in, features PostHog bundles into the same platform · Growth and Enterprise pricing is hidden behind "contact sales," the same usage-based opacity PostHog's own per-product pricing carries beyond its free tier
Pros
- Free tier covers 2 million events/month with no credit card required, generous compared to many analytics competitors.
- Session replay and feature experimentation are built in, reducing the need for separate tools.
- Native MCP support lets AI coding assistants query product analytics data directly.
- SDKs across TypeScript, Python, Go, Swift, and Kotlin cover most product stacks.
Cons
- Growth and Enterprise pricing is not published; both require a sales conversation to get a quote.
- Usage-based pricing means costs can rise with instrumentation depth, not just company size or seats.
- Advanced session replay volume (beyond the free tier's 10,000/month) requires moving to a paid plan.
- Setup and event-taxonomy design require more upfront planning than simpler analytics tools.
Pricing: Free — Free up to 2 million events/month, double PostHog's own 1-million-event free tier; both vendors then bill usage-based beyond their free limits (verified undefined NaN, NaN)
3.Google Analytics — best PostHog alternative for businesses that want free, event-based web and app analytics tightly integrated with Google Ads for campaign measurement
Google Analytics is the best PostHog alternative for businesses that want free, event-based web and app analytics with no meaningful traffic cap, tightly integrated with Google Ads, rather than PostHog's usage-based, per-product pricing model. Google Analytics 4 is free for businesses of any size with no published event limit, a structurally different offer from PostHog's free tier, which caps at 1 million analytics events per month before usage-based billing kicks in. Google Analytics holds a 4.7/5 rating from 8,101 Capterra reviews, by far the largest review base of any product in this comparison, more than 30 times PostHog's own 253 Product Hunt reviews. Google Analytics' machine-learning-driven insights (predicted churn, purchase likelihood) and direct Google Ads integration for measuring campaign ROI are built in at no extra cost, a marketing-analytics angle PostHog's product-analytics-first design doesn't specifically target. PostHog remains the better choice for product and engineering teams that specifically want session replay, feature flags, error tracking, and a self-hostable MIT-licensed core in one platform: Google Analytics 4's event-based model and reorganized interface represented a steep relearning curve for teams used to the older Universal Analytics, and standard GA4 properties apply data sampling and shorter retention windows that only the custom-priced, undisclosed Google Analytics 360 tier removes.
Compared to PostHog: free for businesses of any size with no published event cap vs PostHog's 1-million-event free tier, 4.7/5 rating from 8,101 Capterra reviews vs PostHog's 253 Product Hunt reviews, native Google Ads integration and ML-driven insights vs PostHog's product-analytics-first, session-replay-and-flags bundle
Wins:Free for businesses of any size with no meaningful traffic cap, unlike PostHog's 1-million-event free tier before usage-based billing begins · 4.7/5 rating from 8,101 Capterra reviews, more than 30 times PostHog's own 253 Product Hunt reviews · Deep, native integration with Google Ads for tying analytics directly to campaign performance, at no extra cost
Loses:No session replay, feature flags, error tracking, or data warehouse built in, features PostHog bundles into the same platform · Not open source or self-hostable, unlike PostHog's MIT-licensed core available on GitHub · Standard (free) properties apply data sampling and shorter data-retention windows than the custom-priced, undisclosed Google Analytics 360 tier
Pros
- Free for businesses of any size, with no meaningful traffic cap for most use cases.
- Deep, native integration with Google Ads for tying analytics directly to campaign performance.
- Cross-platform (web + app) tracking in a single GA4 property.
- Machine-learning-driven insights (predictive metrics, anomaly detection) built in at no extra cost.
Cons
- GA4's event-based model and menu reorganization created a steep relearning curve versus the older Universal Analytics.
- Standard (free) properties apply data sampling and shorter data-retention windows than the paid 360 tier.
- Google Analytics 360 pricing is not published and requires a sales conversation, making budgeting difficult upfront.
- Some users report GA4 reports are harder to pull and customize compared to the legacy interface.
Pricing: Free — $0/month, free for businesses of any size, vs PostHog's free tier capped at 1 million analytics events/month before usage-based billing (verified undefined NaN, NaN)
4.Heap — best PostHog alternative for product teams that want non-technical staff to build and adjust event funnels retroactively, without waiting on engineering to instrument new tracking code
Heap is the best PostHog alternative for product teams that want non-technical staff to build and adjust event funnels retroactively, without waiting on engineering to instrument new tracking code, an autocapture model distinct from PostHog's event-based analytics that still requires defining events in advance. Heap's Free plan covers up to 10,000 monthly sessions and 6 months of data history, a different unit than PostHog's own free tier of 1 million analytics events per month, making a direct volume comparison imprecise. Heap holds a 4.5/5 rating from 42 Capterra reviews, a smaller sample than PostHog's 253 Product Hunt reviews at 5/5. Heap's autocapture records every click, tap, and form submission from install with no pre-defined events required, so a product manager can define a new funnel step after the fact and see historical data immediately, a retroactive-analysis capability PostHog's forward-looking event tracking doesn't offer in the same way. PostHog remains the better choice for teams that specifically want session replay, feature flags, error tracking, surveys, and a self-hostable open-source core all in one platform: Heap's pricing above the 10,000-session free tier is not published, and reviewers report costs climbing sharply as session volume grows, a budgeting problem PostHog's own transparently-tiered per-event pricing avoids by publishing its declining per-unit rates.
Compared to PostHog: autocapture records every interaction with no pre-defined events vs PostHog's forward-looking event tracking, Free tier covers 10,000 monthly sessions vs PostHog's 1 million analytics events/month, no published pricing above the free tier vs PostHog's published declining per-event rates
Wins:Autocapture records every interaction on install, so new funnels can be built against historical data with no re-instrumentation, unlike PostHog's event-based tracking · Non-technical team members can define and adjust tracked events without engineering involvement · Free tier includes SSO and unlimited enrichment sources, not just a stripped-down trial
Loses:No published pricing above the 10,000-session free tier; Growth, Pro, and Premier all require a sales quote, unlike PostHog's published, transparently declining per-event rates · No session replay volume comparable to PostHog's 5,000-replay free tier is documented, and session replay is an add-on on Heap's Pro plan rather than included · No feature flags, error tracking, or data warehouse built in, features PostHog bundles into the same platform
Pros
- Autocapture records every interaction on install, so new funnels can be built against historical data with no re-instrumentation.
- Non-technical team members can define and adjust tracked events without engineering involvement.
- Sense AI enables natural-language queries against behavioral data.
- Free tier includes SSO and unlimited enrichment sources, not just a stripped-down trial.
Cons
- No published pricing above the 10,000-session free tier; Growth, Pro, and Premier require a sales quote.
- Reviewers report costs rising sharply as monthly session volume grows.
- Session replay is an add-on rather than included in the base Pro plan.
- Now part of Contentsquare following acquisition, which has changed roadmap priorities for some long-time users.
Pricing: Free — Free up to 10,000 monthly sessions vs PostHog's free tier of 1 million analytics events/month; Heap's paid tiers above free require a sales quote, unlike PostHog's published per-event rates (verified undefined NaN, NaN)
