Synalyze It!
What Synalyze It! is
Synalyze It! is a macOS tool for examining binary files. It parses structures, strings, and numbers and displays them beside a hex editor, supporting software developers, data stream experts, and computer forensics practitioners. An interactive grammar editor lets users create and modify XML grammars for automatic decoding, and free grammars are available for formats including PNG, JPEG, WAV, and QuickTime. The editor handles files of unlimited size by accessing only the visible portion rather than keeping the whole file in memory. Search covers text, numbers, and masks, while analysis panels provide checksum, histogram, and code page comparison tools. Binary comparison includes an intelligent diff for insertions and deletions and byte-by-byte comparison for equal-size files. Pro adds scripting with sample scripts. A free hex editor is available, and advanced features can be tried without limitation for two weeks. Pro costs $44.99 per user for academic/private use or $99.99 per user for commercial use.
