About Meld
Meld is a visual diff and merge tool for comparing files and folders. It works with many version control systems and helps you review changes and resolve merges in a clear side-by-side view.
What it does
Meld compares two or three files, or whole directories, and highlights the differences. You can edit files while you compare, move between change blocks and filter out irrelevant differences. For three-way merges it shows the base version and helps you handle conflicts. It also helps when you are reviewing patches.
Key features
- Two-way and three-way comparison
- Folder comparison
- Live editing while comparing
- Text filters for ignoring differences
- Conflict handling in three-way merges
Who it's for
Meld suits developers who review changes or resolve merge conflicts, and anyone who needs to compare two versions of a project. It is packaged for most Linux and Unix distributions.
Pricing and good to know
The project is open source and free to use. It has a Windows installer, and the site notes that macOS is not yet supported, though semi-official builds exist. Meld does not yet support automatic updates or portable installs.
