HOP

The application provides a desktop environment for opening and modifying documents in the HWP and HWPX formats. It supports the full edit of these proprietary Korean word‑processing files, allowing users to view content, edit text, and save changes within a native interface. Compatibility spans the major desktop operating systems, including macOS, Windows, and Linux, with installation options such as downloadable installers, Homebrew packages for macOS, and Debian/Ubuntu or Fedora packages for Linux. The software is built on the rhwp engine, an open‑source implementation that handles the underlying HWP file structure, and is released under a stable, open‑source license. It is intended for individuals or organizations that need to work with HWP documents without relying on proprietary software, offering a cross‑platform solution for document creation and revision.
