I build tools that solve problems I encounter in my security work. Everything here is free and privacy-focused.
Tech & Sec Tools
A collection of free, browser-based security utilities that respect your privacy. No accounts, no tracking, no data collection.
Available Tools
JWT Toolkit
- Decode tokens to inspect headers, payloads, and signatures
- Verify signatures using HS256, RS256, and other algorithms
- Learn mode that explains what each part of the token means
- Everything runs client-side, your tokens never leave your browser
Security Headers Analyzer
- Analyze HTTP security headers for any URL
- Identify missing or misconfigured headers
- Get explanations of what each header does and why it matters
- Useful for quick recon or explaining security headers to developers
Why I Built This
When you paste a JWT into an online decoder, you’re potentially sending session tokens, user IDs, and claims to a third party. When you run headers through an analyzer, you’re revealing what sites you’re testing.
I wanted tools that do the job without compromising privacy. Tech & Sec Tools processes everything in your browser. I don’t see your data. I don’t store it.
More Coming Soon
I’m always working on new tools. If there’s something you’d find useful, let me know .
