KDiff3 overview

KDiff3 is a file and folder diff and merge tool which:

Features:
  • Compares and merges two or three text input files or folders,
  • Shows the differences line by line and character by character(!),
  • Provides an automatic merge-facility,
  • Has an editor for comfortable solving of merge-conflicts,
  • Provides network transparency via KIO,

  • Supports Unicode, UTF-8 and other file encodings,
  • Prints differences,
  • Supports version control keyword and history merging.

What’s new in version 1.11.1

  • Fix handling of KIO jobs for non-file urls: (A) Actually wait for secondary event loop to end (Not sure if this is documention bug in qt or behavior bug.); (B) Don't arbitrarily kill jobs when progress dialog is hidden.
  • Fix possible invalid line given by mousedown in Overview pane. (Caught by SafeInt range checking)
  • Fix bad algorithm in getBestFirstLine. Related regression also fixed (BUG:486909)
  • Craft based builds are now Qt6/kf6.

I tried KDiff3 some time ago, so maybe they made some progress in the meantime, but it was painfully slow compared to VisualDiffer, which weighs only 3.7 MB. On the positive side, KDiff3 is free and should work in 10.9+.
