KDiff3 vs Beyond Compare opinions
Most users think KDiff3 is a great alternative to Beyond Compare.
Guest
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.
