Swiss Army knife for developers

Open source and cross-platform

DevToys is free, open source and is privacy-focused on Windows, macOS and Linux! No need to use many untruthful websites to do simple tasks with your data.

It comes with a set of 30 default offline tools, including:

• Json to Yaml and Yaml to Json converter
• Base64 Text & Image converter
• JWT encoder and decoder
• Text comparer
• Hash generator

DevToys is extensible. More tools are available through the DevToys community, and you can build your own!

Go faster with Smart Detection

DevToys can automatically detect the best tool that fits the clipboard content.

A lightbulb icon indicates the tool(s) that can be used with the clipboard content. If only one tool is detected, the clipboard content will be automatically pasted in that tool*.

*Smart detection behavior can be customized in the app settings.

Integration with the system

DevToys is made with and designed to embrace its operating system.

• Compact Overlay aka. Picture-in-Picture mode
• Task Bar's jump list
• Search bar
• Rich code editor
• Multiple instances
• Dark / Light theme
• Modern and responsive UI
• Extensible (see our SDK and documentation)

Made with by Etienne Baudoux and Benjamin Titeux, from Seattle, WA and Paris, France.

Use it from the Terminal

DevToys can used from a command line prompt, making it possible to use in new scenarios such as Continuous Integration.

Most tools that make sense to be used as command prompt are available in DevToys CLI. DevToys CLI is a separate app from the one with a GUI. Both are extensible.
