DevSexy

Native developer tools, one shortcut away

DevSexy is an offline macOS developer toolbox with 35 tools, including a JSON formatter and validator, JWT debugger, Base64 converter, regex tester and text diff. Tool input is processed locally. Global Option shortcuts open focused tool popups from your editor; hold Option to see the shortcut learning HUD. Smart from Clipboard helps choose a matching tool when explicitly invoked.

Built for the Mac

Built with Swift 6, SwiftUI and AppKit: a real menu bar, native windows and text editing, clipboard operations and local file open/export. Ships as a Universal 2 app for Apple Silicon and Intel. Requires macOS 15.4 or later. Fixed bundled JavaScript processors run through JavaScriptCore; the interface is native.

Trial and one-time licenses

The Mac app has a 15-day full trial. Personal starts at US$29.99 once for 5 Macs, with lifetime use of the purchased current version. There is no subscription. Future major upgrades are not promised free. After the trial, JSON, Base64, Unix Time, URL Inspector and Text Diff remain available.
