PostHog
Open source product analytics platform for understanding user behavior.
PostHog is an open source product analytics platform that combines event tracking, session recording, feature flags, A/B testing and surveys in a single tool. It is used by SaaS teams to understand how users interact with their product and run experiments to improve it.
What it does
PostHog collects product events, records user sessions, manages feature flags for controlled rollouts, enables A/B testing and collects user feedback through surveys, all in one platform that can be self-hosted.
Who it is for
- Product managers and engineers at SaaS companies
- Growth teams running experiments and feature flag tests
- Startups that want to understand user behavior from day one
- Technical teams that want a self-hosted option for data privacy
Problems it solves
- Understanding where users drop off in the product funnel

When to use
Use PostHog when you want comprehensive product analytics with feature flags and experiments in one open source platform. Especially strong for technical teams that value self-hosting and data control.
Do not use PostHog for simple website traffic monitoring where a lightweight analytics tool would be more appropriate. Its strengths are in product analytics and experimentation, not marketing analytics.
