What is PostHog?
Open source product analytics platform with events, funnels, session replay, feature flags, and experiments. PostHog is useful for teams replacing several product growth tools while keeping the option to self-host sensitive behavioral data.
PostHog is worth evaluating if you need an open source option for analytics teams. The most important questions are whether it matches your workflow, whether the license fits your use case, and whether your team wants a hosted product, a self-hosted deployment, or both.
