Honest comparison

Webrec vs PostHog

The open-source product analytics suite.

PostHog bundles product analytics, feature flags, A/B testing, and session replay into one broad platform. Webrec takes the opposite approach: replay is the core product, not one module among many, so the replay, heatmap, and debugging experience gets the full attention.

A Webrec replay: the timeline, frustration markers, and devtools in one view.

Where Webrec leads

  • Replay-first design: devtools, frustration signals, and heatmaps are the core product
  • Replay-derived heatmaps with page snapshots built from real sessions
  • Flat monthly plans rather than per-event usage pricing
  • Session data hosted on UK infrastructure, useful for UK data residency requirements
  • Lighter integration surface: one SDK, one script tag

Where PostHog may fit better

  • Feature flags, A/B testing, and a data warehouse in the same platform
  • Product analytics at very large event volumes

Bottom line: Both products are open source and self-hostable, which is rare in this space. Choose PostHog when feature flags and experimentation matter as much as analytics. Choose Webrec when session replay is the job to be done and you want it done deeply, with UK data residency on the hosted plan.
