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 and CSP headers, exposed .git repositories, admin panels without protection, and debug endpoints left on. Run it from your browser at preflyt.dev or from your terminal with npx preflyt-check. Takes about 30 seconds, no signup needed. Every scan generates a shareable report with a unique link - send it to your team, post it on social media, or keep it as a record. Preflyt also works with AI coding agents. Drop a SKILL.md file in your project and agents like Cursor, Claude Code, GitHub Copilot, OpenClaw, and Cline automatically scan after every deploy. No CI/CD configuration needed. Built for indie developers, vibe coders, and small teams who ship fast and want a quick safety check before users find the problems first. Free for 3 scans. Pro at $9.99/month for unlimited scans and CLI access.
ExpressJS Preflyt.devPreflyt.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

Casbin provides an external policy engine if your permission model grows complex enough that a centralized JS function becomes hard to maintain. Open Policy Agent serves the same purpose for multi-service architectures. Node.js and Express.js documentation cover the middleware pattern in detail. - Source: dev.to / 4 months ago
Many REST frameworks also ship with limited security controls enabled by default. Express.js , a minimal web framework, does not include rate limiting or input validation out of the box and relies on middleware for these concerns. Django REST Framework includes throttling features, but they are not enabled by default. - Source: dev.to / 4 months ago
Nearly every server-side web framework uses some version of MVC. Django calls it MTV (Model-Template-View), Rails follows classic MVC, and Express.js gives you the building blocks to implement your own version. - Source: dev.to / 4 months ago
