Devbox

Devbox is an open source autonomous coding system that plans, writes, and tests code from tickets.

Devbox is an open source autonomous engineering system that runs on your infrastructure. You hand it a ticket, and it plans the change, writes the code, runs tests, reviews its own work, and opens a draft pull request. It is built for a whole engineering team, working across your repositories and remembering what it learns. The system uses a staged pipeline with model routing for OpenAI or Anthropic models. It features credential isolation where sandboxes hold placeholder tokens while an egress proxy injects real ones. You can run it locally using Docker Compose or on Kubernetes.
