Lovable vs Bolt: which is more secure?

Short answer

Neither is secure or insecure by default; both build apps whose data safety depends on Row Level Security (RLS) in a Supabase-style Postgres database. The difference is in the built-in checks. Lovable runs a free Quick scan every time you publish and offers a free on-demand Deep scan of your code. Bolt offers a database Security tab on all plans (the same checks as Supabase's Security Advisor) and a whole-project security audit on paid plans that doesn't use tokens. Both vendors say their scans don't guarantee security, so on either platform test with a second account and a signed-out request before launch.

Side by side

Automatic checkQuick scan on every publish: database rules, npm dependencies, unauthenticated MCP serverNone automatic; run the audit from the Publish menu

Database checkIncluded in the Quick scanDatabase Security tab, all plans, same checks as Supabase Security Advisor
Automatic fixes"Try to fix": 10 free fixes, renewing 24 hours after use, then creditsAudit fixes what it can; "Ask Bolt to fix" on the Security tab
Vendor caveat"cannot guarantee complete security"Flags open policies even when public access is intended; review each one

The risk is the same on both

Both generate browser code that talks to the database with a public key. That's by design; what decides safety is RLS. The classic failures are the same everywhere: a table with RLS off, a policy like using (true) on private data (Bolt's "RLS Policy Always True" warning), or a secret key placed in the frontend to make an error go away. Bolt's docs note it may write open policies when your site has no sign-in.

What to do on either platform

  1. Run the platform's scans and fix every Critical or Error finding.
  2. Check each private table has owner-scoped policies (examples).
  3. Test with two accounts and signed out.
  4. Make sure no secret key is in the frontend.

Where we can help

Free instant check: paste your URL at patchandship.com/check.html to scan your homepage's JavaScript for secret keys and security headers (no signup, nothing stored). Paid, fixed price per app: Database Check, $49; Security Fix, $149 (every critical issue on our checklist fixed within 48 hours of working access); Fix & Deploy, $249. Otherwise a full refund if you ask within 14 days of purchase (Refund Policy). AI agents run the checks and a human engineer approves every change. Not a penetration test or a security guarantee.

FAQ

Is Lovable more secure than Bolt?

Not inherently. Lovable scans automatically on publish; Bolt's full audit needs a paid plan. Your RLS policies matter more than which builder you picked.

Are the security scans free?

Lovable: both scans are free; fixes beyond 10 free ones use credits. Bolt: the database Security tab is on all plans; the project audit is on paid plans and doesn't use tokens.

What database do they use?

Lovable uses Lovable Cloud (its built-in backend) or your own Supabase project. Bolt has its own Cloud database, which uses the same checks as Supabase's Security Advisor, or you can connect Supabase.

Can I trust a clean scan before launch?

Treat it as a good sign, not proof. Both vendors say scans don't catch everything; a two-account test shows real behavior.
