Most security tools scan your code. Preflyt scans what actually matters - the live deployment. After you push to production, Preflyt checks your public URL for the security mistakes that slip through: .env files served publicly with database passwords, open Redis and Postgres ports, missing HSTS...

As answered by people managing Preflyt.dev and DevFinanceTools.
Preflyt.dev's answer
Preflyt scans the live deployment, not the code. Most security tools analyze source code or dependencies. Preflyt checks what's actually exposed on the public internet - the same perspective an attacker has.
Preflyt.dev's answer
Zero friction. Paste a URL and scan instantly - no account, no setup, no agents on your server. Also works from the terminal with npx (no install) and with AI coding agents via a skill file. Most alternatives require signup, onboarding, or complex configuration
Preflyt.dev's answer
Indie developers, solo founders, and small teams who ship fast and want a quick safety check before users find the problems. Especially relevant for developers using AI coding tools like Cursor and Claude Code who deploy frequently
Preflyt.dev's answer
Kept seeing the same deployment mistakes in live web apps - .env files with database passwords served publicly, open database ports, missing security headers. These aren't code bugs, they're deployment oversights. Built Preflyt to catch them in 30 seconds.
Preflyt.dev's answer
Preflyt is early stage with 80+ developers using it organically. Focused on indie developers and small teams right now
