DevUtils features
Work entirely offline
Anything you do with DevUtils you do offline. There’s no more need to paste JSON strings or any kind of sensitive data into random websites — DevUtils does it all locally on your Mac.
Popular development tools
Unix Time Converter, JSON Format/Validate, Base64 Encode/Decode, Regex Tester, UUID Generator, and more. New tools are added regularly with updates. Scripting will be added soon, so you’ll be able to add your own custom tools/scripts.
Smart detection
Once you see how much time DevUtils saves you, you’ll want to keep it at hand. Access DevUtils via the menu bar or use a global hotkey to open the app anytime. You can also right-click > Inspect in DevUtils.app. The app will automatically open the tool you need based on your clipboard content.
