RepoWorld

A visual IDE you can walk through. Paste a GitHub repo and it becomes an explorable voxel city — every file a building, every directory a neighborhood, every open issue a monster roaming the streets.

Then you fight back: aim at a bug, deploy Greptile , and watch it hunt the thing down. When it lands, you get the real issue, a proposed fix, and a plain-English explanation of why the code was broken.

Codebases are invisible. You can read a file, but you can't see a system — where the weight sits, which corners are rotting, what depends on what. Repo World makes a repository a place , so understanding it becomes navigation instead of archaeology.

That framing does something a file tree can't: it makes problems physical . A neglected module isn't a row in a backlog, it's a building with a monster outside it and a red beam of light you can see from across town.

Every placement is deterministic — seeded from file paths, never Math.random() — so the same repo always produces the same city. Walk away and come back, and your landmarks are where you left them.

Bugs carry red beacon columns visible from anywhere in the city. Green beams mark Greptiles, gold and blue mark quest-giving NPCs. Navigate by light.

Put your crosshair on the bug — or anywhere on its beam — and press E . The nearest idle Greptile in the roaming pack is dispatched and stomps across the city toward it.
