BinEd vs HexEd.it

BinEd is a free, open-source binary and hex viewer and editor written in Java. It shows data as hexadecimal codes and text, with binary, octal, and decimal modes. Editing supports Unicode and other character sets, insert or overwrite modes, text or hexadecimal search with highlighted matches, and undo and redo. The maker says the editor supports files up to exabytes; on Android, that capacity is qualified as partial file mode. BinEd runs on desktop platforms supporting Java 8 or later, and is also available as an Android APK and browser demo. The project uses Apache License 2.0, though additional addons may have different licenses. Listed integrations include NetBeans, IntelliJ, Eclipse, JDeveloper, BlueJ, jEdit, Autopsy, and Ghidra. The feature list marks byte-for-byte comparison as complete and search/replace as partial in the editor application. The maker also lists possible Java heap-space freezes after many large modifications, possible delta-mode corruption if another application changes files simultaneously, and memory leaks.

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.
