Bolt vs v0: Two Full-Stack Builders, Two Different Homes
September 28, 2026
If you're weighing Bolt vs v0 and every article tells you "v0 makes UI components, Bolt makes full apps," close the tab. That split is out of date.
As of September 2026, both build full-stack apps with a database, authentication, hosting and custom domains. They have converged on what they build. They differ on where it lives:
- Bolt runs in your browser and puts the backend and hosting inside Bolt itself. A database appears when your app needs one, and publishing goes to Bolt's own hosting by default.
- v0 runs in a cloud VM and puts everything on Vercel. You pick a database provider through the Vercel Marketplace, work through GitHub branches and pull requests, and deploy to a Vercel project.
So the useful question isn't "which one builds a real app." Both do. It's whose platform you want to be standing on in a year, and what walking away would cost.
Quick comparison
| Bolt | v0 | |
|---|---|---|
| Builds full-stack apps | Yes | Yes |
| Where the dev environment runs | In your browser, via WebContainers | In a cloud VM, via Vercel Sandbox |
| Default database | Bolt Database, created automatically | None until you add one |
| Other database options | Supabase (paid plans) | Neon, Supabase, Upstash, Vercel Blob via Vercel Marketplace |
| Default hosting | Bolt hosting on a .bolt.host address | Vercel, preview and production deployments |
| Other hosting | Netlify if chosen before the first publish, or download and host anywhere | Export the code and deploy elsewhere |
| Git workflow | Auto-commits to a synced GitHub repo | Working branches, pull requests, CI status |
| Framework | JavaScript web frameworks; Expo for mobile | Next.js by default; Vite and Node detected |
| Billing unit | AI tokens | Tokens |
| Platform gravity | Bolt | Vercel |
They have converged, so stop comparing scope
Here is what each vendor's own docs say today.
Bolt now ships Bolt Cloud. Its Bolt Cloud overview lists hosting, domains, databases, built-in authentication, file storage, server functions, analytics and Stripe payments. Per the database docs, Bolt creates a database automatically when your project needs one. You don't set anything up.
v0 stopped being a component generator a while ago. Its full-stack guide covers backend endpoints using Next.js App Router conventions, database connections and user authentication. Its deployments docs cover preview deployments, production deployments and custom domains.
Put those side by side and the scope gap is gone. A non-technical founder can get a working app with sign-up, stored data and a live URL out of either one.
What hasn't converged is the plumbing underneath. That's where the rest of this post lives.
Where Bolt is stronger
The backend is already there. On Bolt, the database is a default, not a decision. It comes with auth, user management, secrets and logs in the same project panel. If you've never chosen a database provider and don't want to start now, that removes the step where most first projects stall.
Everything lives in one dashboard. Hosting, domains, database and analytics all sit inside Bolt. You can even buy a domain from inside the project. Fewer accounts, fewer places for a setting to hide.
Mobile apps are a documented path. Bolt's Expo integration builds one codebase for iPhone and Android, with publishing to TestFlight, the App Store and Google Play. v0's docs center on web apps.
Nothing to install, and the code is right there. Bolt runs on WebContainers, so a Node environment runs inside your browser tab. You can edit files directly in code view and download the whole project as a zip to run in your own editor.
| You want | Why Bolt fits |
|---|---|
| A database without choosing one | Bolt Database is created for you |
| One place for hosting, domain and data | Bolt Cloud bundles them |
| A mobile app in the stores | Expo integration |
| To start building with zero accounts | No provider sign-ups required |
Where v0 is stronger
It fits a real engineering workflow. Per v0's GitHub docs, you can import an existing repository, and every change goes to a working branch. v0 opens or reuses a pull request and shows CI checks. It never pushes directly to main. If a developer reviews your code, or will one day, this is the workflow they already use.
Previews behave like production. v0 runs your app in a sandbox, a lightweight VM with a full Node.js environment, a terminal, and your project's environment variables. The docs say this replaced the older browser-based preview, which couldn't run server code, API routes or real database connections.
You choose the database, and it sits in its own account. v0's databases guide lists Neon, Supabase, Upstash and Vercel Blob. Adding one provisions an account on that service and wires the environment variables into your project. For SQL databases, v0 can also create and change tables. Your data lives with a provider you picked, not inside the builder.
The code is mainstream. Next.js, React, TypeScript, Tailwind CSS and shadcn/ui, per v0's FAQ. Any Next.js developer can pick it up.
| You want | Why v0 fits |
|---|---|
| Pull requests and code review | Branch-and-PR workflow with CI status |
| To work on an existing codebase | Import from GitHub, a Vercel project or a zip |
| A specific database provider | Vercel Marketplace integrations |
| Previews that match production | Vercel Sandbox VM |
What leaving costs
This is the section most comparisons skip. It's also the one you'll care about in a year.
