PostHog Has a Free API You're Not Using

PostHog is an open-source product analytics platform. Most teams use it for pageviews — but PostHog ships feature flags, A/B testing, session replay, and surveys in one tool. The Free APIs You're Missing 1. Feature Flags — Runtime Configuration Toggle features per user, group, or percentage. Evaluate flags server-side or client-side with automatic analytics. 2. A/B Testing — Built Into Feature Flags Create multivariate experiments. PostHog tracks which variant converts better automatically. 3. Custom Events — Track Anything Capture purchase completions, search queries, feature usage — any user action with custom properties. 4. Group Analytics — B2B Product Analytics Track metrics per company, workspace, or team. Understand how organizations use your product. 5. HogQL — Custom Analytics Queries Full SQL over your analytics data. Build custom dashboards and reports without data warehouses.
