Hex Fiend is a fast, native Mac hex editor for inspecting and editing binary files at the byte level. It is used by developers, reverse engineers, security researchers, and anyone who needs to examine file structure, debug binary data, or patch executable files. The app displays file contents in the classic hex dump format (offset, hexadecimal bytes, and ASCII) and supports large files efficiently with a responsive, streamlined interface. It is free, open-source (available on GitHub), and has become the standard hex editor for modern macOS development.
