Your git history, replayed as a city
See your repository grow, one commit at a time
gitropolis turns your git history into a living 3D city. Files become buildings, folders become districts, and each commit adds to the skyline.
How it works
From repo to city in three steps
- 1
Submit a public repo URL
Paste a github.com/owner/repo link below. No install, no auth beyond the repo being public.
- 2
We analyze its full history
Every commit is processed to reveal how the code evolved, transforming the repository into a visual city.
- 3
Press play and watch it grow
Scrub through time, speed up to ×30, and see construction land in colour as PRs merge.
How to read a city
Every building tells you something
Height — lines of code
Taller buildings hold more code, damped logarithmically so a 40-line file and a 1,200-line file both stay readable side by side.
Districts — top-level directories
Each top-level folder gets its own stable colour and ground plate, so the shape of the repository reads at a glance.
Construction colour — commit type
When a pull request lands, its buildings flash the colour of the conventional-commit type behind it; anything unrecognised falls back to a quiet neutral grey.

Add a repository
Submit a public GitHub repo to create its city. Processing can take a few minutes depending on the repo's history — submit it and come back later, no need to wait here.
