Lovable and Bolt.new are the two leading AI app builders for non-developers. We tested both by building the same applications to compare quality, workflow, and value.
Quick Verdict
Choose Lovable if: You need a full-stack app with authentication and database — Supabase integration is class-leading.
Choose Bolt.new if: You want frontend-focused apps with maximum flexibility in framework choice and deployment.
What We Built (Both Tools)
- A task management web app with user login
- A simple CRM for tracking contacts
- A public-facing landing page with a contact form
Frontend Quality
Winner: Tie
Both Lovable and Bolt.new generate excellent React + Tailwind UIs. Design quality is professional from both — better than average developer frontend work.
Bolt.new has slightly more framework flexibility (also supports Vue, vanilla JS), while Lovable defaults to React/shadcn/ui.
Backend and Database
Winner: Lovable
This is the most significant difference:
Lovable + Supabase:
- Automatic database schema generation
- Row-level security policies generated correctly
- Authentication (email, Google, GitHub) works out of the box
- Edge functions for serverless logic
- File storage included
Bolt.new:
- Limited backend support
- Typically requires manual backend configuration
- Works best for frontend-only or very simple full-stack apps
- Supabase and Firebase integrations exist but require more manual setup
For building complete web apps that users log into, Lovable’s Supabase integration is significantly more capable.
Authentication
Winner: Lovable
Lovable generates working authentication flows reliably. We tested:
- Email/password signup + login ✅
- Google OAuth ✅
- Password reset ✅
- Protected routes ✅
Bolt.new authentication setup requires more manual work and is less reliable on first generation.
Iteration and Refinement
Winner: Bolt.new (slight edge)
Both tools support conversational iteration. Bolt.new’s iteration felt slightly more responsive for visual changes — “move this button to the right” type refinements.
Lovable is better for functional changes — “add user profile settings” or “add email notifications” — where database changes are involved.
Code Quality
Winner: Tie
Both generate clean, readable TypeScript React code. Both use modern patterns (hooks, context, etc.). Neither generates production-hardened code without review.
Key difference: Lovable’s generated code interacts with Supabase in a more structured way. Bolt.new code is slightly more self-contained.
Deployment
| Feature | Lovable | Bolt.new |
|---|---|---|
| One-click deploy | Vercel | Netlify |
| Custom domain | Yes | Yes |
| Backend hosting | Supabase (separate) | Limited |
| Database hosting | Supabase | DIY |
Lovable’s deployment story is cleaner for full-stack apps — frontend on Vercel, backend on Supabase, both managed.
Code Export and Ownership
| Feature | Lovable | Bolt.new |
|---|---|---|
| Full code export | Yes | Yes |
| Continue in VS Code | Yes | Yes |
| Vendor lock-in | None | None |
Both give you full ownership of generated code. You can export and continue development anywhere.
Pricing
| Plan | Lovable | Bolt.new |
|---|---|---|
| Free | 5 projects | Daily limits |
| Starter | $25/month | $20/month |
| Pro | $75/month | $40/month |
Bolt.new is slightly cheaper. For the full-stack capability Lovable provides, the price difference is justified.
Real-World Results
Task Manager with Login:
- Lovable: Fully functional in 10 minutes (auth + tasks + database)
- Bolt.new: Good frontend, manual backend setup required (~30 minutes total)
Landing Page:
- Bolt.new: Faster iteration on visual design
- Lovable: More consistent first-generation quality
Who Should Choose Which
Choose Lovable if:
- You need a complete SaaS-style app with user accounts
- Authentication is required
- Database is needed
- You want the most complete no-code-to-production pipeline
Choose Bolt.new if:
- You’re building frontend-heavy apps (portfolio, landing pages, tools)
- You want more flexibility in tech stack choices
- Budget is the primary concern
- You’re comfortable setting up backend separately
The Honest Bottom Line
For non-developers building real applications people will log into, Lovable is the better choice — the Supabase integration genuinely works and produces complete, deployable applications.
For frontend-focused projects and rapid prototyping, Bolt.new is faster and more flexible.
Neither replaces a real engineering team for complex, production-scale applications.
