Open-source, all-in-one product analytics platform combining event tracking, session replay, feature flags, A/B testing, surveys, error tracking, and a data warehouse — with self-hosting option for complete data control.
All-in-one product analytics — track user behavior, run experiments, replay sessions, manage feature flags, and warehouse your data in one open-source platform.
PostHog stands out as the only product analytics platform that gives you complete control over your data while providing enterprise-grade analytics capabilities. Unlike traditional analytics tools that require you to send data to third-party servers, PostHog offers both cloud-hosted and self-hosted deployment options, making it ideal for companies with strict data privacy requirements or those operating in regulated industries. The platform combines event tracking, feature flags, session recordings, A/B testing, surveys, error tracking, and a built-in data warehouse in a single unified interface, eliminating the need to stitch together multiple tools and maintain separate user identification across systems.
PostHog's SQL-based query interface gives technical teams unprecedented flexibility to analyze data exactly how they want, going far beyond pre-built dashboard widgets. The session recordings feature captures actual user interactions with your application, providing qualitative context that pure analytics data can't match — you can watch exactly what users did when they encountered errors or dropped out of conversion funnels.
PostHog's feature flag system supports percentage rollouts, multivariate testing, and complex targeting rules based on user properties, cohorts, or custom logic. The platform's open-source nature means you can modify and extend functionality, contribute to development, and avoid vendor lock-in that plagues proprietary analytics solutions.
The pricing model is genuinely usage-based with generous free tiers across every product — 1M analytics events, 5K session recordings, 1M feature flag requests, and more each month at no cost. Over 90% of companies using PostHog pay nothing. When you do exceed free limits, per-unit pricing decreases at scale, and you can set hard billing limits per product to prevent surprise bills.
PostHog has expanded significantly beyond core analytics into a full product development platform. The data warehouse syncs with external sources, data pipelines handle event routing and batch exports, LLM analytics tracks AI feature usage, and PostHog AI provides built-in credits for AI-powered insights. Error tracking, surveys, and workflow automation round out the platform.

PostHog is the most complete open-source product analytics suite, combining event tracking, session replay, feature flags, A/B testing, surveys, error tracking, and a data warehouse in one platform. The generous free tier covers most startups entirely. Self-hosting gives full data control. The all-in-one approach reduces tool sprawl, but individual features may not match best-of-breed depth.
Automatically tracks clicks, page views, and form submissions without manual event implementation, with retroactive analysis capabilities. SQL query interface enables custom analysis beyond pre-built dashboards.
Use Case:
Analyze user interactions on any page element without prior tracking setup, then create custom events based on discovered patterns and build SQL-powered retention cohorts.
Privacy-respecting session replay captures user interactions while automatically masking sensitive form fields and PII. Integrated error tracking captures exceptions and links them to specific user sessions.
Use Case:
Watch actual user sessions where checkout abandonment occurred, see the exact JavaScript error that triggered, and identify the specific UX friction point causing drop-offs.
Percentage-based and rule-based feature rollouts with user property targeting, cohort targeting, and multivariate A/B testing. Experiment results are automatically linked to analytics data for impact measurement.
Use Case:
Roll out a new checkout flow to 10% of premium users, automatically measure conversion rate differences against the control group, and gradually increase rollout based on statistical significance.
Managed data warehouse that syncs external data sources alongside PostHog event data. Supports batch exports and real-time data pipelines to external destinations. Free historical syncs.
Use Case:
Combine Stripe payment data with product usage events to analyze revenue per feature, identify which features drive upgrades, and build custom LTV models using SQL.
In-app surveys with targeting rules, branching logic, and integration with analytics data. Collect NPS, CSAT, and custom feedback tied to specific user segments or behaviors.
Use Case:
Trigger an NPS survey for users who completed onboarding last week, then correlate satisfaction scores with feature usage patterns and retention rates.
Dedicated tracking for AI feature usage including token consumption, latency, and model performance. PostHog AI provides credits for AI-powered insights and analysis within the platform.
Use Case:
Monitor your AI chatbot's response latency, token costs per conversation, and user satisfaction across different LLM models to optimize cost and quality tradeoffs.

We believe in transparent reviews. Here's what PostHog doesn't handle well:
The self-hosted version provides identical features to PostHog Cloud but requires you to manage infrastructure, updates, and scaling. Benefits include complete data control, no data transfer to third parties, and potential cost savings for high-volume applications. However, you need DevOps expertise for setup and maintenance. PostHog provides Docker and Kubernetes deployment guides, but you're responsible for backups, security patches, and performance optimization.
Yes. PostHog includes web analytics billed alongside product analytics events. It tracks page views, sessions, referrers, UTM parameters, and user paths. The key differences: PostHog gives you raw event-level data access via SQL, session replay integration, and no data sampling. However, Google Analytics has deeper SEO and advertising attribution features. Many teams use PostHog for product analytics and GA4 for marketing attribution.
Nothing breaks. If you haven't added a credit card, PostHog will pause data collection for that product until the next billing cycle. If you have a card on file, you'll be charged usage-based rates for overages. You can set hard billing limits per product — for example, cap session replay spending at $50/month — so you never get surprise bills.
PostHog offers EU-hosted cloud (Frankfurt data center), automatic PII masking in session recordings, cookie-less tracking options, and a consent management API. Self-hosted deployments give complete data sovereignty. PostHog is SOC 2 Type II certified, GDPR compliant, and HIPAA compliant for healthcare use cases. Session recordings automatically mask form inputs and sensitive data by default.
