RepoMap: GitHub Infrastructure Diagrams

Turn any GitHub repo into an infrastructure diagram: services, databases, queues, third party APIs, and deploy targets.

RepoMap turns any GitHub repository into an infrastructure diagram in seconds. Open a repo, click Map infra, and see how the project fits together: the frontend, backend services, databases, caches, queues, file storage, outside APIs it relies on, and where it deploys. RepoMap reads the project’s configuration and dependency files to figure this out, and every item in the diagram links back to the file it came from, so you can check its work. You can export the diagram as an image or as Mermaid code to drop into your README, switch between horizontal and vertical layouts, and pan and zoom around large projects. It works on public repos out of the box, and on private repos if you add your own GitHub token. There’s no account, no AI, and no server. Everything runs in your browser. Useful for getting up to speed on a new codebase, understanding an open source project before contributing, or documenting your own work.
