Are Lovable websites secure?

Lovable includes built-in security scanning and API-key protection, but real security also depends on you setting up row-level security and role checks correctly — it isn't automatic just because you used Lovable.

How do I run a security audit on Lovable?

Open your project's Security view in Lovable to see automated scan results, then ask Lovable in chat to review RLS policies, role storage, and any exposed secrets in detail.

How do I secure a Lovable app before launch?

Before launch, verify RLS on every table, move roles into a dedicated user_roles table, confirm no secrets sit in front-end code, and run Lovable's Security view scan.

How do I check Supabase RLS?

Ask Lovable to list every table and its row-level security status and policies in plain language — Lovable Cloud users don't have Supabase dashboard access, so this has to go through chat.

Can users access my database?

Only through the access rules you (or your row-level security policies) allow — Lovable Cloud's database isn't publicly browsable, but a table without RLS enabled is effectively open to anyone with your app's public key.

Can users access other users' information?

Only if your row-level security policies are missing or too permissive — with correct RLS, a query for 'my orders' can only ever return rows owned by the logged-in user, regardless of what the front end sends.

How do I protect admin pages?

Check the user's role server-side (in the database query or Edge Function) using a dedicated user_roles table — hiding an admin link in the navigation menu doesn't stop someone visiting the URL directly.

How do I protect API keys?

Never put API keys in front-end code — store them as secrets used only inside server functions (Edge Functions), where the browser never sees them.

Where should secrets be stored?

In your project's server-side secrets store, used only inside Edge Functions — never in front-end code, client-side environment variables, or committed to your Git repository.

How do I secure Edge Functions?

Verify the caller's identity and role inside the function itself, validate all input, use secrets rather than hard-coded keys, and don't assume the front end already checked permissions.

How do I prevent database abuse?

Combine row-level security with rate limiting on writes, input validation, and CAPTCHA or similar checks on public forms — RLS stops unauthorised reads/writes, but it doesn't stop a legitimate-looking user from hammering an endpoint.

How do I rate-limit an API?

Add per-user or per-IP request limits inside your Edge Function (or via a Postgres table tracking recent requests), since Lovable doesn't apply rate limiting to your custom endpoints automatically.

Add a CAPTCHA (e.g. Cloudflare Turnstile) to public forms, validate inputs server-side, and rate-limit submissions — client-side-only checks like a hidden field are easy for real bots to bypass.

How do I prevent spam registrations?

Verify email addresses on sign-up, add a CAPTCHA to the registration form, rate-limit sign-up attempts per IP, and check the token server-side before creating an account.

How do I check for exposed environment variables?

Ask Lovable to search your codebase for hard-coded API keys and secrets in front-end files, then move anything sensitive into a server function or edge function.

Is my Supabase anon key safe to expose?

Yes. The Supabase anon key is meant to be public — it identifies your project, it does not grant access on its own. Access is controlled by row-level security (RLS) policies, not by hiding the key.

What security checks should I do before launching?

Run Lovable's Security scan, verify RLS on every table, confirm secrets are server-side, check auth flows and admin permissions, and re-test payments before you Publish.

How do I make Lovable perform a security review without changing anything?

Short answer

Explicitly tell Lovable to run in read-only review mode — ask it to report findings only and not touch any code, then decide what to fix yourself.

Why you need to say it explicitly

By default, Chat and Build mode in Lovable will act on requests — if you ask it to "check for security issues" it may start fixing things as it finds them, which can change working behaviour you didn't want touched. To get a pure report, you need to say so clearly, and ideally use Plan mode, which is designed to think through and describe changes before any code is written.

How to do it

Switch to Plan mode if you want a discussion-first pass with no code execution at all.
In Chat, be explicit:

Do a full security review of this project. Check RLS policies on every table, look for exposed secrets in front-end code, and check that admin-only actions are enforced server-side. Report every issue you find with the affected file or table, but do not change or fix anything yet.
Read the report, then decide which fixes to apply — either one at a time, or batch the safe ones together.
If you do want fixes applied, ask for them individually and check the diff before accepting.

What to expect back

A useful review names each finding, the affected table/file, why it's a risk, and the fix — not just "looks secure" or a wall of generic advice.

What usually goes wrong

Asking a vague "is this secure?" — you'll often get a shallow answer. Ask for the specific checks (RLS, secrets, admin permissions, dependency risk) by name.
Forgetting that Build mode messages consume the same credit balance as other tasks even if you only wanted a report — Plan mode is worth using here.
Applying every suggested fix in one go and then struggling to tell which change broke something if a regression appears; fix and re-test incrementally instead.
