Your apps POST their numbers — active users, messages per minute, signups, p95 latency. You pick what matters and watch it live on one page built to sit on a wall display.
# emit a live number from anywhere in your app. curl -X POST https://your-host/api/v1/metrics \ -H "X-API-Key: acme_prod_…" \ -d '{"name":"active_users","value":52,"instance":"web-1"}' # → 200 OK · upcheckr recorded it. # → it's on the wall, live.
Real numbers pushed in real time — thresholds coloring the bars, per-instance stacked & overlaid breakdowns, all on one page.
POST a name, a value, an instance. No exporters, no scraping, no agents to babysit — just an HTTP call from code you already wrote.
Pick the numbers worth watching and how they roll up — summed, averaged, or last-value — across every server reporting in.
One opinionated page, updating live. A single self-contained binary with SQLite inside — run it anywhere and point a display at it.
