DevToys is a desktop application that bundles dozens of small utilities for common developer tasks like encoding, formatting, converting, and generating data.
The tool addresses the friction of switching between multiple websites and applications to handle quick development chores. It provides thirty built-in tools covering converters (JSON to YAML, date and number base conversions), encoders and decoders (Base64, JWT, QR codes, HTML entities), formatters (JSON, SQL, XML), generators (hashes, passwords, Lorem Ipsum), graphics utilities (color blindness simulation, image compression), and text tools (regex testing, markdown preview, text comparison). A Smart Detection feature automatically suggests the most relevant tool based on clipboard contents, reducing the need to manually navigate to the right utility.
DevToys runs as a native cross-platform desktop application on Windows, macOS, and Linux, built with C# and Blazor. The tool is designed to be extensible, allowing developers to create and distribute custom tools through an extension system. Anyone handling repetitive data transformation tasks—encoding credentials, testing regular expressions, formatting configuration files, or converting between formats—will find value in having these utilities available locally without relying on web services. The application emphasizes privacy by keeping all operations local rather than sending data to external websites.
The project maintains active development with regular contributions across multiple areas. Code contributions span a broad range of improvements and new features. The design work involves dedicated designers working on the visual presentation and user experience. Platform-specific development includes dedicated effort on the macOS implementation to ensure quality across all supported operating systems.
