PostHog
Open-source product analytics, session replay, feature flags, and experiments bundled, not sold separately.
What is PostHog?
PostHog is an open-source product analytics platform that bundles product analytics, session replay, feature flags, A/B experiments, surveys, a data warehouse, and LLM analytics into one tool you pay for usage-based. The same event you ingest powers every product, so you are not paying Amplitude, FullStory, LaunchDarkly, and a CDP separately. It is MIT-licensed and self-hostable for teams that need the data in their own VPC, and the cloud version is split between US (Virginia) and EU (Frankfurt) regions for residency requirements.

Use cases to evaluate
Bundling product analytics, session replay, and feature flag rollouts for an early-stage SaaS without juggling four vendors
Self-hosting the entire stack in an EU VPC for a regulated industry that cannot ship event data to US cloud vendors
Running A/B experiments tied to feature flags and watching session replays of users in each variant
Tracking LLM traces, generations, and evals for an AI feature using the same platform that already has product analytics
Fit to evaluate
Engineering-led startups and scaleups that want one bill instead of five
Open-source-friendly teams with compliance or data-residency requirements
AI product teams that need LLM analytics alongside traditional product metrics
Companies migrating off the Amplitude plus LaunchDarkly plus FullStory stack to cut cost
Business fit
Right for you if you are a developer-led team that wants analytics, replay, flags, and experimentation under one bill and one SDK install, or if you need to self-host for compliance. Skip if your stakeholders are non-technical marketers who want polished SQL-free dashboards and white-glove onboarding, since PostHog is built for builders first.
