This MIT self-hosted CMS runs visual editor, content engine and publisher in a single Bun server, and its agent builds pages "as real, editable nodes, not a screenshot or a wall of code." The notable design decision is role-specific tool scoping — 35 tools exposed for site building versus 15 for content editing — with provider-agnostic drivers for Claude, OpenAI, OpenRouter and Ollama on a bring-your-own-key basis. Published pages are static HTML and CSS with no framework boot, hydration step or database round-trip; the stack is React 19, Vite and Zustand on SQLite or Postgres with a QuickJS-WASM plugin sandbox. Deliberately pre-1.0 at 6,247 stars.
