About

010 Editor is a commercial and proprietary text and hex editor developed in the United States, available for Windows, Mac, and Linux. It is a professional tool designed to edit any file, drive, or process, including text files, binary files, hard drives, processes, tagged data (e.g., XML, HTML), source code (e.g., C++, PHP, JavaScript), shell scripts, and log files. Its core innovation is the Binary Templates technology, which allows binary files to be parsed into understandable data structures, enabling advanced features such as disk editing, file comparison, checksum calculation, memory editing, and robust binary analysis. Praised by users as the best hex editor, it is considered superior to competitors like UltraEdit and HxD, notably for its unique ability to Undo/Redo after saving files. While it operates on a paid, proprietary license with an annual updates/support subscription and no free/lite option, it offers offline functionality and continuous development driven by user suggestions.
