Is Lovable Safe?
Lovable is safe to build with. What ships to production needs review · auto-generated RLS policies, exposed service-role keys, and permissive auth defaults are the top real-world issues we see in Lovable-built apps.
Known risks
- Exposed Supabase service-role keys · AI-generated code has been observed pasting the service_role key into client bundles · granting full DB admin access to anyone who opens DevTools.
- Missing or `USING (true)` RLS · AI often generates RLS policies that look secure but effectively allow any authenticated user to read every row.
- Auto-confirm signups by default · Lovable projects sometimes ship with email confirmation disabled, letting anyone create accounts with any email address.
How to make it safer
- Scan before publish · SimplyScan runs 51 checks against your Lovable app in 30 seconds · service-role leaks, RLS gaps, headers, XSS, and more.
- Enable email confirmation · In Cloud settings, require email verification before login unless you have a specific reason not to.
- Audit every RLS policy · Policies with `USING (true)` are almost always wrong. Scope every one to `auth.uid()` or a role check.
Frequently asked
Is Lovable safe for production apps?
Yes, provided you scan and review the generated backend before launch. The platform is solid; AI-generated Supabase config is where issues appear.
What's the #1 Lovable security issue?
Missing or overly permissive RLS policies. Every table on public schema needs RLS enabled and scoped policies.
Does SimplyScan check Lovable apps?
Yes · we have a dedicated Lovable scanner tuned for Supabase auth, RLS, and env-var patterns typical to Lovable projects.
