  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, encrypt a string, pick a color, 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.
    • 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.

    • UUID, NanoID & ULID
    • Epoch / Unix timestamp converter

  DevReflex: Developer Toolbox

  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.
