Cosmonic
Cosmonic sandboxes the code your agents write. Each MCP server or service runs with no access to your files, network, or keys until you grant it.
Présentation
Cosmonic Desktop ships an MCP server, so any coding agent that speaks MCP can build and deploy into the sandbox, including Claude Code, Codex, Gemini, opencode, and local models. Nothing here is tied to one vendor.
A container starts with broad access to the machine that launched it. A Cosmonic sandbox starts with none: an app can reach only what you granted. Sandboxes are also much smaller and quicker to start, so you can afford to run thousands of them, and they run beside the containers you already have rather than replacing them. The AI sandbox guide compares containers, microVMs, and WebAssembly in depth.
Your coding agent writes and runs code in your name: MCP servers, scripts, and tools, all with access to your files, network, and keys.
Most software runs with too much access to your files, keys, network, and more.
Anything you want contained: ready-made MCP servers and apps from its built-in catalog, the code your agent writes, functions, workflows, and whole applications. Each one runs in a sandbox that starts with no access to your files, network, or keys until you grant it.
