About regex.quest

Modern. Privacy-focused. Fast.

Privacy First

Your data never leaves your browser. We use Web Workers to process all regex patterns locally on your device. No server logs, no tracking, no leaks.

High Performance

Powered by Vite and React, regex.quest is optimized for speed. Complex pattern matching happens off the main thread, ensuring the UI never freezes.

Works Offline

Installed as a PWA (Progressive Web App), this tool works perfectly without an internet connection.

Developer Focused

Designed with a clean, dark-mode-first aesthetic that helps you focus on the pattern, not the UI clutter.

Built with TypeScript, React, and Tailwind CSS.
