DevReflex - Developer Toolbox

DevReflex: Developer Toolbox The developer tools you reach for all day, one keystroke away, on any page. DevReflex puts a full set of everyday dev utilities behind a single shortcut (Alt+Shift+D). Press it on any website and a sleek, full-screen toolbox glides open right over the page. Generate an ID, format some JSON, diff two blocks of text, decode a JWT, check a color's contrast, encrypt a string, then dismiss it and you're back where you were. No new tab, no context switch, no hunting for that one sketchy online tool you bookmarked years ago. Why install it • Always there: works on top of whatever page you're on, so you never break your flow. • Fast: opens instantly with a keyboard shortcut and a smooth, native-feeling animation. Press Ctrl/Cmd+K to jump to any tool or run a quick action. • 100% private: everything runs locally in your browser. No data ever leaves your device, no accounts, no tracking. • Minimal permissions: the only thing DevReflex stores is your theme preference. • Beautiful: a glassy "Deep Ocean" UI with full light and dark modes that follow your system.
