How pricing works
These two tools don't price the same way, so the headline numbers below aren't directly comparable until you plug in your own volume.
- PostHog (Per Usage) — PostHog bills purely on usage — Free up to 1M events/mo, then usage-based. There is no fixed per-seat fee, so the monthly cost depends entirely on how much you consume.
- Statsig (Unknown model) — Statsig bills on a fixed plan from $150/mo, so the listed price is what you pay regardless of volume.
Per-minute, per-credit and per-token rates exclude any downstream model, speech or telephony costs unless the vendor states otherwise.
Open-source product analytics + feature flags + session replay + surveys, positioned as the all-in-one alternative to Mixpanel + LaunchDarkly + FullStory + Typeform. Distinctive for self-hostable free tier (unlimited events on your infra) and its "we're the open-source everything" positioning. Cloud priced free-$450+/mo based on events + recordings. Popular with technical founders who don't want to stitch 4 tools together and prefer OSS over vendor lock-in.
Product experimentation + feature flags + analytics platform, founded by ex-Facebook product infrastructure team. Positioned as the alternative to LaunchDarkly + Amplitude bundled — flags AND experimentation AND analytics on one platform. Distinctive for statistical rigor (built on the same experimentation framework Facebook uses internally). Free tier includes 1M events/mo. Pro $150/mo. Popular with product-led-growth teams that run continuous A/B tests as core practice. Acquired by OpenAI in 2025.

What each is best for
PostHog is worth it if… product/growth teams that want product analytics + session replay + feature flags + A/B testing + surveys in one open-source platform — particularly if you value self-host option and pay-as-you-go pricing. Free tier includes 1M events + 5K replays/mo; pay-as-you-go beyond; add-ons for SSO/security/data warehouse.
Statsig is worth it if… growth-stage product teams (10-100 engineers) that need feature flags + A/B testing + product analytics in one platform — particularly if you value modern developer UX and open-source SDKs. Free tier covers small teams (1M events + 5K flag checks); Startup adds more capacity; Enterprise custom.
Bottom line: Similar positioning, closer to a preference call than a strategic one.
