A GitHub Skyline alternative that stays live
GitHub Skyline turned a year of contributions into a 3D model you could look at or print. If you want something that keeps updating, Caldera turns your repos into a living city: each repo is a building, this week's work lights the windows, and your page refreshes from GitHub on its own.

Snapshot versus living view
A skyline model is a snapshot of one year of contribution counts. A Caldera city is per repo and keeps changing: it rebuilds from GitHub every 6 hours, the sky follows the viewer's time and weather, and live events (visitors to your sites, your coding agents) appear as they happen.
What you can do with a city
- Share it: every city has a link preview image for X, LinkedIn and chat apps.
- Embed a badge in your README that opens it.
- Pop it out into a small window and keep it on screen all day.
- See it next to everyone else's on the World map.
Make one now
- Open caldera.social/gh and enter your username for an instant preview.
- Click Claim it with GitHub to turn the preview into your own live city.
Questions
Can I print my Caldera city?
Not as a 3D file today. You can share it, embed it and pop it out on screen.
Is it per year or per repo?
Per repo: building height reflects that repo's commits over the last year.
Does it need any install?
No. Sign up with GitHub in your browser.
Is it free?
Yes.
