Summary
A Show HN post on Hacker News introduces OmniDiff, an open-source Git difftool written in Rust that the author says can compare code in 25 languages as well as config files, images, PDFs, archives, cursors and fonts. The author says it can diff C++ files of tens of thousands of lines in under 100ms on a 2023 ThinkPad T14s. The tool is licensed under AGPLv3. The author says the design is based on analysis of diffs from 7400 open source repositories, though the snippet is cut off before describing that work in full.

What happened
I have been researching what the ultimate diff tool would look like, based on actual diffs in open source repositories. OmniDiff can diff: code (25 languages), config, images, PDFs, archives, cursors, fonts... It's fast. It can diff C++ files of tens of thousands of lines in under 100ms, on a 2023 ThinkPad T14s....
Why it matters
Developers who review changes in mixed repositories could get one tool for code and non-code files instead of several. Teams considering it should check the performance claims on their own repositories and review the AGPLv3 license terms before adopting it. Watch for independent benchmarks and adoption feedback from the project.
