About

PostHog is an open-source product-analytics platform that also covers session replays, feature flags, A/B tests, and surveys. Its API and SDKs let you capture events, identify users, and run experiments. The cloud free tier is generous enough for small sites and MVPs, and you can self-host the open-source version too. One entry here covers analytics and surveys together.
