Meld is a graphical diff and merge application for inspecting changes across files, folders and version-controlled projects. Its side-by-side interface is designed to make edits, conflicts and related change blocks easier to follow without switching between separate tools.
Comparisons can involve two or three files or directories. Meld also gives repository users a visual way to inspect working-tree changes before committing and to deal with merges launched from version-control tooling.
Text filtering, syntax-aware editing and change navigation help keep attention on meaningful differences rather than surrounding noise.
This is free and open source software.
Key Features
- Compare, edit and merge files with live comparison updates.
- Navigate directly between changes and operate on individual change blocks.
- Perform two- and three-way comparisons and use merge assistance for conflicts.
- Display the base version during three-way conflict resolution.
- Compare directory trees and identify missing or modified files.
- Drill down from a folder comparison into a detailed file comparison.
- Ignore selected files, folders or text patterns when they are not relevant.
- Work with Git, Mercurial, Bazaar and Subversion repositories.
- Inspect version-control states and perform common actions including commit and push.
- Integrate with external workflows such as
git mergetool. - Offers internationalisation support.
