Replit
Is Replit secure?
Replit is not a security product, and it is not automatically unsafe. A Replit deployment is an ordinary website. The page, its same-origin scripts, and the headers from that host are what a visitor receives, and what this scan reads.
The Replit API, the workspace, and secrets that exist only in Replit's server environment are outside the fetch.
A useful check is the deployed URL
Paste a URL you own. The scan is passive. It does not log in, brute-force paths, or query a database. Supabase Row Level Security and Firebase security rules are not read. Those stay marked as coming soon.

Is Replit secure?
Replit is a way to build an app. The security question is about the URL you publish. A Replit deployment is an ordinary website. The page, its same-origin scripts, and the headers from that host are what a visitor receives, and what this scan reads.
What does a free scan cover?
The public page, up to 10 same-origin scripts, headers, cookies, robots.txt, sitemap.xml, homepage links, and five paths: /.env, /.env.local, /.env.production, /.git/HEAD, and /.git/config.
What will a scan of a Replit URL miss?
The Replit API, the workspace, and secrets that exist only in Replit's server environment are outside the fetch.
Scan a URL you own
The same free check as the homepage. You confirm the app is yours before it runs.
