About DevToys
DevToys is a desktop app that bundles everyday developer utilities in one place. Its default tools work offline, so you can handle common data tasks without sending them to third-party websites.
What it does
The app includes converters, formatters, encoders and testers for common tasks. When you copy something to the clipboard, it can suggest the tool that fits the content. A compact overlay mode keeps tools on top of other windows while you work.
Key features
- 30 default tools that work offline
- JSON to YAML and YAML to JSON conversion
- JWT encoder, hash generator and text comparer
- Clipboard detection suggests a matching tool
- Command line version for scripts and pipelines
- Extensible with community tools
Who it's for
Developers and testers who switch between formats many times a day, such as JSON, Base64 and regular expressions. It is a good fit for people who want utilities without opening many websites.
Pricing and good to know
DevToys is free and open source under the MIT license. It runs on Windows, macOS and Linux. The command line version is a separate app, and it can be used in continuous integration jobs. Smart detection behaviour can be changed in the app settings if it feels too eager.
