PostHog

PostHog is an all-in-one product analytics platform that combines analytics, session recording, feature flags, experiments, and surveys in one self-hosted or cloud-hosted package. The open-source version gives you complete code access and data ownership, perfect for engineers who want to understand and customize their analytics infrastructure. The free tier includes 1M events/month, 5K session replays, and all core features without per-seat costs.\n\nFor technical indie hackers, PostHog is exceptional because it solves the problem of tool fragmentation. Rather than stitching together Mixpanel + LaunchDarkly + Statsig + Hotjar, PostHog provides a unified platform. Self-hosting on a $5/month VPS is feasible, or use their cloud at $180–$900/month depending on volume. The transparent, event-based pricing means you only pay for what you use, with no hidden per-user fees.
