Coasts is an open-source development runtime and orchestration harness built in Rust by the coast-guard organization. It provides containerized and process-level isolation infrastructure designed to run, manage, and coordinate automated developer workflows, daemon services, and AI coding agent tasks safely within defined project boundaries. The system operates via a multi-component Rust architecture comprising a central command-line interface (`coast-cli`), a background execution daemon (`coast-daemon`), core runtime libraries (`coast-core`), and container runtime integrations (`coast-docker`). Day-to-day interactions occur through standard terminal commands where developers initialize isolated project environments, supervise long-running agent or background processes, and orchestrate network communication using host-level socket supervisors like socat. Unlike standard agent harnesses that execute uncontained subcommands directly on the developer's host machine, Coasts emphasizes containerized sandboxing and lifecycle supervision. Its dedicated background daemon monitors service lifecycles, handles autostart configurations, and coordinates local system boundaries so agentic code generation and testing routines execute deterministically without dirtying host state. Coasts is open source and hosted on GitHub under public repository licensing. Because it is compiled as native Rust binaries, it is lightweight, cross-platform, and targets developers requiring deterministic local execution sandboxes for autonomous workflows.
