All-in-one product analytics platform with built-in feature flags, A/B testing, session replay, and surveys.
PostHog is an open-source product analytics platform that includes feature flags as part of a broader suite of product tools including analytics, session recordings, A/B testing, surveys, and data pipelines. This integrated approach means teams can flag features, run experiments, and analyze results all in one platform without stitching together multiple tools.
PostHog's feature flags support boolean and multivariate variants, percentage rollouts, and targeting based on user properties, cohorts, and custom groups. The platform evaluates flags locally using its SDKs for fast performance, with the option to bootstrap flags for instant evaluation on page load.
With a generous free tier covering 1 million feature flag requests per month and transparent usage-based pricing beyond that, PostHog is popular with startups and product-led growth companies. The platform can be self-hosted or used as a managed cloud service, and its open-source nature means full transparency into how your data is handled.
