Overview

Meld combines file diffs, folder comparisons, and version-control workflows in one application. Live updates and change navigation help keep edits in view, while folder comparisons surface missing or modified files. That breadth is useful when reviewing a project rather than a single isolated file; the absence of binary comparison makes its scope firmly text-focused.

Key features

Compare and merge

Meld can compare, edit, and merge files, with three-way assistance that displays the base version and provides conflict-handling tools. That extra context is valuable when reconciling competing edits, not merely inspecting differences. Folder comparisons identify missing and modified items and let users ignore selected files or folders, helping focus a review on relevant changes.

Filters and version control

Regular-expression filters can suppress matching text in file comparisons, which can help when recurring lines distract from meaningful edits. Filtering is incomplete, however, and cannot change the number of lines, so it is not a flexible way to reshape a comparison. Meld supports Git, Mercurial, Bazaar, and Subversion, including integration with tools such as git mergetool; that makes it a natural fit for developers who want comparison and merge work alongside established version-control workflows.

Pricing

Meld is free: its plan costs 0.00 USD per free and is licensed under GPLv2 or later, except as noted. There is no paid tier or trial to weigh against the core features, so it is an accessible option for individuals and teams willing to use open-source software. The free price does not extend its platform or comparison scope: binary files remain outside its capabilities.

Platforms

Meld supports Linux and Windows. Linux users can obtain it through most Linux and Unix distributions or Flathub. Windows users can download an installer, but the lack of automatic updates and portable installs makes it less convenient for users who expect those deployment options.

macOS is not supported, despite semi-official builds and installation options through Homebrew, MacPorts, or Fink. Teams that require a supported macOS application should choose another tool rather than rely on those options. The project lists version 3.24.0 as its stable release, dated 20 June 2026.

Who it's for

Meld is best suited to developers and teams reviewing code changes, understanding patches, or resolving conflicts across files and version-controlled projects. Its file, folder, and three-way merge tools make it more useful for those workflows than a basic two-file viewer. It is a poor fit for binary comparison, supported macOS use, or Windows deployments that require automatic updates or portable installs.

Pros and cons

Pro: Three-way merge assistance displays the base version and includes conflict tools, giving conflict resolution more context.
Pro: Support for Git, Mercurial, Bazaar, and Subversion lets developers bring Meld into several established version-control workflows.
Pro: File and folder comparison, editing, and merging are available free under GPLv2 or later, except as noted.
Con: Binary comparison is not supported, limiting Meld to workflows it can handle through its file comparison features.
Con: macOS is not supported, and Windows lacks automatic updates and portable installs.
Con: Text filters are incomplete and cannot change line counts, which constrains their usefulness for more complex comparisons.

Alternatives

For other comparison tools, see File Comparison Software and Diff and Merge Tools. Pick WinMerge instead if you need a free, open-source file and folder comparison and merge tool specifically for Windows. Code Compare is another option with a free version and a paid Pro offering. Consider Diffchecker if its Linux, macOS, web, and Windows platform coverage suits your setup; its free Basic plan limits some features by monthly try counts, while Pro + Desktop costs 15.00 USD per month.

Buddi, Diffract, cwdiff, NextDiff, and SmartSynchronize are also listed as alternatives.

Verdict

Choose Meld if you need a free, version-control-aware tool for comparing files and folders and working through three-way merges on Linux or Windows. Its combination of conflict assistance and support for four version-control systems is the core reason to pick it. Look elsewhere if binary comparison, supported macOS use, or Windows auto-updates and portable installs are requirements.
