Bless vs Hex Editor Neo

Bless is a free binary editor for editing files as sequences of bytes. It supports multilevel undo and redo, customizable data views, multiple tabs, and fast find and replace. The project highlights efficient handling of large data files and raw disk editing, with search and save operations running in multiple threads. Bless exports to text and HTML, while plugins can add other export formats and extend the editor. It is written in C# with Gtk# bindings for GTK+ and distributed under the GNU General Public License, version 2 or later. GNU/Linux is the main target; listed supported platforms are Linux and Windows, and the README says it should also run on *BSD, Solaris, and Win32. Building the current version requires GTK+, a Mono/.NET runtime and C# compiler, Gtk# bindings, pkg-config, and Meson. The GitHub releases page has no releases, and the README provides source-build instructions. NEWS lists version 0.6.3 dated 2020-10-11. Saving a changed-size file under the same name requires temporary space for both files; same-size files save in place.

Hex Editor Neo is Windows software for editing binary files, including files of any size and physical disks such as HDDs, SSDs, optical discs and USB disks. Editing tools cover typing, cutting, copying, pasting, filling, deleting, inserting, importing and exporting data. Search can match binary, hexadecimal, decimal, octal, float, double, character, ASCII and Unicode patterns, including wildcards; replacement supports arbitrary-length patterns and regular expressions. The editor provides unlimited undo and redo, with operation history that can be saved or loaded. It creates 32-bit and 64-bit binary patches, as well as self-installing executable patches with file-hash checking. Portable installation avoids registry changes, shell extensions and shortcuts. More than 130 text encodings are supported, including UTF-8 and UTF-16. Settings can be stored in the registry, local files or shared locations such as OneDrive and Dropbox. The Free Hex Editor Neo plan costs nothing and includes basic editing features. Free Edition users receive limited or no support; email and phone technical support is provided to registered users of Standard, Professional and Ultimate editions.
