v0 has actually changed my prototyping workflow

I have used every AI UI generator to ship in 2024 and 2025. v0 is the only one whose output I keep without rewriting.

What it does

Describe a UI in plain English. v0 emits a working React component using Tailwind and shadcn/ui. The output is production quality, not a sketch.

What changed in 2025 was the move from "v0 generates a single file" to "v0 generates a coherent multi-file component tree with shared types". That made it useful for real product work, not just landing pages.

What I use it for

- Internal admin UIs where I do not want to spend a week styling forms - Marketing pages where I want a polished hero in 30 minutes - One-off dashboards that will live for three months and then be deleted - Component libraries I am scaffolding from a design system

What I do not use it for

- Anything performance-sensitive (I check the output, but I trust my own architecture more) - Highly stateful UIs (the prompt-to-component model breaks down on complex state) - Brand-critical surfaces (I want a designer in the loop)

Free tier

Good enough to evaluate. [Sign up via this link](https://v0.app/ref/HTXSFQ) to start with credits.

What I changed in my workflow

I used to mock UIs in Figma, get them reviewed, then build them. Now I prompt v0, get a working version, iterate in code with the team, and Figma becomes a polish layer rather than a starting point.

The shift is significant. Not because Figma is worse, but because working code is a better object to iterate on than a static mock.

What v0 is not

It is not a replacement for designers. It is not a replacement for engineers. It is a leverage tool for both. Use it that way.
