Code Sandboxes
Isolated cloud machines for agents to run code, browse, and use tools.
Secure sandboxes for running AI-generated code. Its public GitHub repo is archived: core development moved to a private codebase in June 2026.
Serverless cloud for running, training, and serving AI workloads, including sandboxes.
Isolated Linux microVMs on Vercel for untrusted or agent-generated code.
Code sandboxes (Devboxes) for AI coding agents, plus evaluations.
Run untrusted or generated code in Linux VMs or isolated Workers on Cloudflare.
Cloud sandboxes for running AI agents, positioned as lower-cost agent infrastructure.
All-in-one agent sandbox with browser, shell, file access, VSCode Server, and MCP in one container.
Isolated microVM sandboxes where AI agents and developers run untrusted code, via REST API, TypeScript and Python SDKs, and an MCP server (beta).
