Analytics and monitoring decision

Crazy Egg

A competent developer can build a narrow self-hosted replacement for core heatmaps/recordings/A-B testing over several weeks, but you lose enterprise polish, AI analysis, long-term scalable ingestion/storage, and vendor compliance/SLAs — for full feature parity it’s cheaper to keep paying.

Open-source builds that already do this

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Crazy Egg alternatives, with the arithmetic →

What a replacement has to do

  • Collect pageview and interaction events from a small script, store and aggregate events to generate heatmaps, capture sampled session recordings and serve playback, run a basic client-side A/B splitter and collect conversion events, provide a dashboard to view heatmaps/recordings and basic experiment results.

What it still won’t have

  • Enterprise features (SAML SSO, SLA, dedicated support)
  • Large-scale storage, ingestion reliability and multi-tenant scaling
  • Built-in AI analysis and export-to-AI features
  • Export connectors, add-on marketplace and polished production UX
  • Compliance paperwork and formal DPA handling managed by vendor

What remains hard

  • Brand trustTrusted by over 449,000 websites worldwide
  • Compliance and regulationwe follow industry-standard security practices and comply with major privacy regulations such as GDPR and CCPA.

Runnable build prompt

Not run yet
Build a minimal self-hosted Crazy Egg clone using Node.js (Express) backend, Postgres for events/metadata, S3 for recording blobs, Redis for short-term session state, and a React frontend. In scope: a JS install snippet, event ingestion API, sessionization and sampling, heatmap aggregation (count clicks/positions per page and render overlay tiles), session recording storage and a playback UI, a basic A/B test assignment client and conversion tracking, and a dashboard to view heatmaps/recordings and experiment summaries. Out of scope: multi-tenant billing, enterprise SSO, advanced AI analysis, and production-grade autoscaling. Include error handling, input validation, unit and integration tests, and a README with deployment steps (Docker Compose and a low-cost cloud VM + CDN configuration).

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
