What the free edition leaves out

The free edition is genuinely usable, but some team or enterprise features need a paid plan. “Not confirmed” means the official pages we read did not say, so we do not guess.

Best for

Product and engineering teams that want analytics, replay and feature flags in one tool, mostly on PostHog Cloud.

Why choose it over Mixpanel

The repository is MIT licensed apart from the ee directory, and a free Docker deployment is available if you want the data on your own server. One product covers analytics, session replay, feature flags and surveys, so you do not stitch several tools together.

Where it falls short

PostHog's own disclaimer says everything runs on one machine, is unlikely to scale past a couple of hundred thousand events, and that paid-plan features are Cloud-only. SSO enforcement, SAML, RBAC and audit logs are excluded from self-hosting, and PostHog gives no support for self-hosted instances. For most companies the project itself recommends PostHog Cloud.

Open-source alternative to

  • Mixpanel — PostHog can replace Mixpanel for product analytics such as events, funnels and retention.
  • Amplitude — PostHog can replace Amplitude for product analytics and experiments.
