Is your AI-built app secure? Platform guides

The platforms are usually solid. The app you built on top of them is a separate question. Pick yours to see what apps on that stack tend to miss, where the fix goes, and how to check your live site.

• Is your Lovable app secure?Lovable itself is a reasonable place to build, and it hosts your app over HTTPS. Whether your app is secure depends on your Supabase setup: row level security on every table, and no secret or service_role key in the front end.
• Is your Supabase app secure?Supabase is a secure platform: it runs Postgres for you, handles auth, and encrypts traffic. Your app is secure when every exposed table has row level security with sensible policies, and the service_role or secret key never leaves your server.
• Is your Replit app safe?Replit is a safe place to write and host code. The risks sit in your app: API keys typed into source files instead of the Secrets pane, source code that other people can view, and an Express server shipped without secure cookies or security headers.
• Is your Netlify site safe?Netlify is a safe host: it provisions HTTPS certificates, serves your files from its CDN and keeps your build environment variables out of the browser unless your code puts them there. What it leaves to you is security headers, keeping secrets out of the front end build, and the code in your functions.
• Is your Vercel app safe?Vercel is a secure host: HTTPS, certificates and the edge network are handled for you. Your app is safe when secrets stay out of NEXT_PUBLIC_ variables, your server routes check who is calling, and you set the security headers Vercel does not add for you.
• Is the app Claude Code built secure?Claude Code is safe to use: it runs in your terminal and asks before editing files or running commands unless you allow it. The app it builds is only as secure as the review it gets, so check for keys in front end code, env files that reach the deploy, and missing security headers before you ship.
• Is the app Cursor built secure?Cursor is a safe editor to use, with the usual care about which commands you let its agent run and which files it can read. The app you build with it is a separate question: check for secrets in the front end, env files that reach your deploy, and missing security headers before you ship.
• Is your Base44 app safe?Base44 runs the database, login and hosting for your app, so a lot of the infrastructure work is done for you. What stays your job is who can see the app and its data, and keeping third party API keys out of the pages your visitors load.
• Is your Bolt app secure?Bolt.new is a safe tool to build with. A Bolt app is secure when its Supabase tables have row level security, no secret key sits in a VITE_ variable, and the site it deploys sends security headers.
• Is your v0 app secure?v0 is Vercel's app builder, and it generates Next.js apps that deploy on Vercel, which is a secure host. Your v0 app is secure when no secret sits in a NEXT_PUBLIC_ variable, every server action and route handler checks who is calling, and you add the security headers Next.js does not set by default.
• Is your Firebase app secure?Firebase is a secure platform, and the API key in your web config is meant to be public. Your app is secure when Firestore, Realtime Database and Storage rules only allow what each user should do, and no service account key or other secret ends up in your front end.
• Is the app Windsurf built secure?Windsurf is a safe editor to use, as long as you control which commands its Cascade agent runs on its own. The app you build is a separate question: before you deploy, check for secrets in front end code, env files in git or the build output, and missing security headers and cookie flags.
