010 Editor vs HexEd.it

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.

HexEd.it is a browser-based editor for inspecting and changing binary files and hexadecimal data. Processing takes place in the browser, and the site says it does not send file data to its server. Once the app has been downloaded during a first visit, it can also work offline. Analysis and editing tools include viewing data in multiple numeric formats, bit-wise changes, search and replace, bookmarks, and multiple selections. HexEd.it can decode and encode Motorola S-Record and Intel HEX files, and identify more than 20,000 file types. Its hash lookup can query Google, VirusTotal, MetaDefender Cloud, BitBaan MALab, and Hybrid Analysis without uploading the file. The feature page says it can process files up to several terabytes; the manual reports testing on files up to 150 GiB. The site lists HTTPS, a restrictive Content Security Policy, Feature Policy, and Subresource Integrity as security measures. It is free for commercial and non-commercial use, but the maker says it is not open-source.
