Let the agent test against the real database

Every Compute has Docker Engine with compose and sudo. Run Postgres, Redis and the rest of your stack beside Claude Code or Codex and watch it test against the real thing. From $39 a month.

Your agent tests against mocks, and staging finds the bugs

The agent can't start Postgres, Redis or the queue, so it writes the feature against stubs and calls it done. The code meets the real stack for the first time on staging.

A cloud sandbox without Docker can't run your compose file. On your Compute it starts beside the agent.

One feature against the full stack

  1. 14:00

    compose up

    Your docker-compose.yml starts the way it does on your laptop. Bind the database's data to the project folder and it outlives the terminal.

  2. 14:02

    Hand the agent the feature

    It reads the container logs, runs the migrations and hits the real services.

  3. 14:40

    Integration tests go green

    Forty-six tests pass against the real Postgres, Redis and Meilisearch.

  4. 14:41

    Click through it

    The app answers at its preview URL over HTTPS, and the containers keep running in that terminal for tomorrow.

Tests against the live stack

  • Full Docker, ready at login

    Docker Engine and the compose plugin, your user in the docker group, sudo for everything else.

  • Services that outlive the session

    Containers keep running after the tab closes. Tomorrow's run in the same terminal starts with a warm database.

  • Room for the data you keep

    Images and build cache live in the terminal. Your projects, seed data and bind-mounted databases sit on the account disk: 50 GB on Start up to 1,000 GB on Business Ultra.

  • Your services, in the browser

    Web services answer at their preview URL over HTTPS; database tools run in the terminal right beside them.

The size for this job

Pro's 8 GB hold a database, a cache, a search engine and the agent at once.

Questions about this

Is it real Docker?

Yes. Docker Engine runs inside each terminal, an unprivileged system container with nesting on. docker, docker compose and your images work the way they do on any Linux server, at the lowest CPU and disk priority, so your shell and agent stay responsive during builds.

Can containers reach the internet?

Yes, at your size's speed for each terminal: 50 Mbit on Start up to 1,000 Mbit on Business Max and Business Ultra. Private networks and outbound mail on port 25 are blocked for every customer.

Do images count against my disk?

No. Images, volumes and build cache live on the terminal's own disk and go away when you end it. Only what you keep in your projects and home folders counts against the account disk.
