RepoVerse

Explore famous codebases as 3D cities

A file tree tells you what exists. It does not tell you what is large, what everything else depends on, or what nobody has touched in a year. RepoVerse turns a repository into a city so that shape becomes visible: folders are districts, files are buildings, height comes from lines of code, and git history decides how each building looks — recent work gets construction cranes, abandoned code weathers grey.

The metropolisSee every mapped repository at once, connected by what they depend on.→

Preact

JavaScript

preactjs/preact

The same shape as React drawn at a tenth the scale. One small core district holds the diffing algorithm, and the compatibility layer sits beside it as a separate quarter.

Vue

TypeScript

vuejs/core

Cleanly zoned: compiler, runtime and reactivity each occupy their own district, with narrow, deliberate roads between them.

FastAPI

Python

fastapi/fastapi

A metropolis where documentation outweighs the source. The library itself is a compact, tall core surrounded by sprawling tutorial suburbs.

Tornado

Python

tornadoweb/tornado

A web framework built around its own event loop, which shows: the networking core is a tight cluster, and the HTTP handling grows outward from it.

Flask

Python

pallets/flask

A small town rather than a city. Few buildings, all of them central — almost every file talks to almost every other one.

Express

JavaScript

expressjs/express

Flat and horizontal. A handful of core buildings surrounded by an unusually large district of examples.

Requests

Python

psf/requests

Famously small and tidy. A single main street, a dozen buildings, and almost no sprawl — the shape of a library that stayed focused.

Click

Python

pallets/click

A layered package structure that reads clearly from above: parsing, core and decorators stacked in visible tiers.

SWR

TypeScript

vercel/swr

Compact and modern. A few tall buildings of hooks logic with test districts mirroring them almost one to one.

Axios

JavaScript

axios/axios

A hub-and-spoke town. The core adapter sits at the centre and everything else radiates outward from it.

Gin

Go

gin-gonic/gin

A Go web framework with almost no vertical sprawl. The router and context types carry most of the weight, and nearly every building sits one level from the centre.

D3

JavaScript

d3/d3

A federation rather than a city — dozens of small, independent modules with surprisingly few roads between them.

Recently mapped cities

Public repositories someone already turned into a city. Each page is the city itself.

Scan your own repository

Any public GitHub repository works, and public scans need no account. Paste an address and the city is generated from the code itself — the same repository always produces the same city, so you can recognise your own project between visits.

Questions

What is a code city?
A 3D map of a repository: each file is a building, folders are districts, and git history lights recent work. It is generated from the source, not drawn by hand.
Do I need an account?
Not for public GitHub repositories. Private repos need a GitHub login and Pro.
How do I share a city?
Every mapped repository has a public URL of the form /city/owner/repo, with a preview card for X, Slack, and iMessage.
