Where Twofold is better

  • ✓It's a real Mac app. Built with AppKit and Core Text: native scrolling, keyboard shortcuts, light and dark themes that follow the system.
  • ✓It's free and open source. No license to buy per machine, no key to keep track of.
  • ✓It's easy on the eyes. The Fluid layout joins changes with curves through the middle instead of padding both sides with blank lines.
  • ✓It's small. One job, done quickly: 100,000 lines in under 60 ms, 10,000 files per side in about a second.

Where Beyond Compare is better

  • –Breadth. Beyond Compare also syncs folders, compares over FTP and SFTP, and handles tables, hex, images and archives. Twofold does none of that.
  • –Merging. Beyond Compare merges, including three-way in the Pro edition. Twofold v1 only shows differences.
  • –Other platforms. If your team shares one tool across Windows, Linux and Mac, Beyond Compare runs everywhere. Twofold is Mac only.

Should you switch?

If you use Beyond Compare mainly to look at changed text files and folders on your Mac, Twofold does that with a native interface and no license. If you rely on folder sync, remote comparisons or merging, Beyond Compare is still the better tool.
