PostHog

PostHog is a product engineering platform that brings product and web analytics, Session Replay, heatmaps, feature flags, experiments, surveys, error tracking, data warehousing, CDP capabilities, and AI tools into one system for building and improving digital products.

1. Product insight: teams can analyze funnels, retention, paths, user behavior, and website traffic, then move into session recordings and heatmaps to investigate the individual experiences behind quantitative trends.
2. Release workflow: feature flags and experiments connect behavioral measurement with controlled rollouts and A/B tests. PostHog also offers no-code A/B testing, allowing teams to test some changes without implementing every variant directly in application code.
3. AI and data: PostHog AI can work across product analytics and broader platform context to answer questions, create analyses, find relevant replays, and work with SQL. Its context warehouse can combine PostHog product signals with data from more than 120 external sources and destinations, including Stripe, Postgres, and HubSpot.
4. Commercial considerations: PostHog uses usage-based pricing with separate monthly free allowances for its products. Current free tiers include 1 million Product Analytics events and 5,000 Session Replay recordings, alongside separate allowances for feature flags, surveys, warehouse rows, error tracking, AI, and other products.

PostHog is particularly relevant to product engineering teams that want analytics, experimentation, debugging, customer data, and AI context available within the same platform instead of assembling and synchronizing several independent developer tools.
