Which to pick
Pick v0 by Vercel unless Speed is what decides it for you, which is exactly where Bolt is the better answer.
Bolt
Bolt builds and runs the whole project in the browser, which makes the loop between asking and seeing unusually short. It is happiest with self-contained projects where you want to poke at the files yourself, and it is candid about handing you the terminal when you need it.
Where it shines
- Install, run and edit happen in the tab, so there is no local setup at all
- Full file access the moment you want to stop prompting and start typing
- Fast to prototype something rough and iterate on it in one sitting
v0 by Vercel
v0 generates React and Next.js interfaces from a prompt or a screenshot, and hands you the source. It assumes a developer is in the loop, which is exactly why the output is easy to take somewhere else. As a way to skip the first eighty percent of a page, it is very hard to beat.
Where it shines
- The code is yours, readable, and ships straight into an existing codebase
- Screenshot-to-interface is genuinely accurate for layout and spacing
- Sits naturally next to the rest of the Vercel deployment workflow
