Meld
Open-source, Python-based visual diff and merge tool for comparing files and folders.
What is Meld?
Meld is a visual diff and merge tool. You can compare two or three files and edit them in place (diffs update dynamically). You can compare two or three folders and launch file comparisons. You can browse and view a working copy from popular version control systems such such as CVS, Subversion, Bazaar-ng and Mercurial. Written with Python and GTK.
Requirements: Python 2.6 GTK+/pygtk 2.14 GLib/pygobject 2.16 GtkSourceView/pygtksourceview 2.10 (optional)
Note: There are ports to Mac but the app doesn't "officially" run on Mac.

Similar to the program Diffinity, but on an average seems to lack the refinement. Unlike Diffinity, I have an immediate urge to change settings.. The text shows big. The colors a bit louder. Very direct messages that must be clicked away.. such as when 2 files are identical. No Context Menu choice. It does have an advantage.. it will wrap words.
Visually pretty ok. Functionality superb. Folder, files, merging - works like a charm. You MUST enter the preferences and turn on the features other tools have enabled by default. The color themes are not as good. is able to view git changes (can you commit and pull?) and can create patches.
Would love to see a more windows native theme - and a better color theme with more color styles (syntax is not colored with enough differences).
Diff bars are on the outside --- love to see them in the middle :)
Easy on the eyes User Interface (UI) which is clear and to the point. Should have used it sooner!
The interface is more basic compared to Beyond Compare and it's not possible to paste the path to compare files and folders
Sadly Meld in 2023 still does not have an official MacOS build and the fact that the unsupported build are not signed makes it impractical to use. With free Github Actions, the developers cannot claim that they don't have access for a mac for CI/CD purposes.

Every other year I retry Meld, hoping that the most popular open-source file merge tool would catch up. Still, even in 2022, that seems to be hopeless as they lost me after "brew install meld", when trying to run meld, prompted me about the unrecognized developer certificate. I am a software engineer, so I will not break security of my system to try running meld.
Crossplatform, Free, Opensource, Highlight line difference.
