Comparison notes

PostHog provides session recordings, heatmaps, and product analytics in a self-hosted OSS package (source-available core, AGPL). OpenReplay is an OSS session recording and co-browsing platform with self-hosting support, providing comprehensive recording with DevTools-level detail. rrweb is the underlying OSS library that powers many session recorders. The main gap: Hotjar's in-session feedback widgets (polls, surveys embedded in recordings) are available in PostHog but less mature in OpenReplay. Self-hosting session recordings requires significant storage and retention policy planning for high-traffic sites.

Migration tips

  • Download existing Hotjar recordings before migrating — recordings cannot be transferred but key clips can be saved
  • Install PostHog or OpenReplay alongside Hotjar before full migration to collect parallel recordings for comparison
  • Recreate Hotjar feedback widgets and surveys in your OSS tool's equivalent feature
  • Configure session recording sampling rate in your OSS tool — recording 100% of sessions is storage-intensive for high-traffic sites
  • Update your privacy policy to reflect the new session recording provider and any differences in data handling

FAQ

Can I fully replace Hotjar with an OSS tool?

Feature parity varies. Most OSS alternatives cover 70-90% of core workflows, but may lack polish, integrations, or specialized features. Pilot the alternative with a subset of your team before fully committing.

What's the cost of self-hosting?

Plan for ~$5-50/month in VPS costs (DigitalOcean, Hetzner, etc.) plus 2-8 hours/month in maintenance. For a team of 20+, self-hosting usually breaks even against SaaS pricing within 6-12 months.

Which alternative should I pick?

Sort by GitHub stars (a proxy for community health), check the last-pushed date (avoid unmaintained projects), and read recent issues to gauge responsiveness.
