OpenPage: Open-Source AI Website Builder

**OpenPage is an open-source website builder that uses JSON as the single source of truth.** It combines a Framer-like visual drag-and-drop editor with AI-powered site generation, producing websites that are fully described by a structured, typed JSON config. Unlike code generators (Lovable, v0, Bolt) that produce fragile output, or visual editors (Framer, Webflow) that lock you into proprietary formats, OpenPage gives both humans and AI agents a shared, predictable interface to build and edit websites.
