DevToys vs Meld
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.
Meld is a free, open-source visual diff and merge tool that compares two or three files side by side, highlighting changed lines and letting users merge differences with a click. It also compares entire folders, flagging which files were added, removed, or modified, and can drill down into subfolders to review nested changes. Meld integrates with Git, Mercurial, Bazaar, and Subversion, and can be set as the diff and merge tool for 'git mergetool' or similar commands in other version-control systems. It runs on Linux natively, with official Windows installers and community-maintained macOS builds through Homebrew, MacPorts, or Fink.

- Actively maintained with a June 2026 stable release.
- Desktop-only, no hosted/web version for quick one-off use
- Tool set is general-purpose rather than deeply specialized for any one workflow

- macOS builds are community-maintained rather than officially packaged by the GNOME project.
- Interface looks utilitarian compared to some modern commercial diff tools.
- Requires installing Python and GTK dependencies on some platforms.
