Lovable vs v0 vs Bolt: Design-to-Code AI Compared

Last updated: August 2026

These three get compared constantly and treated as interchangeable, which they aren't. The difference isn't output quality — it's scope. One builds components, one builds applications, one builds a development environment.

Pick based on how much of the stack you need, not on which demo looked best.

Head to head

	v0	Lovable	Bolt.new
Scope	Components, pages	Full-stack apps	Full-stack apps
Back end	No	Yes (Supabase)	Yes
Auth & database	No	Built in	Configurable
Code ownership	Copy out	Full repo, GitHub sync	Full export
Runs in browser	Preview only	Preview	Full dev environment
Framework	React, Next.js, Tailwind	React, Tailwind, Supabase	Multiple
Best for	Adding to an existing app	Building a product	Prototyping and debugging

v0 — components, done properly

v0 from Vercel is the most focused of the three and the best at what it does. Describe a component or a page, get React and Tailwind built on shadcn/ui, refine it conversationally, paste it into your project.

The shadcn/ui foundation is the real advantage. It's already the default in a large share of React projects, so output drops into existing codebases without a styling fight.

Where it stops: no back end. v0 gives you the front end and nothing else. If your thing needs users and data, v0 is one part of the solution.

Use it when: you have a codebase and need to add interface to it.

Lovable — the whole application

Lovable generates a complete product: React front end, Supabase back end, authentication, database schema, the lot. It syncs to GitHub, so you own a real repository rather than a hosted artefact.

That last point is what separates it. Many AI builders keep you inside their platform. Lovable hands over the code, which means the thing you build can outlive your subscription.

Where it stops: it's not a design tool. You describe what you want and adjust in conversation; you don't drag things around a canvas. Getting a specific visual result takes more iteration than drawing it would.

Use it when: you need a working product with accounts and data, and you'd rather not stand up the back end yourself.

Bolt.new — the fastest loop

Bolt.new runs a complete development environment in the browser. Generated code executes immediately, you see real errors, you fix them in place. No local setup, no context switching.

For prototyping and for debugging what the AI produced, this is meaningfully faster than the others. The trade is that heavier projects strain the browser environment.

Use it when: you want to try something, see it run, and iterate fast.

The things all three share

The last 20% is the expensive part. All three get you to something impressive quickly. Refining that into something genuinely production-quality takes roughly as long as it always did.

Prompt fidelity costs time. If you know precisely what you want, describing it repeatedly can take longer than building it. These tools are strongest when the destination is fuzzy.

They converge. v0 keeps adding back-end features, Lovable keeps improving front-end control. Don't build a workflow that assumes today's boundaries hold.

Which one?

• Adding a component to an existing React app → v0
• Building a product from zero, needs auth and a database → Lovable
• Prototyping something to see if it works → Bolt.new
• You want to own the repository → Lovable
• Your team already uses shadcn/ui → v0
• You want visual, canvas-based control → none of these. Look at Onlook or Subframe instead.
