Product analytics that don't lie
Funnels, retention, paths, lifecycle — all built on raw events you actually own. No sampling, no aggregated hand-waving, no “trust us, the dashboard is right.”

How engineers build better products.
PostHog is the open-source all-in-one platform for product analytics, session replay, feature flags, A/B tests, and the surveys you keep meaning to send. Built by engineers who got tired of stitching together six SaaS dashboards that all charge per-seat for the privilege.

What's in the box
Every analytics tool a product engineer actually needs.
One database, one billing line, one set of definitions for what an “active user” is. Hover any card to flash the hidden brand orange — DESIGN.md §1 calls it the signature interaction surprise.
Watch what your users actually did
Session replay with console logs, network requests, and the rage clicks your support team have been complaining about all week. Privacy masking on by default.
See a session →Feature flags & A/B tests
Ship a flag in five minutes, run an experiment in five days, kill the bad arm in five seconds. Same data warehouse as your analytics — the results never disagree with the funnel.
Roll one out →Self-host or hosted
Two clicks from zero to first event.
Drop us your work email and we'll send the install
command that fits your stack — npm,
pnpm, pip, go get,
or one truly heroic curl | bash. No
calendars, no “quick chat” bookings.
