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.
HxD is a free hex and disk editor for Windows developed by Maël Hörz (mh-nexus). It opens files of virtually any size, plus raw disks and system RAM, and presents byte-level views with fast search, replace, export, and file comparison. In ECU tuning it is a staple for inspecting raw firmware reads, locating map or code regions by byte pattern, comparing an original dump against a modified one to confirm exactly which bytes changed, and applying manual patches. Built-in checksum and hash calculators, a data inspector, and fill/insert operations help verify edits and understand binary layout. Tuners reach for it alongside dedicated map editors whenever a change must be checked or performed by hand. It is lightweight, portable, and widely trusted in the community.
