Difftastic seems really nice! Unfortunately it shows some changed binary files which makes it sort of unusable. `file` reports these files as "ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, stripped" and the MIME type/encoding is "application/x-sharedlib; charset=binary" so not sure why difftastic is trying to show them as thousands of changed lines of text...
