Cosmonic Information

Cosmonic sandboxes the code your agents write. Your coding agent writes and runs code in your name: MCP servers, scripts, and tools, all with access to your files, network, and keys. Cosmonic runs that code in a deny-by-default WebAssembly sandbox instead, where every app starts with no access to anything until you grant it. It isn't that the code tries something and gets blocked. It has no way to try. Cosmonic Desktop (public beta, free): the AI sandbox on your own machine. Works with Claude Code, Codex, Gemini CLI, Cursor, and any agent that speaks MCP. Inspect exactly what each app can reach before it runs. macOS, Windows, and Linux. Cosmonic Control: the same sandbox and the same manifests at cluster scale. Thousands of workloads per node, scale to zero when idle, per-workload capability grants and egress policy. Runs on EKS, AKS, GKE, OpenShift, VMware, on-prem, and fully air-gapped. Free to start. Start on your laptop. Ship on your cluster. Same model, same manifest, no rewrite between the two. Built on CNCF wasmCloud, the open source runtime we created, so nothing you build is locked in.
