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.
- Amplitude (Unknown model) — Amplitude bills on a fixed plan from $49/mo, so the listed price is what you pay regardless of 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.
Per-minute, per-credit and per-token rates exclude any downstream model, speech or telephony costs unless the vendor states otherwise.
The enterprise product analytics platform, publicly traded (AMPL). Positioned as the alternative to Mixpanel for product teams that need advanced funnels, cohorts, and predictive analytics at scale. Distinctive for its 'North Star' methodology framework that many product-led-growth companies now use as their operating rhythm. Free tier limited; paid custom based on tracked events — Growth typically $50-200/mo entry, enterprise deployments run $48K-100K+/yr. Real cost bloat: tracked event volume compounds fast.
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.

What each is best for
Amplitude is worth it if… Amplitude is the product analytics tool for product teams that need behavioral cohorts, funnel analysis, and retention charts to guide roadmap decisions. Plus starts usage-based scaling per event; Growth is where enterprise features live.
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.
Bottom line: Similar positioning, closer to a preference call than a strategic one.
