metaharness vs sourcey
metaharness: MetaHarness is a CLI and browser Studio that mints custom AI agent harnesses from any GitHub repository, creating a repo-aware CLI, coding agent, and local MCP server tailored to the project. It acts as a factory for agent frameworks, allowing users to ship their own branded, npm-publishable AI agents with custom memory, governance, and model routing.; sourcey: Sourcey is a static documentation generator that consolidates various source formats like OpenAPI, Doxygen, and Markdown into a single, self-owned HTML site. It renders all content at build time, ensuring no runtime dependencies or API calls for your documentation.
