Crewplane

About

Crewplane is an open-source workflow runner that executes coding-agent CLIs such as Claude Code, Codex, Gemini and GitHub Copilot CLI according to stages defined in Markdown. Workflows can run steps in parallel or in sequence, be composed into larger pipelines and be resumed after interruption. Inputs, intermediate outputs, logs and manifests are kept on disk so a run can be traced afterward, and a built-in mock CLI lets you test workflow syntax without model calls.
