// REPLIT SECURITY SCANNER
Is your Replit app safe for real users?
Replit Agent writes your app and deploys it in the same breath, so the gap between “idea” and “live on the internet” is minutes. That is powerful — and it means security review never happens. Secrets end up readable, the database is left open, and the app is public before anyone checks it. Veilguard scans your live Replit deployment, grades it A to F, and gives you the exact fix for every issue it finds.

// WHAT WE CHECK
What Veilguard checks in a Replit app
Exposed secrets and API keys
Keys that made it into your client bundle or committed files, where anyone can lift them. We check the deployed app and your git history.
Open database access
Replit DB, Supabase or Postgres left readable or writable by any visitor — the top cause of vibe-coded data leaks.
Authentication holes
Access checks that only run in the browser, missing rate limits on login, and weak password handling.
Injection risks
User input passed straight into database queries or shell commands — classic SQL injection the Agent doesn’t guard against.
Wide-open CORS
An API that any website can call, opening the door to cross-site abuse of your users’ sessions.
Missing HTTPS & security headers
The baseline protections attackers probe for first, often absent on fresh deployments.
// THE GAP
Why Replit apps ship exposed
When building and deploying are a single action, there is no natural moment to ask “is this safe to be public?” Replit Agent makes reasonable functional choices, but it does not harden your app or warn you about what it left open. Veilguard adds the missing checkpoint — after you ship, before anyone gets hurt.
// HOW IT WORKS
Scan. Understand. Fix.
Scan
Paste your app’s link. No install, no signup — just the URL you already share with customers.
Understand
A clear A–F grade and every issue in plain English: what it is, why it matters, and how bad it really is.
Fix
The exact fix for each issue — copy-paste code or a ready-made prompt for your AI. Then we keep watching.
// FAQ
Replit security, answered.
Does Veilguard work with Replit deployments?
Yes. Paste your live Replit URL and we scan it from the outside in about 60 seconds. Connect GitHub or your database read-only for a deeper audit that includes secrets in your git history.
Will it catch secrets committed to my Repl?
With a read-only GitHub connection, yes — we scan your git history for keys and tokens that were committed and are still exposed, then tell you exactly which to rotate.
Do I need to understand the fixes?
No. Every issue comes with copy-paste code or a ready-made prompt you can give back to Replit Agent to apply for you.
