Most bookmarked dev-tool sites get slower and more ad-heavy over time, or start gating basic features behind a signup. Quietbench is a small suite of the utilities I reach for most often - JSON formatter, regex tester, cron builder, WCAG contrast checker, and API request tester - built to stay fast, free, and signup-free.
Everything runs entirely client-side in your browser. No accounts, no data sent to a server, no ads. Built with React, Vite, and TypeScript, deployed on Cloudflare Pages.
