DevToys

DevToys is a collection of lightweight utilities that streamline everyday development workflows. It bundles a variety of tools for converting data formats, encoding and decoding strings, formatting code, generating hashes or passwords, and performing text analysis. Additional features include graphics helpers such as color‑blindness simulation and image compression, as well as testers for JSONPath, regular expressions, and XML.

The application detects the type of data on the clipboard and automatically suggests the most appropriate tool, reducing the need to visit multiple external sites. It ships with thirty default tools and supports extensions, allowing users to add or create custom functionality.

Targeted at developers who need quick, reliable helpers for repetitive tasks, DevToys runs on macOS and is released under a stable, open‑source license. The project welcomes contributions and provides documentation for building additional extensions.
