Open source autonomous engineering harness in your cloud
Hand it a ticket. Get a draft pull request.
Ticket in, draft pull request out
Every task gets its own sandbox in your cloud. The sandbox holds placeholder tokens only; a proxy swaps in the real ones and allows writes only to your repos.
One shared harness for the whole engineering org
Staged, gated pipeline
Orientation, planning, plan review, implementation, self-review. No code is written until the plan passes review.
Closed feedback loop
Review comments, @mentions and failed CI runs route back to the running task.
Versioned memory
Learnings are distilled into your repo and land as a commit on the pull request, reviewed like code.
Credential isolation
Sandboxes hold placeholder tokens. An egress proxy injects the real ones and scopes writes to your repos.
Per-stage model routing
OpenAI or Anthropic, with model and reasoning effort set per stage. Your keys.
Self-hosted
Docker Compose or Kubernetes, one isolated sandbox per task.
We built it for our own engineering team
Our engineers have handed tickets to DevBox for six months. Read the story behind it.
