Introduction to Cosmonic
What is Cosmonic Control?
Cosmonic Control is a Kubernetes-native control plane for securely running microservices, agentic workflows, MCP servers, and other sensitive or untrusted code in WebAssembly (Wasm) component sandboxes. Ultra-dense workloads easily deploy on any cloud or edge, including your own on-premises environment, mitigating risks like prompt injection, lateral movement, and remote code execution.
Built on the Incubating CNCF project wasmCloud, Cosmonic Control helps platform engineering teams reduce costs by scaling to zero and maximizing node density, all while providing enterprise-grade security for agents, functions, and other code—and integrating seamlessly with existing cloud-native tooling.
- If you'd like to try it out, get started for free now.
- If you're an operator interested in how Cosmonic Control works, explore the Architecture and Operations documentation.
- If you're a developer building Wasm components, check out the Cosmonic Control Template Catalog and wasmCloud Developer Guide.
What is Cosmonic Desktop?
Cosmonic Desktop is a sandbox for your agent's code: a free, cross-platform desktop app (macOS, Windows, Linux), now in public beta, that runs WebAssembly component workloads entirely on your own machine. No account, no cloud, no Kubernetes required. An integrated MCP server gives coding agents like Claude Code and Codex the skills to compile apps and deploy them into your local sandbox, and the same Workload manifest deploys unchanged to Cosmonic Control: the boundary you trusted in development is the boundary that ships to production. Get started with Cosmonic Desktop.
How does it work?
- Teams compile code to WebAssembly component sandboxes, using open source tooling and streamlined pipelines for builds, attestation, and publication.
- Workloads can be deployed declaratively with any GitOps.
- Sandboxed workloads are deployed to Cosmonic Control hosts with routing via our ingress proxy.
