OpenSandbox

Secure, fast sandbox runtime for AI agents to run code.

microsandbox

Local-first microVM runtime for running untrusted agent code safely.

Agent Sandbox (Kubernetes)

A Kubernetes project that adds a Sandbox resource for running isolated, stateful agent workloads such as code execution and browsers, with warm pools and fast startup on your own cluster.

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.

Tensorlake

Serverless runtime that gives agents MicroVM sandboxes and durable orchestration for long-running background jobs.

Perplexity SPACE

Perplexity's open-source sandbox platform that runs each agent task in its own Firecracker microVM, with credentials and network access controlled from outside.
