If you need to compare (and merge) an arbitrary number of files side-by-side, I recommend diffuse https://github.com/MightyCreak/diffuse

Thanks, just today I decided that the current status of Meld (https://meldmerge.org/) was untenable for me.

It used to be a fast program, with a reasonable interface.

For a long time now its interface has been "simplifed" following GNOME 3's User Interface Guidelines, and everything ended up being hidden inside a hamburger menu.

But what definitely made it untenable was not the UX, but its tendency to crash and being really slow under the slightest load.

I was considering contributing to the project, but honestly a better engineered alternative would be welcome.

Thanks for the info (and thanks Kai Willadsen for Meld).

diffuse (and meld) are great tools for diffing text files. However, this link seems to be a binary analysis tool for diffing disassembled binaries. It is a plugin for IDA Pro, one of the foremost reverse engineering tools.

So I don't think it is in the same category as diffuse.
