MetriBee is a free, open-source, self-hosted dashboard for the GA4 data you already have. Start one Docker container on a laptop, home server, Raspberry Pi or small VPS, add a read-only service account, and open every GA4 property on one calm screen. There is no new tracking script and no event database of your own—Google stores the events; MetriBee is a small stateless process.

The multi-property home offers Cards, Status, Table and Heatmap views with CSV export and optional AdSense earnings. Realtime uses the GA4 Realtime API for every property, with spike detection and a live 3D globe. Funnels, journeys and retention are built on GA4 native funnel reports, page paths and first-visit cohorts. Reports include Overview, Pages, Events, Journeys, Retention and Funnels with click-to-filter and period comparison. Search Console metrics can sit beside GA4. Embed widgets, share revocable private dashboards, query via MCP at /mcp, stay inside GA4 API quotas, and press P to blur site names. Demo: docker run --rm -e DEMO=1 -p 127.0.0.1:5483:5483 ghcr.io/nexmoe/metribee:latest. MIT backend; AGPL-3.0 frontend adapted from Rybbit.

Why it exists: GA4 already stores your events for free; MetriBee replaces the interface and keeps the storage. No analytics warehouse to pay for, no ClickHouse or PostgreSQL to maintain, and no migration—years of history appear on day one, and stopping MetriBee leaves data in GA4.

Compared with Rybbit, Umami and Plausible CE (public docs, October 2026), MetriBee runs as one Node process with no event storage on your server, keeps your existing GA4 tag, and adds multi-site layouts, spike detection, a live globe, retention cohorts, embeddable widgets and MCP. Others win on session replay, web vitals, owning raw events, or cookieless tracking.

FAQ: do not change your tracking script; data stays in GA4 with short-lived caches; DEMO=1 works without Google (8 fictional sites); no built-in login—use localhost, Cloudflare Access or Tailscale.
