v0
VercelAI-powered generative UI and full-stack development agent from Vercel that builds web applications from natural language prompts. Can autonomously generate React/Next.js components, assemble full pages, manage state, connect to APIs, and iterate based on visual feedback. Differentiates through frontend-first design quality and tight Next.js/Vercel deployment integration. Evolved from a UI generation tool into a full autonomous development agent in 2025.
v0 by Vercel (v0.app), agentic full-stack web app builder ('agentic by default', autonomous plan/create-tasks/connect-DB as it builds); web + iOS, subscription (v0 Pro). Verified live June 2026 at v0.app. (Note: prior record's 'powered by Claude Opus 4.8' could NOT be confirmed on the product page. No model named publicly; claim softened.)
