Best Product Analytics Tools
PostHog is the best product analytics tool for most product teams in 2026: the broadest free tier, published per-unit prices with billing limits, and analytics, replay, flags, experiments and surveys on one data set. Pick Mixpanel for fast self-serve reports with SSO on a published plan, or Amplitude for 2M free events and low mid-volume pricing.
PostHog alternatives
Switch to Mixpanel if your product managers want a simpler analytics tool with one meter. Pick Amplitude if you want to replace most of PostHog with a single vendor.
