DevToys—an open-source Swiss army knife for developers


DevToys is like a Swiss Army knife for software and web developers to help with everyday development tasks such as comparing and converting text and images, testing RegEx, formatting JSON and XML data, compressing images, etc.

It is available for free for Windows from the Microsoft Store.

I wish I’d had this years ago.
