Quick take

  • Analytics, session replay, A/B tests, feature flags, surveys, error tracking and email in one tool.
  • Free every month up to 1 million events and 5,000 replays, then you pay per use. No charge per team member.
  • PostHog AI builds charts and answers questions in your own words, and Claude Code can set it up through the wizard and MCP server.
  • Built for product teams. It's a lot of tool if you only want website visitor numbers.

What is PostHog?

PostHog shows you what people do inside your website or app. It records every click and page view automatically, then lets you build funnels (where people drop out of a sign-up or checkout), see who comes back, and watch replays of real sessions. The same tool runs A/B tests, feature flags (switching features on for some users), in-app surveys, error tracking and email.

PostHog AI answers questions about your data in your own words, builds the charts for you and can review session replays to find the moments you care about. There's an MCP server and a setup wizard, so Claude Code can install PostHog in your app and pull numbers into a chat.

The free tier is big: 1 million events, 5,000 replays and 1,500 survey responses every month, with no seat fees. The catch is that it's built for product teams. There are so many tools and settings that a small business owner who only wants visitor numbers may find Google Analytics or Clarity simpler.
