Agent sandboxes

Agent sandboxes are isolated compute environments where coding agents can safely run commands, install dependencies, and execute generated code.

  • Kubernetes-native isolation for autonomous agents.

    Free and open source; Kubernetes infrastructure extra

  • One container for an agent's browser, shell, files, and IDE.

    Free and open source; infrastructure extra

  • Persistent microVMs that scale to zero between agent turns.

    Up to $200 credits; $0.0000115/GB RAM-sec + $0.20/GB-mo snapshots

  • Persistent Linux computers for agents and developers.

    $20/mo minimum usage; per-second billing; stopped boxes free

  • Isolated Linux environments controlled from Workers.

    Workers Paid $5/mo; Containers CPU, memory, disk, and network metered

  • Firecracker computers that pause with their full state.

    500 introductory credits; $0.0504/vCPU/hr + $0.0162/GiB RAM/hr

  • Persistent cloud sandboxes for coding agents.

    $200 introductory credit; then $0.0504/vCPU/hr + $0.0162/GiB RAM/hr + storage

  • Instant Linux microVMs for untrusted code.

    Pre-release; no separate public Sandbox price listed

  • Run coding agents in local microVMs.

    Preview; included under the applicable Docker Desktop subscription

  • Purpose-built cloud computers for AI agents.

    Hobby free + one-time $100 credits; Pro $150/mo + usage

  • Fast isolated VMs from any OCI image.

    $50 introductory credits; $0.04/hr for 1 vCPU + 1 GB RAM

  • Local microVMs for untrusted agent workloads.

    Free and open source locally; cloud private beta from $49/mo

  • Elastic isolated compute for production agent systems.

    $30/mo free compute; $0.00003942/core-sec + $0.00000667/GiB-sec

  • A policy-controlled runtime for autonomous agents.

    Free and open source; infrastructure extra
