v0 is a capable tool for generating React and Next.js UI components and prototypes, backed by Vercel's deployment infrastructure, but it is not a full-stack builder out of the box, and its 2025 shift to token-based pricing has made costs harder to predict.
v0 is Vercel's AI tool for turning text prompts, screenshots, or Figma files into working React and Next.js code. It started in October 2023 as a narrower UI-component generator and has since expanded into a broader app-building tool, adding a sandbox runtime, database integrations, and a Git-style panel in a February 2026 relaunch. This review looks at what it generates, how its pricing works, how developers and reviewers have responded, and where its limits are.
Type a prompt describing a UI component or a whole app, or attach an image or a Figma link.
v0 returns React and Next.js code built with shadcn/ui components and Tailwind CSS, which you can preview in the browser.
Use the visual editing mode to adjust colors, spacing, typography, and layout by hand, or keep prompting to change the logic.
Add a one-click integration such as Supabase, Neon, Upstash, Snowflake, or AWS to bring in a database; Supabase specifically adds authentication.
Connect a GitHub repo so v0 auto-commits to a dedicated branch and opens pull requests, then deploy to Vercel in one click.

Synthesized from 7 external reviews. Independent signal (Trustpilot / Reddit / verified aggregators) weighted higher than commission-carrying review sites.
There is a free plan with $5 of included monthly credits and a 7 message per day limit, plus deployment to Vercel and GitHub sync. Paid plans start at $30 per user per month for Team and $100 per user per month for Business, billed on top of token-based credit usage.
It generates React and Next.js code, from single components like a nav bar or pricing card to multi-page applications with routing and shared layouts, using shadcn/ui components styled with Tailwind CSS.
Not by default. Independent reviews describe the base product as frontend-only, with no built-in identity provider, session management, or data persistence. You add backend functionality through one-click integrations such as Supabase, which includes authentication, or Neon and Upstash for a database.
Since May 2025, v0 has billed on input and output tokens converted to credits rather than a fixed number of messages. Vercel does not publish a fixed token-to-credit conversion rate. This shift produced a sustained series of complaints on Vercel's own community forum about unpredictable costs, including reports of $10 to $30 in daily top-ups beyond a plan's included credits.
Vercel, the company behind v0, holds a SOC 2 Type II attestation covering security, confidentiality, and availability, and v0 is explicitly included in that scope. Vercel is also ISO 27001:2022 certified at the platform level, and offers HIPAA business associate agreements and PCI DSS attestations depending on plan. On paid Pro plans your content is opted out of model training by default; Enterprise plans exclude data from model training entirely. A specific data retention period for v0 prompts is not published.
In July 2025, Okta's threat intelligence team reported that outside attackers used v0 to quickly generate convincing phishing login pages hosted on Vercel's own domain. This was misuse of the tool by third parties, not a breach of Vercel's systems; Vercel blocked the identified phishing sites after the report.
v0 is a focused tool for generating React and Next.js UI backed by Vercel's deployment infrastructure, and it works well for developers already inside that ecosystem. It is not a general-purpose full-stack builder, its token-based pricing has been a recurring source of complaints since mid-2025, and buyers evaluating it should budget for variable, usage-based costs rather than a flat monthly fee.
