Hex Fiend
by ridiculous_fish

A fast and clever open source hex editor
for Mac OS X.
  • Insert, delete, rearrange.  Hex Fiend does not limit you to in-place changes like some hex editors.
  • Work with huge files.  Hex Fiend can handle as big a file as you’re able to create.  It’s been tested on files as large as 118 GB.
  • Small footprint.  Hex Fiend does not keep your files in memory.  You won’t dread launching or working with Hex Fiend even on low-RAM machines.
  • Fast.  Open a huge file, scroll around, copy and paste, all instantly.  Find what you’re looking for with fast searching.
  • Binary diff.  Hex Fiend can show the differences between files, taking into account insertions or deletions.
  • Smart saving.  Hex Fiend knows not to waste time overwriting the parts of your files that haven’t changed, and never needs temporary disk space.
  • Data inspector.  Interpret data as integer or floating point, signed or unsigned, big or little endian...
  • Embeddable!  It’s really easy to incorporate Hex Fiend’s hex or data views into your app.  Its permissive BSD-style license won’t burden you.
