Handle tasks such as JSON formatting, text comparison, and regular expression testing with DevToys, a desktop toolkit.
About DevToys
DevToys is a cross-platform desktop toolkit (with a separate CLI version) designed as a Swiss Army knife for developers handling common daily tasks. It is free, open source, and privacy-focused, available for Windows, macOS, Linux, and web, eliminating the need to upload sensitive data to untrusted third-party websites for simple data operations.
The toolkit includes 30 default offline tools for tasks such as JSON/YAML conversion, Base64 text and image encoding/decoding, JWT encoding/decoding, text comparison, hash generation, and regular expression testing. It offers smart clipboard detection to automatically match content to the appropriate tool, and integrates with host operating systems via features like picture-in-picture mode, taskbar jump lists, and dark/light theme support. DevToys is also extensible, with additional tools available through community packages or custom builds using its public SDK.
