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.

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.

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.

How do I check a Lovable project for security vulnerabilities?

Open the project's Security view (or the workspace Security center) to run Lovable's built-in scan for exposed secrets, missing RLS, and vulnerable dependencies, then ask Lovable to fix what it flags.

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?

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.

Can users access other users' information?

Q: 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.

Q: 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.

Short answer

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.

Why this is a database problem, not a UI problem

Hiding another user's data in the interface (e.g. only showing "your" orders in a list) does nothing if the underlying query could still return anyone's rows when called directly. The fix has to sit in row-level security policies at the database level, not in what the app chooses to display.

The pattern that works

A correct RLS policy on a table like orders restricts every read and write to rows where user_id = auth.uid(), regardless of what the client requests. That way, even if someone inspects network requests and tries to change an ID in the request, the database itself refuses to return another user's row.

How to test it yourself

Create two real test accounts.
Log in as user A, note an internal ID (e.g. an order ID) from the browser's network tab.
Log in as user B and try to fetch that same ID directly (e.g. by editing a URL or replaying a request).
If user B can see or edit user A's data, the RLS policy is missing or wrong.

A prompt that helps

Review the RLS policy on the orders table and confirm it restricts all reads and writes to rows owned by the authenticated user, not just to what the app's queries currently ask for.

What usually goes wrong

Developers filter by user ID in the front-end query (select().eq('user_id', currentUser.id)) and assume that's enough — but that filter is just a convenience, not security, since a modified request could omit it. The RLS policy, not the client-side filter, is what actually enforces the restriction. See /questions/how-do-i-check-supabase-rls to verify yours, and /questions/how-do-i-protect-admin-pages for the equivalent problem with role-gated pages.
