Product analytics, session replay, and feature flags in one platform.
What It Does
PostHog is an open-source product analytics suite that combines event tracking, session recordings, feature flags, A/B testing, and funnels. You instrument events in your app and get deep insight into how people actually use your product.
Why Solo Builders Use It
One tool replaces analytics, session replay, and feature flag services
Generous free tier — 1M events and 5K recordings per month
Self-hostable if you want full data control
Autocapture means you get useful data before writing any tracking code
Pricing
Free up to 1M events/mo and 5K session recordings/mo. Pay-as-you-go after that. Genuinely free for most early-stage products.
Verdict
The best analytics platform for solo builders who want real product insights without stitching together five different tools.
Pros
Free tier is absurdly generous for small products
Session replay alone is worth the setup
Open source with a self-host option
Cons
Learning curve is steeper than simple analytics tools
Can be overwhelming — you don't need all the features on day one
Alternatives
Plausible — simpler, privacy-first, just web analytics
Mixpanel — similar product analytics, less all-in-one
