Quick Verdict — Score: 83/100
PostHog is the modern product analytics stack in one tool. The combination of analytics + session replay + feature flags + A/B testing in a single platform with a generous free tier makes it the default choice for startups. The open-source option with self-hosting provides data sovereignty that no proprietary competitor can match.
Who Is This For
Product teams who need actionable user behavior insights, developer-focused startups that value data ownership, growth teams running experiments with feature flags and A/B tests, and any company that wants to consolidate their analytics stack (replacing 3-4 tools with one).
Who Is This NOT For
Pure marketing teams that only need web traffic analytics (Google Analytics is simpler), companies with very simple analytics needs (<10K monthly users), or teams without technical resources for self-hosting (use their cloud option instead).
Pros
- +All-in-one platform replaces Mixpanel + LaunchDarkly + Hotjar + Typeform
- +Open-source core with self-hosting option = no vendor lock-in
- +Extremely generous free tier (1M events/month on cloud)
- +Active community and transparent product development
—Cons
- -Self-hosting requires DevOps knowledge and ongoing maintenance
- -SQL access is powerful but requires technical skills to leverage fully
- -Some enterprise features (SSO, audit logs) locked behind Scale/Enterprise plans
- -Documentation can lag behind rapid feature releases

Bottom Line

Start on the free tier, self-host when you need data sovereignty. It's one of the few tools where the free tier is genuinely sufficient for most early-stage products.
