Ship a container. Get a verdict.

Build a frontend and a backend, package them in one Docker container, push to GitHub and submit the repository. We build it, run it in a sandbox, drive it with a real browser and score what it actually does.

1 · Build

Any language or framework. One Dockerfile at the repo root, one port, one origin.

2 · Submit

Paste your GitHub URL. Private repos work with a read-only token.

3 · Judged

Network traffic is monitored at both the browser and the server, so only honest implementations pass.
