Comparison
Lovable vs Bolt.new
Bolt.new (StackBlitz) and Lovable both target prompt-to-fullstack web app generation. They differ on runtime model, hosting, and which AI patterns they encourage.
Lovable
Lovable generates a React frontend and provisions Supabase. Best for non-developers who want a hosted app at the end.
Choose Lovable if
- You want a hosted app you can share with users
- You prefer prompt-driven over code-driven iteration
- You're a non-developer
Bolt.new
Bolt.new runs apps inside a browser-based WebContainer, with a Supabase integration. Best for quick prototypes you can iterate on in-browser.
Choose Bolt.new if
- You want to iterate on code in the browser
- You're comfortable with the WebContainer runtime
- You want quick prototypes for sharing
Side-by-side comparison
| Category | Lovable | Bolt.new |
|---|---|---|
| Runtime | Standard React + Supabase | WebContainer (browser) |
| Backend | Supabase | Supabase |
| Code export | Frontend yes, backend partial | GitHub |
| Hosting | Lovable-hosted | Bolt.new |
| AI iteration | Yes (prompt-driven) | Yes ('Attempt Fix') |
| Token burn | High on regression loops | High on bug fixes |
| Best for | Non-developer prototyping | Engineer-friendly prototyping |
Whichever you pick, we audit the output.
Both ship apps with secrets in client bundles, missing Supabase RLS, and unverified Stripe webhooks. We audit and migrate from either to your own infrastructure. From $500.
Frequently asked questions
- Which has better security defaults?
- Neither has good security defaults. Both ship with Supabase RLS commonly disabled, secrets in client bundles, and Stripe webhooks without signature verification. A manual audit is non-optional before production.
