See your code as a 3D city.
DevCity AI turns any GitHub repository into an interactive city of buildings — each file scaled by complexity, colored by risk, and explained by AI.
Health, risk & tech debt — scored instantly.
Every repo gets an objective health score, a risk grade, and AI-written summaries you can ship to your standup.
This repo follows a clean modular structure. Two hot files in src/core/ account for ~38% of the risk — see suggestions on the right.
