v0 by Vercel
Overview
v0 is Vercel's AI coding agent. It generates production-ready React code based on Next.js + Tailwind CSS + shadcn/ui from prompts, and covers Git integration, a code editor, database connectivity, and agentic workflows in one platform.
Key Features
Production-Ready React
Generates ready-to-use code based on Next.js + Tailwind CSS + shadcn/ui. Accepts screenshots, mockups, and Figma design imports. Svelte and Vue have only limited support, and stacks such as Angular or Material UI require substantial rewriting of the output.
Agent Model Selection
Four v0 agent models are selectable by task, and billing is token-based, scaling with the complexity of each generation.
| Model | Input (per 1M tokens) | Output (per 1M tokens) | Best for |
|---|---|---|---|
| v0 Mini | $0.20 | $1.20 | Small edits, drafts |
| v0 Pro | $2 | $10 | Everyday development |
| v0 Max | $5 | $25 | Complex multi-file edits |
| v0 Max Fast | $10 | $50 | Fastest, hardest tasks |
Agentic Full-Stack Development
- Git integration — create branches and PRs from chat
- Code editor — edit generated code file-by-file with a diff view
- Database connectivity (Neon, Supabase)
- Sandbox runtime for full-stack apps
- Agentic workflows — coordinated agents split planning, research, code generation, and debugging, picking the best model per step
Figma Import
Import Figma designs to auto-generate matching React code.

- v0 can now run terminal commands — it spins up a browser session to test interactions, reviews git history, writes and runs tests, and uses CLIs to work with Vercel or GitHub, all from the chat (Source: https://x.com/v0/status/2052849095598133593)
- v0 shipped a new API for programmatic access: start a chat from a prompt, repo, or ZIP, render a dev server preview, send follow-up messages, and deploy to Vercel — all from code (Source: https://x.com/v0/status/2084364099367133381)
