v0 (by Vercel) is an AI frontend generator: plain-English prompts become React + Tailwind components, deployable instantly to Vercel, with a full-stack sandbox, Git integration, database connectivity and a VS Code-style editor.
Free: $5 in monthly credits (token-based since Feb 2026, cost scales with prompt/model complexity). Plus $30/month, Business $100/month, Enterprise custom, the legacy Ultra plan was retired in 2026.
Developers and designers already in the Vercel/Next.js ecosystem who want to go from a prompt to a deployed, production-ready frontend in one workflow.
Token-based pricing (since Feb 2026) means complex prompts and heavier models burn credits faster than simple ones: scope prompts tightly on the free tier rather than requesting large multi-component generations at once.
