Hey Product Hunt! 👋 I’m excited to share Kr3 DevTools with you all today. Like many developers, I got tired of using online tools that were slow, packed with invasive ads, or worst of all—sending sensitive data like JSON payloads, JWTs, and API keys to third-party servers. So, I built a lightweight, privacy-first developer toolbox designed to be as fast and clean as possible. ⚡ What makes Kr3 DevTools different: 100% Local & Private: All processing (JSON formatting, Base64/JWT decoding, hashing, encryption, regex testing) happens strictly in your browser. Zero data leaves your machine. Instant Load Times: No bloated frameworks or tracking scripts. It opens instantly and works seamlessly offline. All-in-One: 60+ daily developer utilities—from data converters and crypto tools to timestamp calculators and QR code generators. I’d love to get your feedback! What daily developer utilities are missing that you'd like to see added next? Thanks for checking it out! 🚀
