Bolt
Full-stack apps built and run in the browser, framework of your choice.
What it is
Bolt runs the project in a browser sandbox, so a prompt produces a running full-stack app with a database, not just a component. That is broader than v0 and less polished per-screen. Use it for prototypes and internal tools you want to see working today; do not expect it to maintain a large existing codebase.

Bolt pricing explained
Free gives 300K tokens a day with no card; Pro at $25 a month removes the daily cap; Teams at $30 per user adds shared capacity and admin controls; Enterprise is a quote. The thing to understand before subscribing is that tokens, not features, are what you run out of — a large project consumes them faster than a small one, and there is no way to buy your way out of the context limit. Check the official pricing page for current limits, since the token allowances have been adjusted more than once.
Free-tier limits are taken from the official pricing page on the update date above. They change often — confirm before you commit to an annual plan.
Bolt key features
Prompt to a running full-stack app
Not a component — an application with routing, a server and a database, running in the browser tab you are looking at.
Framework choice
React, Vue, Svelte, Astro and others. Being framework-agnostic is the clearest difference from the React-only generators.
In-browser Node runtime
The project runs in a WebContainer, so there is no container to wait for and no local setup to break.
Database and auth integrations
Wires up a real backend service rather than mocking one, which is what makes the result a prototype you can show.
One-click deploy
Netlify or Vercel, from the same screen. The gap between "working in the tab" and "working at a URL" is one button.
Live error fixing
Console errors feed back into the model, so a broken build can often be repaired without you diagnosing it first.
Bolt: how it works
WebContainers instead of remote VMs
Node runs inside the browser sandbox, which removes provisioning latency entirely. The trade is that the runtime is not identical to your production container.
Full project generation, not file patches
It scaffolds a project with dependencies and configuration, then edits within it. That is why framework choice is possible and why very large projects start to strain.
Token budget as the real limit
The constraint on a big project is context, not compute: past a few dozen files the model spends its allowance remembering the codebase instead of changing it.
Bolt core strengths
Produces a running app with a backend
The category distinction that matters: v0 hands you components, Bolt hands you something you can click through end to end, including the server and the database behind it.
Framework-agnostic
If your team is on Vue or Svelte, this is the generator that meets you there instead of forcing a rewrite into React first.
Code export means no lock-in
The whole project downloads as a repo. You can walk away with something a developer can maintain.
Error fixing without diagnosis
Feeding console errors back in turns "it broke" into "it is fixed" without you reading a stack trace.
Bolt compared with alternatives
| Tool | Bolt | v0 | Replit |
|---|---|---|---|
| Best for | Full-stack prototypes with a backend, any framework | Front-end prototyping on React and Vercel | Learning and small projects where no local setup is possible |
| Pricing shape | Free / Pro $25 / Teams $30 per user | Free (public projects) / Premium $20 per month | Free / Core $20 per month |
| Output | A complete project including server code and database | React and Tailwind components you can take away | A hosted workspace plus deployment |

Pros and cons
Strengths
- Produces a running app with a backend, not just front-end files
- Framework-agnostic, unlike the React-only generators
- Code export means you can walk away with the repo
Limitations
- Token limits are consumed fast by large projects
- Struggles once a project grows past a few dozen files
- Browser runtime can diverge from your production environment
Bolt use cases
Internal tool in an afternoon
A form, a database and a list view, deployed to a URL — the kind of thing that otherwise waits a quarter for engineering time.
Prototype with real auth
Wire up a login flow so the demo behaves like the product rather than a mockup with a fake avatar in the corner.
Framework-specific scaffold
Start a Svelte or Astro project from a prompt instead of a starter template you then have to gut and rebuild.
Teaching and demos
Because it runs in the browser, there is nothing to install on the audience’s machines — a link is the whole setup.
