v0
Vercel's chat-based AI builder that turns prompts into deployable Next.js, React, Tailwind and shadcn/ui code, from single components to full-stack apps.
Who it's for
Developers who want production-quality React and Tailwind components generated from a prompt and are willing to wire up their own backend logic.
Standout details
- Output is real code built on shadcn/ui and Tailwind, installable straight into an existing project through the shadcn CLI rather than locked inside the tool
- Relaunched from v0.dev to v0.app in August 2025, expanding from single-component generation to full-stack apps with a Next.js sandbox, Supabase integration and one-click Vercel deploy
- Free plan gives $5 of monthly credits capped at 7 messages a day, enough to judge component quality before paying
- Plus is $30 per user a month for $30 of credits plus $2 of daily login credits; Business is $100 per user a month; a legacy $20/mo Premium plan is closed to new signups
- Credits roll over but expire after 65 days, and user reports describe a $30 top-up running out within two days on a heavy week
What it is
v0 is Vercel’s chat-based app builder. You describe a component, page, or app, and it generates working code on Next.js, React, Tailwind CSS and shadcn/ui, previewable in the chat and ready to copy or install into an existing project. It launched as v0.dev, a UI and component generator built for developers already working in that stack. Vercel relaunched it as v0.app in August 2025 and expanded the scope through a full rebrand completed by January 2026: specialized agents for web search, file reading, design inspiration, task management and quality checks, plus a Next.js sandbox, Supabase integration and one-click Vercel deployment, so a prompt can now produce a working full-stack app rather than just a component.
Who should use it
Developers already working in Next.js, Tailwind and shadcn who want a fast first draft of a UI: a dashboard widget, a form, a landing page, a layout. It fits people comfortable taking generated code and wiring it into a real project themselves, less so anyone hoping to describe a full app once and get a finished backend out the other end.
What stands out
The code is the product, not a preview of it. What v0 generates is real shadcn/ui components and Tailwind classes, installable through the shadcn CLI, so nothing is trapped behind a proprietary export step.
Pricing runs on credits rather than a flat seat price. Free gives $5 of monthly credits with a 7-message daily cap, enough to see whether the output fits your stack before paying. Plus is $30 a user a month for $30 of credits plus $2 of daily login credits, and Business is $100 a user a month. A legacy Premium plan at $20 a month still exists for people who had it before the restructure but is closed to new signups. Credits roll over month to month but expire after 65 days, and multiple users report a $30 top-up running out in a couple of days once a session moves past simple component generation into heavier, multi-step work.
The August 2025 relaunch changed what v0 is for. It started as a tool for one component at a time and now ships agents that plan a build, search the web, and check their own output before handing back a full-stack app with a database attached. That is a lot more than the original v0.dev promised, and reviewers say the reliability of the added agentic layer has not fully caught up to the UI generation it was already good at.
The verdict
For UI work in a stack v0 already knows, it is quick and the output holds up: clean components, sensible Tailwind, nothing to detangle before you can use it.
Push it toward full-stack app building and the cracks reviewers describe start to show: multi-step flows, state management and backend wiring are where it needs the most hand-holding, and every correction spends more of a credit balance that was never generous to begin with. Treat v0 as a frontend generator that happens to also attempt full-stack apps, not the other way around, and you will get more out of it than the marketing promises.
Honest verdict
v0 earns its keep as a fast way to get a clean, on-brand component or page, and the output is real shadcn and Tailwind code you can drop into a project rather than something locked behind the tool. The full-stack ambitions since the v0.app relaunch are the part to watch: reviewers describe it struggling with multi-step flows, state management and backend wiring, and credits disappear quickly once you push past UI generation into real app logic. Use it as a frontend scaffolding tool, not a replacement for writing your own backend, and budget for top-ups if you use it daily. Skip it if you need something to handle auth and data modeling for you end to end.
