Zeal is an offline documentation browser inspired by Dash, designed for developers to access technical documentation without an internet connection. It supports Windows and Linux, offering a user-friendly interface to download and manage docsets for various programming languages and frameworks. Users can search and filter docsets using specific syntax, and queries can also be initiated via the command line. Zeal allows customization by enabling users to create their own docsets following Dash’s guidelines. Built with CMake, Qt, libarchive, and SQLite, it is open-source under the GPLv3 license. Support and feedback are available through GitHub, IRC, Twitter, and email.
