010 Editor vs Bless

010 Editor is a text and hex editor for working with text files and binary data on Windows, macOS, and Linux. Its Binary Templates represent files as hierarchical data structures, with variables connected to bytes that can be edited. The maker says templates can parse and edit more than 300 formats, including ZIP, BMP, and WAV. The text editor handles files larger than 50 GB and includes syntax highlighting, column mode, and unlimited undo. Tree-sitter provides real-time parsing for more than 45 syntaxes, including C/C++, Python, Rust, JavaScript, and JSON. Analysis tools include binary comparison, search and replace, data visualization, checksums and hashes, a histogram, and disassembly. C-like scripts can automate edits, run from the command line without a user interface, and use an integrated debugger. An online repository lets users download, install, and submit templates and scripts. The maker describes uses in digital forensics, malware analysis, memory and process analysis, and data recovery. Process editing is available only on Windows. A free 30-day trial and 60-day money-back guarantee are offered. New-user perpetual licenses cost $59.95 as a one-time purchase for home or academic use and $149.95, paid once for commercial use; each is for one user and includes one year of free support and upgrades.

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.
