DevSexy is a private developer toolbox with 35 utilities for everyday engineering work. It combines free online developer tools with a native macOS app, so developers can use the same kinds of utilities in the browser or in an offline desktop workflow.

The toolbox covers JSON formatting and validation, JWT debugging, Base64 conversion, regular expression testing, text diff, timestamps, and other formatting and data conversion tasks. Instead of searching for a separate website whenever a small task appears, you can keep these utilities together and move directly to the tool you need.

The macOS developer tools are designed to keep you immersed in your work. Direct Option shortcuts and a compact HUD make tool switching quick while you are working in your editor. The native app works offline and processes tool input locally. It includes a 15-day free trial and is available with a one-time lifetime license.

The free online developer tools process input locally in your browser, with no upload required. Use them for quick JSON checks, comparing text, decoding a JWT, testing a regex, or converting Base64 data. They are useful for developers who want a convenient browser toolbox and for Mac users who want a focused desktop utility alongside their editor.
