Lovable app security: what to check before launch

What Lovable documents

Lovable describes two built-in checks: a quick scan that runs when you publish (database access, dependencies, MCP servers) and a deep scan (among other things access control, unprotected endpoints, unsafe inputs, secrets, payments, authentication). Together they make up the Lovable security scan.

The documentation also says that API keys and other secrets cannot be stored safely in client code; the “Secrets” feature exists for that. You manage Row Level Security under “More → Database → Manage → Policies”. The quick scan looks for tables without access control per row.

What you check yourself before launch

Five points a visitor can see from the outside:

• Does the shipped code contain a key that must not be public?
• Is Row Level Security switched on for every table that holds user data?
• Is there a legal notice (imprint) and a privacy policy?
• Does the page load fonts or tracking from third parties before consent?
• Are test and demo accounts removed or protected before launch?

Common mistakes

These mistakes follow from the Lovable documentation:

• Relying on the scans alone. Lovable itself says they find common security issues but cannot guarantee complete security and do not replace a thorough review.
• Running only the quick scan. It runs on every publish and covers a fixed set of checks; according to the docs, access control, secrets, payments and authentication are part of the deep scan.
• Pasting keys into the project chat or hardcoding them. Lovable detects keys in the chat and points you to “Secrets”; store them there.
• Never looking at the access rules. Under “More → Database → Manage → Policies” you can see every policy in your project.

We only name what Lovable documents. How secure your app is depends on what you built.
