Synalyze It! vs iBored

You can even add your own grammar for a new file type structure. Great for analysing foreign file formats.

Compares binary files byte-by-byte or with a more flexible algorithm that shows inserts and deletions in any of the compared files.

Huge files can be opened and edited instantly because only the displayed part is loaded to memory.

The script engines allow you to automate repetitive tasks and extend the standard functionality.

Selecting a bit of source code and using th e"Show Checksums" feature allows seeing different checksums for selected text and get it updated in real time.

The editor allows selecting a bit of source code and highlight it.

The histogram shows the distribution of all byte values in the file. This lets you quickly see if a file is compressed or encrypted.

This feature lets you compare the text representation of a byte sequence for numerous text encodings. This is the most efficient way to find the correct text encoding, be it ASCII-based, EBCDIC or any other code page supported by libICU.

The search results are immediately highlighted in the hex editor. Text, numbers, and masks can be searched.

iBored doesn't cost anything.

Uses an extensible templates system to view structures of common disk and volume formats.

iBored is one of the few disk editors on the Mac.

Can be used to remotely assist in viewing and repairing disks over the internet: iBored has to be started on both computers, and then one can connect to the other and view and modify its data (after getting permissions from the target side).
