Hntui is a Terminal User Interface (TUI) for browsing Hacker News, allowing users to navigate and interact with the site from their terminal. It features a sleek and elegant design, supporting truecolor, mouse events, and UTF-8, and can be installed as a standalone binary or via Bun. The application includes keybindings, a story list, story details with comments, links popup, and context menu, and is compatible with modern terminals on macOS, Linux, and Windows. Hntui also includes an auto-update feature, which checks for the latest release and provides a quiet hint in the status bar when an update is available, allowing users to easily keep their installation up-to-date.