Leaving Bolt. Your code is easy: download the zip, or keep the synced GitHub repo, which Bolt commits to automatically. The data is the harder part. Bolt Database lives inside Bolt. Per its Supabase docs, the way to move it is to "claim" it into your own Supabase account. That's a paid-plan feature, and connecting a fresh Supabase database instead replaces the connection and may cause data loss. The same page says there is no supported flow back from Supabase to Bolt Database. Hosting is only easy to swap early. Per the Netlify docs, new projects publish to Bolt hosting by default, and you can pick Netlify instead, but only before the first publish to Bolt hosting. After that, "There is no going back": Bolt says to make a new, unpublished copy of the project, or you download the code and redeploy it elsewhere.
Leaving v0. The code is ordinary Next.js, and v0's FAQ says you can export it and deploy elsewhere. The database is already in your own account with Neon, Supabase or whichever provider you picked, so there's no claiming step. What you give up is the Vercel layer. The same FAQ says the full experience (environment variables, deployments, previews) needs your repo connected to a Vercel project. Leave Vercel and you rebuild that pipeline yourself.
| Bolt | v0 | |
|---|---|---|
| Getting the code out | Zip download or GitHub sync | GitHub repo or export |
| Getting the data out | Claim into Supabase (paid plans) | Already in your provider account |
| Replacing hosting | Netlify before first publish; after that, redeploy the code elsewhere | Anywhere that runs Next.js |
| What you lose | Bolt's bundled cloud | Vercel's previews and deploy pipeline |
The honest summary: Bolt couples you more tightly at the data layer, and at the hosting layer once you've published to Bolt hosting. v0 is the reverse at the data layer. The data stays with an independent provider, and the workflow is shaped around Vercel.
Neither coupling is bad. It's what buys the speed. Just pick it knowingly, before you have users to migrate.
Choosing between Bolt and v0
- Non-technical, want a working app with a database this week? → Bolt. The database and hosting are defaults, not decisions.
- Want iPhone and Android apps, not just a website? → Bolt, through Expo.
- Have a developer, or an existing GitHub repo? → v0. Branches, pull requests and CI are the workflow you'll want anyway.
- Already on Vercel and Next.js? → v0. It's built for that stack.
- Worried most about who holds your data? → v0, where the database lives in a provider account you own from day one. Or start Bolt with Supabase if you're on a paid plan. Bolt's docs say choosing it from the outset avoids the extra steps of switching later.
- A throwaway prototype? → Either. Optimize for speed and ignore the exit cost.
On price, both bill in tokens and both reprice regularly. Check Bolt's pricing and v0's pricing directly. For how Lovable fits against each, see Lovable vs Bolt and v0 vs Lovable.
When you don't need a new app
Bolt and v0 are both built to generate an app from a prompt. That's the right tool when what you want doesn't exist yet.
Often it does. Plenty of what people want from AI is a setup someone already got working: an agent, a workflow, a small app shared on X that does exactly the job. Rebuilding it from a prompt means starting over when a working version is already out there.
Taku is shaped for that case. It's an AI-native desktop workspace where you mirror an AI app, skill or workflow that already works, run it, remix it, and keep it. It isn't an app builder, and it doesn't compete with Bolt or v0. When you need to build something new, they are the stronger tools. Taku is in Beta, and the Mac app is available now. The free app library shows what mirroring looks like.
FAQ
Is v0 only for UI components?
No. As of September 2026, v0 builds full-stack apps with backend endpoints, databases connected through the Vercel Marketplace, authentication, and production deployments on Vercel. "UI components only" describes an early version of the product.
Does Bolt include a database?
Yes. Bolt creates a Bolt Database automatically when your project needs one, with auth, secrets and logs built in. On paid plans you can use Supabase instead.
Which is easier to leave, Bolt or v0?
It depends on the layer. v0 is easier at the data layer, because your database already sits in your own provider account. Bolt lets you pick Netlify hosting, but only before the first publish to Bolt hosting; after that you redeploy the downloaded code elsewhere. Moving Bolt Database means claiming it into Supabase.
Can I deploy a v0 app somewhere other than Vercel?
Yes. The code is standard Next.js, and v0's FAQ says you can export it and deploy elsewhere. You lose v0's built-in previews, environment variables and deploy pipeline, which all depend on a connected Vercel project.
Which is better for a non-technical founder?
Usually Bolt. Both build a real app, but Bolt leaves you fewer decisions to make: the database and hosting just appear. v0's branch-and-pull-request workflow is great for developers and more machinery than most beginners want. For the wider field, see AI app builders compared.
Can I use both?
Yes, and some people do. Prototype quickly in Bolt, then move to a GitHub repo with v0 once a developer is reviewing changes. Plan the database move before you have real user data in it.
