Open-source sandboxed.sh is a self-hosted mission-execution backend for autonomous coding agents: each unit of work runs in a throwaway containerized Linux workspace with streamed structured results, so agents do not own the whole host. Runtimes include Claude Code, OpenCode, Codex, Gemini, and Grok, with Docker and native Ubuntu install paths.
