I am contributor to helix that is working on bringing diff functionality to helix. You can check the current progress on the first related PR on github (https://github.com/helix-editor/helix/pull/3890 https://github.com/helix-editor/helix/pull/3890). The PR is pretty far along. A new gitoxide release is happening today and once that is out we will only be waiting for an upstream library to merge my fixes. The machinery developed in that PR contains most of the heavy lifting for implementing a vimdiff tool. The only thing that is missing is support in the rendering system to display them. I will be collaborating with one of the maintainers to make that happen as well so we will get a diff mode in helix sooner rather then later.
