Meld is a visual diff and merge tool, targeted at developers. It allows users to compare two or three files or directories visually, color-coding the different lines.

Meld can be used for comparing files, directories, and version controlled repositories. It provides two- and three-way comparison of both files and directories, and supports many version control systems including Git, Mercurial, Baazar, CVS and Subversion.

Meld is free and open-source software subject to the terms of the GNU General Public License (GPL-2.0-or-later).


Requirements for Meld 3.18.0 are as follows:
