How do I keep my app safe?

The minimum requirements for any app going live.

Automated bots scan public apps all day for leaked keys, open databases, public files, and unprotected endpoints. They do not need to know your app exists first. The free scan checks the same surface before they find it.

Run the free scan

Why it matters: A leaked service key can expose your database or let strangers spend money through your accounts.

How we check: LaunchGuard inspects the files your live app publishes for credentials and private keys.

The most dangerous bugs are behind login.

Traditional online scanners only see the surface. AI agents can test complex logic, but are expensive and dangerous to run against your live app, as they can delete data and cause costs for you.

LaunchGuard runs locally and it utilises your existing Claude Code subscription to test complex logic.

Pay once, use forever.
