Comparison

Lovable vs v0:
app or interface?

They get mentioned in the same breath and they do something fundamentally different. Lovable tries to make a working application, database included. v0 makes interface: screens and components that look right immediately. Miss that difference and you pick the wrong one, and only notice two weeks later.

The short answer

If you want something people log into and leave data in, start with Lovable: Supabase sits underneath, so a database and logins are there from the start. If you want a screen, a landing page or a component to drop into an existing project, v0 is faster and better looking. v0 belongs with a developer who already has a project; Lovable with someone who does not. Once it genuinely has to go live, both leave out the same thing: permissions on your data, server-side work and an environment that runs independently of the subscription.

The reasoning

Where those differences come from.

v0 does not know your data, and that is intentional

v0 comes from Vercel and is built to generate interface for Next.js projects. It knows nothing about your database, because that is your project. You get screens that look right immediately and that you paste into an existing codebase. Ask v0 for a complete product and you get a complete-looking front end with nothing behind it, which is exactly the trap non-technical users fall into.

Lovable picks the whole stack for you

Lovable always builds the same thing: React, Tailwind and Supabase. That means logins and a database are there straight away, which is why people without a coding background have something working in an afternoon. The price is that you stay inside those choices, and that the permissions on your data are not set up correctly by default.

Both deliver code, not a product

With both you can get at the code. What you do not get is everything around it: environment variables, migrations, tests, a build process and someone who knows which part matters. That is not a criticism of the tools; it is the difference between a prototype and something customers depend on.

In practice people use them together

The combination I see most: Lovable for the skeleton and the data, v0 for a few screens that really have to look good. That works fine, as long as you realise you then have two half foundations and no production environment.

And then it has to go live

The moment real users arrive, the question changes. Who is allowed to see which row in the database, what happens when two people save at once, where does it run when the subscription stops. That is the work I do: the prototype stays, the foundation underneath gets built.

Frequently asked questions
Can I build a complete product with v0?
The screens yes, the rest no. v0 generates interface for a project you already have. Without a database, logins and server-side work you have a demo that looks good, and that is exactly where people get stuck.
So is Lovable better?
For someone without a code project, yes, because you get something working faster. For a developer with an existing Next.js codebase, v0 is more useful because it drops straight into that project.
Can I move from v0 to a real project?
Yes, and it is the easier of the two: v0 components are just React in a Next.js project. What has to be added is everything behind the screen: data, permissions, payments and a deploy that does not fall over.
What does making such a prototype production-ready cost?
That depends on what is there. I read what exists first and say what is usable before anything gets rebuilt; in most cases the screens and the data model stay and the work sits in the foundation underneath.
Does my code stay mine?
Yes. Everything I deliver sits in your repository, with hosting on your account. You are not tied to anything, including me.
