Comments about KDiff3 as an Alternative to Beyond Compare
Who pays for software in 2023? Only iLuddites. This type of software is done. New “features” nowadays are merely capitalist job creation schemes. Failing attempts to justify still taking money for an abundant resource.
I would like to suggest kdiff3 as the best alternative selection for Beyond compare, esp. folder compare and sync!

Most users think KDiff3 is a great Beyond Compare alternative.
KDiff3 is the most popular Mac alternative to Beyond Compare.

As BC and unlike Meld, it align changes by adding lines, which is a key feature to visually compare code. Meld explicitly states it does not do that. kdiff3 also supports multiple platforms (as stated). Unfortunately, it does not support on-click line/block merging (merge from side to side visually) like Meld or BC.
