Is my app secure? Pick your builder

AI app builders make it quick to ship, and just as quick to leave a database open or a secret key in the browser. Each page answers the question for one builder: how its apps are usually built, what tends to go wrong, what its own security tools cover, and a short checklist.

• Is my Lovable app secure?

  Your Lovable app can be secure, but it isn't secure by default: Lovable gives you the building blocks (a Supabase-based backend, Secrets and a built-in Security view), and whether your users' data is protected depends on how your tables, policies and keys are set up.

• Is my Bolt app secure?

  A Bolt app can be secure, but Bolt doesn't make it secure for you: your data is protected by your database's access rules and by keeping secret keys in server functions, and both are easy to get wrong when an AI writes the code.

• Is my Cursor app secure?

  Cursor is a code editor, so whether your app is secure depends on the stack you and Cursor's agent chose and how it's deployed; Cursor doesn't host your app or add a security layer to it.

• Is my Replit app secure?

  A Replit app can be secure, and Replit gives you useful tools (Secrets, a Security Center and pre-publish scanning), but they can't catch everything: API routes that skip auth checks and keys that leak into the frontend are still yours to fix.

• Is my v0 app secure?

  A v0 app can be secure, but v0 doesn't add a security layer for you: it generates a Next.js app, and your data is only as safe as your database's access rules and how your environment variables are split between server and browser.
