what is agentcity fr?

Agentcity turns your history of working with AI coding agents into a persistent, pixel art city that lives entirely on your own computer. Every repository you work on becomes a building, and the more shipped work you put into that repo, the more floors and upgrades that building gets, growing from a simple tent up through a hut, house, workshop, tower, and eventually a landmark. The kind of work you do, such as writing code, tests, infrastructure, or research, shapes what district and style a building takes on, and roads between projects widen the more you move between them. The city is generated deterministically from your local agent activity log plus a seed value you choose, meaning the exact same history and seed will always produce the exact same city, with no separate save file needed. Different seeds produce different landscapes such as rivers, coasts, or hills, so no two people's cities look alike even with similar work. When you first launch it, agentcity reads your existing agent history and replays it as a sixty to ninety second timelapse showing your city grow from its first building to today, so returning users do not start from an empty field. Everything runs locally by default: there are no accounts, no telemetry, and no network calls unless you explicitly export something like a snapshot image. You can pan, zoom, and rotate the isometric camera, scrub back and forth through your city's full history, and hover over any building to see its repo name, tier, and work mix. An optional federation feature lets a team opt in to share a combined skyline on something like an office screen, but even then only privacy safe summary facts are sent, never raw commands or file paths. The tool is run with a single command using npx, and there is also a demo mode with simulated activity for anyone without existing agent history yet. It is built in TypeScript for Node 20 or later with no runtime dependencies, and the entire visual renderer is one self contained HTML file using canvas drawing rather than any framework. The project describes itself as early and actively evolving, with the solo version already usable daily.
