AIO Sandbox alternatives

Answer in brief

The 5 alternatives below are grouped by kind of sandbox, and each says what it does differently from AIO Sandbox. Start from whatever made you look: missing GPUs, session limits, self-hosting, pricing or isolation.

By the Agent Sandboxes editors · Updated

Why teams look beyond AIO Sandbox

A convenient batteries-included environment image for agents, best treated as a workload to run inside a stronger isolation layer.

  • Container-level isolation only, and the documented run command sets seccomp to unconfined
  • No snapshots, pause/resume or built-in orchestration; one container is one sandbox
  • Services are open unless an API key is configured
  • The maintainer is identified only as the "Agent Infra team" in the repository; corporate ownership is inferred from ByteDance's open-source channels and Volcengine's hosted listing

AIO Sandbox alternatives, by kind

Hosted sandbox platforms

SDK-driven sandboxes you create, run code in and destroy through an API.

  • E2B

    Open-source cloud sandboxes for AI agents, each a Firecracker microVM, with pause/resume, snapshots and forking.

    • Firecracker microVM
    • Open source
    • Self-hostable
    • BYOC
    • Pause/resume

    How it differs: Code interpreters and short-to-medium-lived agent tasks that need microVM isolation, with an open-source self-host path. The safe default for most agent builders: mature, open source, microVM-isolated and widely supported.

Browser and desktop sandboxes

Hosted browsers and full desktops that computer-use agents click, type and browse in.

  • Cua

    Open-source computer-use infrastructure: Linux sandboxes as gVisor containers and macOS or Windows sandboxes as VMs, run locally, in your own cloud account or as shared "Spaces".

    • gVisor container or VM
    • Open source
    • Self-hostable
    • Pause/resume

    How it differs: Teams that want open-source computer-use sandboxes on their own Macs, servers or cloud accounts, including macOS VMs on Apple silicon. The broadest open-source option for computer-use sandboxes across macOS, Linux and Windows, now firmly a self-run toolkit after the hosted cloud shut down.

Open-source runtimes to self-host

Open-source sandbox runtimes you run on your own servers or Kubernetes.

  • OpenHands Runtime

    The sandbox layer of the OpenHands agent SDK: an agent server that runs in a Docker container, in-process locally, or on the hosted OpenHands Runtime API.

    • Docker container
    • Open source
    • Self-hostable

    How it differs: Running OpenHands agents in disposable Docker sandboxes, locally or in CI, with the same server reachable through a hosted runtime for large evaluations. The right sandbox layer if you are already building on the OpenHands SDK; elsewhere a general container or microVM sandbox is simpler.

  • OpenSandbox

    Apache-2.0 sandbox runtime for agents that starts on Docker, scales on Kubernetes and offers a Firecracker "Fast Sandbox" with pause/resume.

    • Containers or Firecracker
    • Open source
    • Self-hostable
    • Pause/resume

    How it differs: Teams that want an open, multi-language sandbox API they can run from a laptop Docker daemon up to a Kubernetes cluster. The most broadly supported open sandbox API of this batch, with real microVM isolation available once you are on Kubernetes.

Local sandboxes for coding agents

Isolation for agents like Claude Code, Codex or Gemini CLI on your own laptop.

  • Docker Sandboxes

    Docker’s `sbx` CLI for running AI coding agents in microVM sandboxes on your machine, with an experimental Docker-hosted cloud.

    • MicroVM
    • Self-hostable
    • GPU
    • Pause/resume

    How it differs: Running coding agents unsupervised on a laptop with microVM isolation. The easiest way to give local coding agents a real microVM boundary.
