v0 is Vercel's tool for generating web interfaces from a description. Type what you want, a pricing page, a dashboard with a sidebar and a data table, an intake form with validation, and it writes React code using Tailwind CSS and the shadcn/ui component library, then renders it live so you can click around. You refine by chatting, point at an element and ask for a change, or edit the code directly.
It started as a component generator for developers and has grown into something closer to a full app builder: it can wire up a database, add authentication, call an API, and deploy to Vercel in a click, with the code synced to GitHub. That growth is why non-developers now use it for internal tools and prototypes, and why an honest review has to separate the UI generation, which is excellent, from the full-stack generation, which is uneven.
The output looks good by default because shadcn/ui looks good by default. That is a feature when you need a clean internal tool by Friday and a limitation when you need something that does not look like every other v0 project. Credits meter every generation, and iterating on a stubborn bug burns them fast.
Best for
- Software developers who want a first draft of a page or component in their stack in minutes, then take the code into their own repo
- Product managers who need a realistic clickable prototype to test an idea before design and engineering commit
- UX designers translating a mockup into a coded prototype to check interaction and responsiveness
- Small-business owners building a simple internal tool, calculator, or landing page without hiring
- Engineers on other teams who need a quick front end for a script or an API they already have
Not ideal for
- Teams not on React; the output is React, Next.js, and Tailwind, and porting it elsewhere loses most of the value
- Applications with complex business logic, payments, or sensitive data, where generated backend code needs an experienced engineer's review
- Pixel-exact brand implementations; you will spend more time fighting defaults than you save
Key features
Pricing
A free tier with a small monthly credit allowance for generations; a paid individual Premium plan with a larger allowance and more capable models; Team plans with shared projects and billing; and Enterprise agreements with security and higher limits. Usage is measured in credits that vary by model and message size, and the plan lineup has changed several times. Check the vendor's current pricing page.
Credits go to iteration, not first drafts. Write a detailed first prompt with the exact fields, states, and behaviors you want, and use design mode for cosmetic changes.
Pricing changes often. Confirm current plans on the vendor's site before you buy.
Pros and cons
Pros
- Best in its class at turning a description into a clean, responsive UI in a stack developers already use
- Live preview and element-level edits make iteration feel like working with a fast junior developer
- Deploy and GitHub sync remove the gap between a prototype and something a team can pick up
- The free tier is enough to build and share a real prototype
Cons
- Everything looks like shadcn/ui until you invest effort, and clients notice
- Credits drain quickly when you are debugging by chat, and it can loop on the same bug
- Backend and data logic are the weakest part; generated auth, validation, and error handling need review
- Tied to the Vercel and Next.js ecosystem, which is great if that is your stack and friction if it is not
- Non-developers hit a wall when something breaks that the chat cannot fix
How people use v0 at work
Product managers: test a feature idea with a clickable prototype
Write the flow as screens with real field names and the empty, loading, and error states, and generate. Share the preview link with five users and watch them use it. Hand the link and your notes to design and engineering as the brief.
Software developers: scaffold the boring pages
Describe the settings page, the table with filters and pagination, or the onboarding form, generate, and pull the code into your repo. Replace the placeholder data layer with yours and delete anything you would not have written.
Small-business owners: build an internal calculator or intake tool
Describe the inputs, the formula or rules, and what the result screen should say, then deploy it on a Vercel URL for your team. Test the edge cases yourself with real numbers before anyone relies on it.
UX designers: check a design in a real browser
Export a frame from Figma as an image, ask for a faithful build, and open it on your phone. Interaction and responsiveness problems that are invisible in a mockup show up immediately.
Getting started
- Sign in at v0.app and describe a single screen you actually need, including every field, button, and state. Vague prompts produce vague pages.
- Click around the preview. Select an element and ask for one specific change to learn how targeted edits work, then switch to design mode for colors and spacing.
- Open the code panel and read the main component. Even if you do not code, notice the placeholder data so you know what is fake.
- Deploy the preview, open it on your phone, and share the link with one colleague for feedback. If it is going anywhere real, push to GitHub and have a developer review the data and auth code.
