DevToys vs WinMerge
Side-by-side comparison of features, pricing, ratings, and alternatives.
DevToys is a free, open-source desktop app that bundles dozens of everyday developer utilities, such as JSON/YAML converters, Base64 and JWT decoders, hash and UUID generators, and text/JSON diff tools, into a single offline application. It automatically detects clipboard content and suggests the most relevant tool, so you rarely need to hunt through a menu. Everything runs locally rather than through third-party websites, which matters for teams handling sensitive tokens or data. DevToys is cross-platform on Windows, macOS, and Linux, offers a command-line mode for CI use, and can be extended with community-built tools distributed through NuGet.
WinMerge is a free, open-source utility that lets you compare and merge both files and directories. It presents differences in a clear, visual format with syntax highlighting and line-by-line detail. The tool integrates with Windows Explorer, supports Unicode, and can be run as a portable application, making it ideal for developers, testers, and system administrators who need to spot changes quickly.
