From the README
<div align="center"> **kern:** rootless container runtime and sandbox with no daemon. Runs agent tool calls and LLM-generated code in kernel-enforced containers. **A real, kernel-enforced container in a few milliseconds, out of one static binary with no daemon.** **MCP support** for Claude Code, Cursor, Claude Desktop and LM Studio, through Kern Sandbox. <sub>**0 RAM at rest** · no daemon, no socket, nothing to start · one static binary, `libc` its only Rust dependency</sub> </div> ```sh # Linux. Windows and macOS below. curl -fsSL https://raw.githubusercontent.com/getkern/kern/main/install.sh | sh ``` --- ## What kern is A rootless container runtime in one static binary, with no daemon. The same binary is the sandbox an agent's code runs in, called from Python, Node or any MCP client. kern calls a container a **box**. - **Real OCI images**: `pull`, `build`, `commit`, `push`, `save`/`load`. A box starts in single-digit milliseconds. - **A sandbox for code your model wrote.*Read full README on GitHub →
