PostHog is an open-source product analytics platform for teams that want to understand user behavior and ship product changes from the same place. It combines analytics, experimentation, and feedback tools so product, engineering, and growth teams can measure what users do, test ideas, and act on results without stitching together separate systems. Its product suite includes Event Tracking, Session Recording, Feature Flags, Heatmaps, A/B Testing, Product Analytics, User Feedback, Retention Analysis, and Custom Dashboards. PostHog also offers a public API for custom integrations and supports web and mobile applications. The company says it has over 60,000 customers, serves 100+ countries, and more than 90% of companies use it for free.
Start with a monthly free tier that includes analytics, session replay, feature flags, experiments, surveys, and data warehouse usage limits.
Invite as many teammates as needed without per-seat friction, which helps product, engineering, and growth collaborate on the same data.
Get help through documentation and community support on the free plan, with a dedicated support channel available for pro users.
Use the public API for custom integrations and developer workflows, so PostHog can fit into internal tools and automation.
Capture product events across web and mobile apps, giving teams the raw activity data needed for funnels, cohorts, and usage analysis.
Watch individual user sessions to spot confusion, bugs, and drop-off points, with free-tier limits for recordings and mobile recordings.
Roll out features gradually and control exposure by user or project, then connect flag changes to experiment and analytics data.
Analyze events, funnels, and usage patterns in one place, with usage-based pricing that scales after the monthly free event allowance.
Product managers use PostHog to monitor a launch from first event to retention, using Product Analytics and Custom Dashboards to see whether new users activate and return. Session Recording helps them inspect friction points before the team iterates.
Engineers use PostHog to release changes gradually, using Feature Flags to gate access and A/B Testing to compare outcomes. They can pair that with Event Tracking to confirm whether the rollout improves conversion or engagement.
Support and research teams use PostHog to collect User Feedback while watching Session Recording for the same users. That combination helps them turn complaints into specific fixes and verify whether the next release reduces drop-off.
Yes. PostHog offers a free plan with no time limit, and the company says more than 90% of companies use it for free. The free tier includes basic analytics features, session recording, and user feedback capabilities.
Yes. PostHog has a public API for custom integrations and developer workflows. The vendor also describes it as a complete API for developers.
Yes. PostHog can be self-hosted, and the vendor points users to its documentation for setup instructions. That makes it a fit for teams that need more control over deployment or data residency.
The platform also says it has over 300 integrations so it can fit into a broad stack.
Yes. PostHog supports web and mobile applications, and the pricing page includes mobile session replay as a supported capability. The vendor notes there is not a standalone mobile app.
Data retention depends on plan. The vendor says paid plans retain data for 7 years, while the free plan retains data for 1 year.
PostHog's enterprise page lists SOC 2 Type II certification, HIPAA compliance, GDPR readiness, and the EU-U.S. Data Privacy Framework. It also shows a transparency report with 27% flair progress.
The vendor recommends starting with the Free plan to get an accurate volume projection after a few days. That gives you a practical read on event volume before you commit to higher usage.
Editor's read
Check the free-tier usage limits around recordings and mobile recordings before rollout, since those caps can shape how quickly you need Pro. Also verify whether your workflow depends on the dedicated support channel, which is listed for Pro users.
