Hey Product Hunt community! 👋 I’m the creator of DevX Tool. Like many of you, my daily coding workflow involves formatting JSON, decoding JWTs, generating UUIDs, or double-checking regex strings. But I grew incredibly tired of using clunky, ad-heavy legacy websites that look like they were built in 2005. Worse, I hated the anxiety of pasting sensitive API payloads, tokens, or configuration keys into mysterious online servers. That’s why I built DevX Tool: a clean, lightning-fast, and entirely browser-first toolbox. 🔒 Zero Server Roundtrips: Everything is processed locally in your browser using the Web Crypto API. Your data never leaves your machine. ⚡ Zero Friction: No accounts, no paywalls, and no complicated setup. Open a tool, get your result, and get back to work. 📚 Built-in Knowledge Base: To make it even more practical, I’ve paired our 11 core utilities with deep-dive engineering guides and performance benchmarks (like our recent Postgres UUID v4 vs v7 index fragmentation tests). The platform is completely free to use. I would absolutely love to hear your feedback! What other utilities, encodings, or generators should we add to the directory next? Thank you for checking it out! 🚀
