About PwnDeck
PwnDeck is a growing collection of free, browser-based security and developer tools designed for professionals and enthusiasts alike.
Who We Are
PwnDeck was built by a cybersecurity professional (OSCP certified) and full-stack developer based in Spain. With years of experience in penetration testing and web development, the goal was simple: build the tools we wished existed.
What We Offer
We provide 60+ free security and developer tools, including hash generators, encoders and decoders, JWT analyzers, security headers checkers, SSL analyzers, DNS lookup utilities, password generators, and much more. Every tool is designed to be fast, reliable, and easy to use.
Why PwnDeck
Most online security tools are bloated, require signups, or send your data to servers. PwnDeck runs everything in your browser — your data never leaves your device. No accounts, no tracking, no data collection. Just tools that work.
Our Mission
Making security tools accessible to everyone. Whether you are a seasoned penetration tester, a developer looking to debug an encoding issue, or a student learning about cryptography, PwnDeck provides the right tools with zero friction.
Privacy-First Approach
The vast majority of our tools are 100% client-side. This means your data is processed entirely in your browser and never transmitted to any server. The few tools that require server-side requests (Headers Checker, SSL Analyzer, DNS Lookup) do not log, store, or retain any input data or results.
Technology
PwnDeck is built with Next.js and deployed on Vercel, ensuring fast load times and global availability. The codebase is optimized for performance, accessibility, and search engine visibility.
