Hey Product Hunt! 👋
I'm Axel, a solo developer based in Abidjan, Côte d'Ivoire. I built Dev // Cyber Toolkit because I was tired of re-googling the same regex symbols and re-opening the same five sites just to hash a string or decode a JWT.
It's a small floating widget you install once and keep on screen: symbol palettes, a quick code scratchpad, and 17 utilities (Base64, hashing, password strength, JWT decoder, CIDR calculator, cron translator, and more). There's also an optional "Mentor Mode" that adds a short plain-language explanation under each tool — useful if you're still learning what a JWT actually is.
100% free, no account, no ads, nothing locked behind a paywall. Available in French and English.
I posted it on Show HN last week and it brought in 135+ visitors from that single post — which told me the core idea (one lightweight place for the small stuff) actually resonates beyond just me. That's what pushed me to bring it here too.
Would love your feedback, especially on what's missing or confusing. Thanks for checking it out 🙏
