What VertexOS is

VertexOS is a free, open-source, local-first workspace for generating, editing, and exporting websites with AI. It turns a business discovery brief into a design brief and then an industry-aware site that can be previewed and refined section by section. The project lists 15 design systems, including Liquid Glass, Apple Vision Pro, Linear, Raycast, Vercel, and Framer. Supported AI options include NVIDIA NIM, OpenRouter, DeepInfra, Google Gemini, Ollama, and custom OpenAI-compatible endpoints. Without an API key, its deterministic Design DNA engine can generate a site offline, while Ollama supports local models. VertexOS exports a runnable Next.js and Tailwind project for deployment elsewhere; hosting is not included. Briefs, keys, and projects remain in the browser, with drafts and projects in local storage and images in IndexedDB. No account is required. Installation needs Node.js 18.18 or later and npm, with Node 20 or later recommended. The project is beta and MIT-licensed.
