    Since I cannot access or browse external websites in real-time, I cannot provide an accurate or reliable assessment of FullStackToolkit's actual pros and cons.

Questions & Answers

As answered by people managing FullStackToolkit and Preflyt.dev.

What makes your product unique?

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.

Why should a person choose your product over its competitors?

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

How would you describe the primary audience of your product?

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

What's the story behind your product?

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.

Who are some of the biggest customers of your product?

Preflyt.dev's answer:

Preflyt is early stage with 80+ developers using it organically. Focused on indie developers and small teams right now
