CubeSandbox
Lightweight, concurrent sandbox for running AI agent code securely.
E2B
Secure cloud sandboxes for running agent-generated code.
microsandbox
Local-first microVM runtime for running untrusted agent code safely.
forkd
MicroVM sandbox runtime for AI agent fan-out that forks KVM-isolated child VMs from a warm snapshot in milliseconds.
Cloudflare Sandbox SDK
SDK for running isolated code sandboxes on Cloudflare's network, so agents can execute commands and files safely from a Worker.
Sandbox0
Sandbox0 is a managed sandbox runtime that gives each AI agent an isolated cloud computer where it can run code, install software, manage files and control network access. The whole writable root filesystem persists across incremental checkpoints and grows automatically as it fills, so an agent can pause compute between tasks and resume the same sandbox later with its tools, dependencies and files intact. It adds snapshots and restore, SSH, egress proxy and credential injection, private previews, Docker in the sandbox, webhooks, warm pools and custom templates, with integrations for LangChain Deep Agents, OpenAI Agents, Vercel and GitHub CI. Sandboxes run under gVisor isolation with Nomad scheduling.
