how it works

Talks to your datasource.
No image plugin. No cloud.

Observatory doesn't scrape Grafana screenshots. It reads the panel's query, sends it to your datasource via Grafana's own /api/ds/query, and renders the result with Swift Charts — same data path your browser uses, but native and GPU-accelerated.

Service account tokens, stored in a local JSON config.
Template variables resolved from the dashboard + your overrides.
Nothing leaves your Mac except the query to your own Grafana.

what's inside

Built for developers who already have a Grafana.

Observatory is a small, opinionated companion — not a Grafana replacement. It does one thing well: put the metrics you already watch on your desktop, native and fast.

Native SwiftUI Charts

Every sparkline is drawn with Apple’s Swift Charts. GPU-accelerated, crisp at any size, no PNGs, no iframes, no blurred screenshots.

Pick any panel

Browse every dashboard in your Grafana. Check any panel — the query, datasource and unit snap into a widget slot. No YAML, no config files.

Three widget sizes

Small, medium, and 2×2 large. The configurable widget lets you pick up to four panels per instance from your favourites.

Self-hosted only

Point it at your own Grafana. Your service account token lives on your Mac. The only network call it makes is to you.

Legit TLS required

HTTPS with a real cert, or HTTP on your local network. No self-signed circus, no custom trust stores, no support-ticket rabbit holes.

Signed + notarized

Developer ID code signed and notarized with Apple. Hardened runtime on. Open it, run it, add it to the Dock.

tour

Five steps from "just installed" to "always watching".

step 01

Your Grafana, one pane.

Paste the URL, a service account token and your datasource UID. Observatory lists every dashboard, grouped by folder, with badges for panel type.

step 02

Four slots per widget.

Every large widget has four panel slots. Small renders slot 1, medium slots 1–2, large is a 2×2 grid. Pick any mix.

step 03

Pick any panel you’ve favourited.

Stars in the dashboard browser add panels to your favourites. They show up as dropdown options in every slot — CPU Basic, RAM Used, Sys Load, Network Traffic…

step 04

Three native sizes.

Observatory registers small, medium and large widgets with macOS. Drag any of them from the standard widget gallery, just like Weather or Calendar.

step 05

Always on your desktop.
