For developers just starting out, PostHog is a free way to understand how your product is being used, without having to send any data to 3rd parties.

For enterprise customers, one data security becomes a key concern, or B2C businesses where using a SaaS solution is unaffordable, it's typical to see teams hosting an event capture platform, a data lake, and sophisticated analytics tools. The end result is that data scientists are needed and most developers don't have easy access to product intel. PostHog solves that gap - it lets everyone understand how your product is being used, without having to send data to 3rd parties, even once you have scaled to millions of visitors.

It has a JS snippet that can autocapture events, and pre-built libraries to push backend data to. Build up full user histories, visualize product trends, funnels, and run experiments with new features.

  • Experiment QA Checklist โ€” 27 pre-launch validation items across 7 categories, with optional auto-audit when you connect Optimizely
  • Stats Method Picker โ€” five questions to a stats-engine recommendation
  • Test Prioritization Scorer โ€” rank a backlog of test ideas
