v0 vs Lovable: A UI Generator and an App Builder, Side by Side

ComparisonHype Stack and v0 and Lovable, side by side.

All stacks

By Maciej Pyrc, who maintains Hype Stack.Published .

One of these makes screens. The other makes apps. Most of the confusion in this comparison comes from expecting either to do the other's job.

Comparisons of v0 vs lovable tend to score them on the same card, and the scores come out odd: v0 wins on design and loses on backend, Lovable wins on backend and loses on polish. That is not two products at different quality levels. It is two products with different scopes, and the useful question is which scope matches the thing you are trying to make, and whether you might want both.

v0 is Vercel's generator. You describe a screen, or paste a screenshot, and it returns React with Tailwind and shadcn/ui components that look like someone designed them. It has grown toward whole Next.js projects and it deploys to Vercel in a click, but the screen is still what it is best at. Lovable starts from the other end: a prompt becomes a running app with a database, auth and hosting, and the screens are competent rather than striking.

What each one is for

v0
Lovable
Scope
A component, a page, or a Next.js project. Strongest when you already have an app to put it in.
The whole application: screens, data, auth and a URL, in one place.
Visual quality
The best in this category. shadcn/ui and Tailwind, with a design mode for small edits.
Clean and usable, rarely striking. The strength is that it all works together.
The backend
Not the point. Integrations exist, but you are expected to bring the API and the data.
Bundled: Lovable Cloud by default, or your own Supabase project if you connect one.
Who it suits
Developers in React or Next.js who want the markup done well and will own the rest.
Founders and non-developers who want a working product without seeing the code.
Where it runs
Vercel, naturally. The code is standard enough to run elsewhere.
Lovable's hosting, with GitHub sync for the frontend on the paid plans.
Cost shape
Credits per generation, with Vercel's hosting separate.
Credits per message, plus the platform's backend and hosting usage once live.

Read the first row twice. Everything else on the card follows from it. v0 produces something you put into an application. Lovable produces the application. Asking v0 for a multi-tenant SaaS with billing is asking a very good screen generator to be a backend, and asking Lovable for a pixel-exact marketing page is asking an app builder to be a designer. Both will try. Neither is what you paid for.

Using both, which is what many teams do

The pairing that works is the obvious one: Lovable for the application, v0 for the screens that have to look designed. The landing page, the pricing page, the one dashboard view a customer sees every day. v0 generates the component, you paste it into the Lovable project through the GitHub sync, and the agent wires the data.

The two-tool loop

  1. Build the app in Lovable

    Data, auth, the screens that merely need to exist. Get a URL.

  2. Design the screens that matter in v0

    Paste a sketch or a competitor's page. Iterate in design mode until it looks right.

  3. Move the component across

    Through the GitHub export, into the Lovable repo, then ask Lovable's agent to connect it to real data.

    The styling survives. The data wiring is a new prompt.

This loop has a cost nobody mentions until they hit it. Two agents now own one codebase, with two sets of conventions, and the component from v0 uses whichever shadcn version and Tailwind config v0 preferred that week. On a small app nobody notices. On a growing one, the seams are where the bugs live.

The backend decides the rest

v0 is honest about not being a backend. Lovable is a backend, but the shape of it matters more than most comparisons admit. New Lovable projects get Lovable Cloud: Supabase's open-source stack, run by Lovable, without a connection string or a service key in your hands, and without a supported path to a Supabase project you own. Connecting your own project is fully supported, but it is a choice made at the start, before there is data.

So the question under "v0 vs Lovable" for anyone building a business is: where will the data live in a year, and who holds the keys? v0 leaves that entirely to you, which is a burden on day one and a relief in month six. Lovable answers it for you, which is the reverse.

Which one, then?

v0

You have an app, or will build one, and you want the screens done properly.

  • Best output in the category for anything a customer looks at
  • Standard React and shadcn/ui, so the component drops into any codebase that uses them
  • Bring your own backend, auth and billing; it does not pretend otherwise
Lovable

You do not have an app, cannot build one, and need a working product with a login by tonight.

  • The bundled backend is the whole reason it feels finished
  • Connect your own Supabase project at the start if the data has to be yours
  • Expect to supplement the design with v0 or a designer once there are customers

Different jobs. The mistake is picking one for the other's job and concluding the tool is bad.

Where Hype Stack lands

Hype Stack is neither a generator nor a builder. It is a template you install locally: React with TanStack Router, Tailwind and shadcn/ui on the frontend, which is the same component vocabulary v0 speaks, with a Hono backend on Postgres behind it and packs that add auth with organizations, Stripe billing and an admin app as source files. There is no agent inside it. You bring Claude Code, Cursor or Codex, and the repository ships the rules files and an MCP server that keep them inside the conventions.

That puts it in an interesting spot relative to both products. A v0 screen pastes into a Hype Stack frontend with almost no translation, because the primitives are the same, and the data wiring is a typed SDK generated from the backend routes rather than a prompt. And the thing Lovable bundles, the backend, is the thing the template ships in your own dashboard: Prisma migrations in git, a Postgres URL you hold, auth and billing already built.

The path if you want to own it

Screens from v0, straight in

Generate the page in v0, paste the component into the frontend app, and point your coding agent at the SDK for the data. Same shadcn/ui, same Tailwind, no second convention.

The backend Lovable was hiding

Hono routes, Prisma schema and Kysely queries on a database you can connect to. Organizations, subscriptions and the admin screens arrive as packs.

One agent, one repo

Instead of two platform agents sharing a codebase, one coding agent works in a repository with rules files. The seams go away because there is one set of conventions.

What the template does not do is worth saying plainly. It does not generate a screen from a screenshot, so v0 stays useful. It does not give you a URL after a sentence, so Lovable's first hour stays faster. The first hour here is installing Node, running Postgres in Docker, and one CLI command. After that hour, there is no platform to outgrow.

The template and packs are below, with the install command. If the question was really "which builder", read Bolt vs Lovable next; if it was "how do I stop renting", the Lovable alternative page covers the move.

What is Hype Stack?

Every product starts with the same month of work nobody pays you for: sign-up and login, teams and permissions, taking payments, notifications, an admin panel to run the business. Hype Stack is that month, already built and tested. Start from the free open-source app, add the pieces you need with one command, and keep going on the part that is actually your idea.

Everything lands as real code in your own repository, so there is nothing to rent and nothing anyone can switch off. For the engineers: React 19, Hono, Postgres, and a desktop build, typed end to end.

See it running.

Curated starters built on this stack: a layout, feature packs, a theme, and bonus pages. The previews are recordings of the real apps.

Two ways to install.

Same features underneath. Either command resolves what the packs need, copies the source into your repo, and merges the Prisma schema.

Take a template

A landing page, a design system, a themed layout, and the features already wired in. Rebrand it, put your product in the middle, ship.

Compose your own design

Your design and your choices, without rebuilding auth, billing, or notifications. Tick the packs you want and the CLI wires them into the open-source starter.

$npx @hype-stack/cli compose
Browse packs

What each pack gives you.

Source code, not a dependency. Every pack lands in your repository across the surfaces the feature touches.

Authentication, organizations, roles, sessions, and a full admin app, powered by Better Auth on your own Postgres.

  • Email & Google login
  • Organizations & members
  • Roles & permissions
  • Admin app & dashboard

Questions, answered.

Lovable. It produces the whole application with a database, auth and a URL. v0 produces a component, a page, or a Next.js project with the backend left to you, and it is at its best when there is already an app to put the screen in.
