How to Migrate From v0 to Bolt.new
v0 is a great tool for building UI components quickly. You describe a component, it generates React code, you copy it into your project. The friction shows up the moment your project needs a backend: a database, an API route, auth. v0 stops at the frontend boundary. Bolt.new doesn't have that boundary.
Developers making this switch are usually at the point where they've scaffolded a solid UI with v0 and now need the whole application to work. Bolt.new lets you describe a full-stack app, scaffold the backend and frontend together in a live environment, and deploy it without leaving the browser. The mental model is different: you're building an application, not generating components to paste elsewhere.
What's actually different
v0 and Bolt.new have different target users and different scopes, even though the surface appearance (describe a UI, see it rendered) looks similar.
| Feature | v0 | Bolt.new |
|---|---|---|
| Output type | React components | Full-stack applications |
| Backend scaffolding | No | Yes (Node, Express, API routes) |
| Database setup | No | Yes (SQLite, Supabase, etc.) |
| Live in-browser environment | Preview only | Full dev environment (WebContainers) |
| Deploy | No (copy code to your project) | Yes (Netlify, Vercel integration) |
| File system access | No | Yes (full project structure) |
| Package installation | No | Yes (npm in-browser) |
| Auth scaffolding | No | Yes |
| Component library | Tailwind + shadcn/ui | Flexible |
| Pricing | Free (limited) / $20 Pro | Free (limited) / $20 Pro |
The core architectural difference is WebContainers: Bolt.new runs a Node.js environment inside your browser using StackBlitz's WebContainers technology. When you ask Bolt.new to add an API route, it actually creates the file, runs it, and lets you test it live. When you asked v0 for similar functionality, it produced frontend-only code and left the server side as your problem.
Mapping your existing workflow
Component generation. v0's core workflow, "describe a component, get React code," works in Bolt.new too. The difference is Bolt.new keeps the component inside a project with full context. You can say "add a data table component that fetches from the /api/users endpoint I already set up" and Bolt knows about that endpoint.
Shadcn/ui and Tailwind. v0 generates output based on shadcn/ui and Tailwind CSS by default. Bolt.new supports both but isn't locked to them. When you scaffold a new Bolt project, you can choose your stack. For parity with v0's output, start a Bolt project with a "React + Tailwind + shadcn/ui" template.
The copy-paste workflow. With v0, your workflow was: generate component, copy code, paste into your local project. With Bolt.new, everything stays in the Bolt environment. You can export the full project as a zip or connect it to a GitHub repo for a more traditional local development experience.
Iterative refinement. Both tools support follow-up prompts to refine generated code. The difference in Bolt.new is that refinement has full application context. "Make the button disabled while the form is submitting" works in Bolt because it can see the form state, the submit handler, and the button all in one view.
The actual migration steps
1. Export your v0 components. In v0, open each component you want to bring forward and copy the generated code. For complex projects with many components, export them systematically: list each component, copy its code, save it locally in /components/.
2. Start a new Bolt.new project. Go to bolt.new and start a new project. Choose a template that matches your v0 stack (React + Tailwind, or Next.js if your v0 components were Next-flavored).
3. Import your components. In Bolt.new's file editor, create the component files and paste in your v0 code. Alternatively, describe the component to Bolt.new from scratch: "Create a [component name] component using shadcn/ui with these props: [list them]." Recreating from description often produces better-integrated output than pasting v0 code.
4. Add the backend. This is where Bolt.new earns the switch. In the Bolt chat, describe what your backend needs: "Add an API route at /api/users that returns a list of users from a SQLite database. Include schema creation." Bolt scaffolds the route, installs the necessary packages (better-sqlite3 or similar), and wires everything together.
5. Test in the live environment. Bolt.new's preview pane shows your app running in real time. Test the frontend-to-backend connection directly in the browser. No local setup needed.
6. Connect to GitHub. Bolt.new lets you push the project to a GitHub repository from the interface. Do this early to establish version control outside the Bolt environment.
7. Deploy. Bolt.new integrates with Netlify and Vercel. From the interface, connect your deployment target and deploy with one click. v0 had no equivalent; you would have deployed manually after copying code to a local project.
First-day checklist:
- Existing v0 components exported or listed for recreation
- New Bolt.new project started with matching stack
- At least one backend route scaffolded and tested
- Project connected to GitHub
- Deploy target configured
Gotchas you'll hit
The in-browser environment has limits. Bolt.new's WebContainers environment can't run everything. Native Node.js modules that require compilation sometimes fail. If your backend needs a specific database driver or native binary, you may hit a wall.
Projects can drift from local development. If you do significant work in Bolt.new and then export to work locally, keeping the two in sync requires discipline. Commit to GitHub frequently and pull locally often if you're doing hybrid work.
Context window for large projects. As your Bolt.new project grows, the AI's context becomes less reliable for the full application. Targeted, specific prompts work better than "fix everything that's broken" prompts on larger projects.
v0's shareable links. v0 generates a shareable link for each component that you can send to colleagues for review. Bolt.new projects can be shared but the workflow is different (you share the Bolt project link). If your team used v0 links for design reviews, coordinate a new process.
Stack lock-in. v0 output is portable: you paste it anywhere. Bolt.new projects are more self-contained. Exiting the Bolt environment for production-grade setup requires more work than copying a component file from v0.
When NOT to switch
Stay with v0 if:
- You're building UI components that slot into an existing application. v0's output is cleaner to integrate into a project you already manage.
- Your team has an established backend stack and you don't need Bolt's scaffolding. v0 components are technology-agnostic enough to work with any backend you choose.
- You do design reviews by sharing v0 links with non-developers. The review workflow is simpler in v0.
- Your production application is already deployed and you're only generating individual components to add to it. Bolt.new's full-project model is overkill for this.
Bolt.new is the right switch when you want to go from zero to a deployed full-stack prototype without setting up a local environment. It's the better tool for hackathons, MVPs, and situations where "does this whole thing work end-to-end" is the question.
The migration works best if you treat it as a project restart rather than a component transfer. Bring your v0 components as inputs to Bolt.new's context, but let Bolt scaffold the architecture fresh rather than trying to reconstruct v0's output piece by piece. The full-stack environment is what makes Bolt.new worth using, and you only get the benefit of it if you let it manage the whole project.
