The best at hex
Described in one word, indispensable. Synalyze it is much more than a hex editor. It’s like a logic logic analyzer for binary files. I would like for it to be able to compare and difference two files similar to Kaleidoscope, but for binary files, to see changes between two saved files, but missing that feature isn’t worth taking a star away, because it does more than any other hex editor I’ve ever used, and it does it all very well. It’s worth the extra cost for the pro version, I found very quickly that the scripting support is very much necessary.
