How it runs

Four steps, one room.

  1. 1

    [step 1/4]

    Spec

    Before any work, the room asks for whatever your brief is missing, in one message, and confirms the plan.

  2. 2

    [step 2/4]

    Implement

    Every action streams into the transcript as it happens. Reply at any time to steer.

  3. 3

    [step 3/4]

    Test

    Files are handed over the moment each one is finished, so you can react before the final pass.

  4. 4

    [step 4/4]

    Docs

    Finished files are handed over as Repo, OpenAPI and Docs, with a line on what each one contains.

Missing something? The room asks for it once, in a single message.

Inside the room

  • Code sandbox
  • Test runner

Plus a private Linux sandbox with Python, a file system and web access.

  • Billed per second

    $0.0106 a second while the room is open. No minimum.

  • You can steer

    Reply at any point. The room adjusts mid-run instead of starting over.

  • Nothing is kept

    Check out and the room, its sandbox and your uploads are deleted.
