Hex Fiend is a fast, open-source hex editor for macOS that supports inserting, deleting, and rearranging bytes in files of virtually any size without loading them into memory. It also offers binary diffing, a data inspector, scriptable binary templates, and an embeddable framework for adding hex views to other apps.

Use cases

• edit binary files on macOS
• inspect raw bytes of a large file
• compare two binary files for differences
• interpret bytes as integers or floats with different endianness
• visualize binary file structure with templates
• embed a hex editor view in my own macOS app
• open a 100 GB file without running out of RAM

When to choose

• you need a fast hex editor on macOS that handles huge files
• you want binary diffing that accounts for insertions and deletions
• you need an embeddable hex/data view framework with a permissive BSD license
• you work on low-RAM machines and need a small-footprint editor

When to avoid

• you need a hex editor on Windows or Linux
• you need a cross-platform or terminal-based hex editor
• you need disk forensics or advanced reverse-engineering suites beyond hex editing
