Tool comparison
010 Editor by SweetScape Software is a professional hex and text editor best known for its Binary Templates: small scripts written in a C-like language that parse a binary file into named, typed fields you can read and edit as a structured tree. This makes it powerful for reverse engineering firmware, container formats, and calibration data where offsets and record layouts repeat. It handles very large files, offers a scriptable engine for repetitive edits, file comparison, and a wide range of checksum/hash functions. ECU researchers use templates to lay maps, headers, and identifiers over a raw dump so edits become field-level rather than blind byte pokes. It runs on Windows, macOS, and Linux and is popular across the wider RE community.
Hex Editor Neo, from HHD Software, is a Windows binary editor engineered for performance on very large files, with unlimited undo/redo, fast search, and low memory overhead. It offers pattern and regular-expression searching, a structure viewer to overlay typed definitions on data, bookmarks, file comparison, and data operations such as fill, insert, and arithmetic. It can also disassemble code for several architectures in its higher editions. In ECU and firmware work it is used to open large reads, locate repeated map patterns, apply and track edits with a full history, and diff modified files against originals. Its combination of speed and structure awareness suits tuners and reverse engineers who work with sizeable memory images.
010 Editor (Hex Editor / Reverse Engineering, SweetScape Software) and Hex Editor Neo (Hex Editor / Reverse Engineering, HHD Software) compete in the same space, so the choice comes down to coverage, workflow and price for your specific ECUs.
