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.
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.
Line by line.
Swipe sideways to see both columns
| Lovable | v0 | |
|---|---|---|
| What it makes | A working app with data | Interface: screens and components |
| Who it is for | Founders without a coding background | Developers and designers with an existing project |
| Database | Supabase, connected out of the box | None, you arrange that yourself |
| Logins | Included | You build it |
| Stack | React and Tailwind, fixed | Next.js and shadcn/ui, fixed |
| Getting the code out | Syncs with your GitHub | Copy it or pull it in via the CLI |
| Going live | Own domain on their hosting | Deploy inside your own project |
| Findable in Google | Weak: browser app without separate pages | Fine, because it runs in your Next.js project |
| Where it stops | Permissions, server work, scale | Everything behind the screen |
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.
Can I build a complete product with v0?

Have your current site or tool scanned
You do not have to want to buy anything yet. Send what you have and I will tell you honestly what I would keep, what I would replace and whether that is worth the investment. Including when the answer is that you are better off doing nothing.
The scan is a first impression, not a security audit.
- 01Send a link to your site, your tool or your repository
- 02I look at speed, structure, data and security
- 03Usually within two working days you hear what I would replace and what that costs
Tell me what you
want to build.
A half-hour call. You get an honest answer about what it costs, how long it takes and whether building it is smart at all.
