Hey Product Hunt community! 👋 I'm Muhammad Umair, creator of DevOmniTools. Like many engineers, I found myself repeatedly pasting confidential authentication tokens (JWTs), SQL queries, and JSON payloads into random online formatter tools — wondering where that data actually goes. We built DevOmniTools to eliminate this privacy dilemma. Everything runs 100% locally in your browser memory via Web Crypto API and Web Worker sandboxes. Zero network data transmission, zero server logs, 0 CLS, and full RTL multilingual support (EN, ES, DE, AR). We now have 136+ production utilities ready. I’d love your feedback and feature requests!
