DevSexy brings 35 private developer utilities to your daily workflow: JSON formatting and validation, JWT debugging, Base64 conversion, regex testing, text diff, and more.

Use the free online developer tools with browser-local processing, or stay immersed in the native macOS toolbox. The Mac app works offline and uses direct Option shortcuts and a compact HUD to switch tools without breaking your flow.

Web tools are free. DevSexy for Mac offers a 15-day trial and a one-time lifetime license. Your tool input stays local, with no upload required.
