Lovable vs Bolt.new

Lovable produces more portable code and gets closer to production. Bolt.new is faster for demos. Both need security review — Lovable for Supabase RLS, Bolt for everything.

Both Lovable and Bolt let non-technical users build apps from natural language prompts. They're the most popular 'describe your app and get code' tools. But they produce very different output and have different strengths when it comes to going from prototype to production.

Head-to-head comparison

Backend integration

Lovable

Lovable

Tight Supabase integration — database, auth, storage, and realtime out of the box. The backend exists and works, just needs security hardening.

Bolt.new

Backend is often minimal or absent. Frontend-heavy prototypes that may use mock data. A real backend usually needs to be built from scratch.

UI quality

Lovable

Lovable

Clean UI with shadcn/ui and Tailwind. Consistent design system. Components look polished.

Bolt.new

Good UI but less consistent. Styling varies depending on the prompt. Can produce impressive demos but design cohesion varies.

Security

Tie

Lovable

Critical Supabase RLS issues — data is often unprotected. Has auth but authorization is incomplete. Most dangerous when you think it's secure but it's not.

Bolt.new

Usually no security at all — no auth, no validation, hardcoded keys. At least you know it's not secure.

Speed

Tie

Lovable

Very fast — working app in minutes from a prompt. Iterative refinement through conversation.

Bolt.new

Extremely fast — full prototypes in the browser in minutes. WebContainer means instant preview.

Export and portability

Lovable

Lovable

Exports to GitHub. Clean React/Vite codebase. Can be deployed to any hosting platform.

Bolt.new

Downloads from WebContainer. May have Bolt-specific dependencies or configurations that need cleanup.

Iteration in the tool

Lovable

Lovable

Good conversational iteration. Can refine features, fix issues, and add pages through chat. Maintains context well.

Bolt.new

Quick iteration in the browser. But complex changes sometimes cause regressions — fixing one thing can break another.

Code quality

Lovable produces more complete, better-structured code with a real backend (Supabase). Bolt produces faster prototypes but they're more frontend-focused and need more work for production. Lovable apps are closer to production-ready in terms of features but have critical security gaps in Supabase configuration.

Security

Different kinds of risk. Lovable apps look more secure (they have auth, a database, user accounts) but often have invisible data exposure through missing RLS. Bolt apps obviously have no security and everyone knows it. Lovable's false sense of security is arguably more dangerous because founders might ship without a review.

Which should you choose?

Choose Lovable if...

Building full-featured apps with user accounts, data persistence, and real backend functionality. Best when you need a complete app, not just a UI.

Lovable services

Choose Bolt.new if...

Rapid prototyping and demos. Best when you need to show something working quickly and are prepared to rebuild the backend for production.

Bolt.new services

The bottom line

Lovable for complete apps, Bolt for fast demos. If you're building something you intend to launch, Lovable gets you closer. But both need professional security review before going live — Lovable especially for Supabase RLS, Bolt for everything.

Frequently asked questions

Which is better for a SaaS MVP?

Lovable. It gives you user auth, a database, and persistent data storage out of the box. These are essentials for any SaaS. Just make sure to configure Supabase RLS before sharing with real users. Bolt is better for landing page demos and UI prototypes.

Can I use both together?

Not really — they produce different codebases and architectures. Pick one for your project. If you need a quick demo, start with Bolt. If you need a functional MVP, start with Lovable. Don't try to merge output from both.
