  • $20,000 in credits

    One-time. Spend it on coding agents, data analysis, computer use, or app generation.

  • A full machine for your agent

    Shell, filesystem, network, and an optional desktop. One isolated microVM per session.

  • Works with any agent stack

    Any model, any framework. The runtime is Apache-2.0, so there is no lock-in.

  • Custom sandbox CPU and RAM

    Pick the CPU and RAM per sandbox. The default is 2 vCPU and 4 GiB.

  • 100 concurrent sandboxes

    For parallel agents, evals, and test runs. Expandable to 1,100 with an add-on.

  • Sessions up to 24 hours

    Long tasks stay alive. Pause a sandbox for free and resume it from the same state.
