Fun fact: for simple text diffs, difftastic is now constrained by terminal output performance! I halved instruction counts for diffing a 300KLOC text file against "" and I only went from 8.2 seconds to 6.5 seconds.

I'm flattered that SemanticDiff has a blog post comparing it with difftastic! https://semanticdiff.com/blog/semanticdiff-vs-difftastic/ It's a pretty even-handed post, and it touches on some of the different design decisions. For example, SemanticDiff considers 0xA and 10 to be the same when diffing.
