The Git Observatory
GitHub charted as a night sky. Every star is a real star
The Observatory turns GitHub into an astronomical instrument. Tonight's fastest-rising repos become the brightest stars. Repos that suddenly explode get real supernova designations (SN 2026-07-14A) with Δ-magnitudes calculated the way astronomers do it. Point the telescope at any month back to 2008, get a stellar classification for any repo (Protostar → Hypergiant), or see your own GitHub account drawn as a constellation. 100% client-side, $0 to run, no signup, no tracking.
Hey Product Hunt! 👋 The Observatory started as an experiment — "what if GitHub trending looked like the night sky?" — and turned into a full astronomical instrument.
My favourite part is what it doesn't have: no backend, no database, no AI APIs, no tracking, and no signup. It costs $0 to run — everything happens in your browser against GitHub's free API. Even the natural-language search is a hand-written parser.
Things to try first:
⭐ Type your GitHub username into "Your Sky" — your repos, drawn as a constellation
💥 Check Supernova Watch — repos detonating 10×+ above their lifetime average, with real astronomical designations
🔭 Point the Telescope at the month you started coding
For the engineers asking "wait, how?" — Field Notes documents every trick: gitobservatory.com?notes=open
I'd love to hear what constellation you find!

Who hunted The Git Observatory?
The Git Observatory was hunted by Rakesh Kusuma. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
