Sandboxes for coding agents

A coding agent works for hours, keeps files between steps and often needs to go back to an earlier state. 15 providers listed here have no session limit, including Agent37 Cloud, Beam Sandboxes and Blaxel.

What a coding agent needs

Four things to look for in the table below

  • Long sessions

    Builds and test runs take time. Look at the session limit and the idle timeout.

  • Files that stay

    The repository and installed packages should still be there after a pause.

  • Snapshots

    Save a working state and return to it when a change breaks the build.

  • A real machine

    Git, Docker and a shell inside the sandbox, as on a developer's laptop.
