What OpenPage is

OpenPage is an open-source website builder combining a visual drag-and-drop editor, AI site generation, and a JSON-first architecture. The editor provides real-time preview, block reordering, and inline editing. A text prompt can generate a complete website configuration through Google’s Gemini model, which requires a Gemini API key. OpenPage includes 19 block types, 42 layout variants, and 10 built-in theme presets. It exports standalone HTML files that can be hosted with Vercel, Netlify, GitHub Pages, or S3. The POST /api/generate endpoint accepts a prompt and returns a structured SiteConfig JSON object. The editor can run locally, while the AI endpoint can be deployed as a Vercel serverless function or adapted to another backend. Listed uses include startup landing pages, AI agent workflows, client sites, portfolios, SaaS marketing pages, white-label builders, and rapid prototyping. It is built with React 19, TypeScript, Tailwind CSS, Zustand, and Vite, and is MIT licensed with no usage limits, paid tiers, or telemetry.
