DevToys

DevToys is a desktop application that provides developers with a collection of more than 30 practical utilities for everyday coding tasks. It handles common operations like JSON/YAML conversion, Base64 encoding/decoding, JWT token inspection, text comparison, hash generation, and many other formatting and conversion needs. Everything works offline, keeping your data private and accessible without internet connection.

The application stands out with its Smart Detection feature that automatically identifies the most suitable tool based on your clipboard content. It offers a clean, modern interface with system integration features like compact overlay mode, search functionality, and theme support. Built as open-source software, DevToys is extensible—you can add community-created tools or build your own using their SDK.

This tool is most valuable for developers who frequently work with data transformation, need to validate code formats, or require quick access to utilities without relying on online services. Typical use cases include preparing API payloads, debugging data formats, generating test credentials, or formatting configuration files during development workflows.
