Lovable vs Bolt vs v0
These three get compared together but they are not really substitutes. Lovable builds full SaaS apps with Supabase auth and DB. Bolt builds general full-stack apps in-browser across many frameworks. v0 generates polished UI components in the Next.js + shadcn/ui ecosystem.
Lovable for full SaaS apps with backend, Bolt for general full-stack prototyping, v0 for UI and components in a Next.js + shadcn/ui world.
The tools at a glance
Lovable
by Lovable
AI app builder that ships full-stack apps with Supabase auth, database, and GitHub sync.
- Best for
- SaaS apps that need users, data, and hosting on day one.
- Standout
- Native Supabase: auth, Postgres, RLS, and storage are wired up automatically.
- Weakness
- Locked to Vite + React + Supabase — no framework choice.
- Pricing
- Free trial; Starter $25/mo; Pro $80/mo; Teams custom
Bolt.new
by StackBlitz
In-browser AI builder with a real WebContainer dev environment and broad framework support.
- Best for
- Rapid full-stack prototyping across many frontend stacks.
- Standout
- Live WebContainer IDE plus first-class Astro, Remix, Svelte, Vite, Next support.
- Weakness
- BYO backend and BYO design polish — flexible, but more wiring on you.
- Pricing
- Free tier (limited tokens); Pro $20/mo; Teams $30/seat
v0
by Vercel
AI UI generator focused on shadcn/ui components and Next.js, with strong design defaults.
- Best for
- Production-quality React components and screens.
- Standout
- Design taste and shadcn/ui-canonical output that drops into real Next.js apps.
- Weakness
- Not a full-app builder — no real backend, auth, or DB story.
- Pricing
- Free tier; Premium $20/mo; Team $30/seat
Key differences
Backend support
Lovable wires up Supabase auth + Postgres + storage automatically. Bolt scaffolds backend code but you bring the actual DB. v0 does not do backend — UI only. For anything with logged-in users and saved data, Lovable is the lowest-friction option.
Frontend stack
Lovable is Vite + React only. v0 is Next.js + shadcn/ui first-class. Bolt is the broadest — Astro, Remix, SvelteKit, Vite, Next all supported. Pick on what your team already runs.
Design quality
v0 wins clearly on design polish. Lovable's UI is competent shadcn/ui. Bolt's UI is generic — functional but unopinionated. For UI-led products, v0 output is what you want, even if you build the rest in Lovable or Bolt.
Scope of generation
v0 generates one screen or component at a time. Bolt and Lovable generate whole apps. Different shapes — v0 is for adding to a codebase, Lovable and Bolt are for starting one.
Deployment
Lovable deploys to hosted URL and pushes to GitHub. Bolt deploys via StackBlitz hosting or you export. v0 outputs code you push to Vercel. Lovable hides the most plumbing; Bolt and v0 expect a target.
Pricing
Bolt Pro and v0 Premium are $20/mo, Lovable Starter is $25/mo (most serious users go Pro at $80/mo). v0 stretches furthest on tokens because generations are small. Lovable feels priciest but does more per prompt.

Pick by use case
Building a full SaaS app prototype with auth and DB
Supabase wired in from prompt one. Bolt requires manual backend setup; v0 cannot do this at all.
Generating polished UI components
v0's shadcn/ui-canonical output and design taste beat both Lovable and Bolt for pure UI work.
Quick landing page demo
Fastest path to a beautiful single page. Lovable is overkill, Bolt looks more generic.
MVP that needs hosting included
Auth, DB, hosted URL, GitHub sync in one tool. Bolt and v0 leave hosting/auth to you.
App with complex backend logic
Bolt's WebContainer lets you write and run real server code in any framework. Lovable is locked to Supabase patterns; v0 is not in this game.
Designer prototyping production-quality UI
Single-component iteration with design polish. The other two are app-shaped, not designer-shaped.
Hackathon / weekend project
Cheapest, broadest stack support, fastest loop for a working prototype. Lovable runs out of credits faster on Starter.
Production-bound real product
For a real SaaS you intend to ship, Lovable + Pro covers the most of the stack. Pair with v0 for hero screens.
