Zeal brings offline documentation to Windows and Linux desktops. DocNative brings the same capability to mobile—iOS and Android apps for documentation on the go.
Zeal is an open-source offline documentation browser for Windows and Linux. It is compatible with Dash docsets, making it a free alternative for developers who do not use macOS.
The Zeal community values open-source software and cross-platform availability. The tool is well-maintained and has a loyal user base among desktop Linux developers.
The gap is mobile. Zeal focuses on desktop platforms. DocNative fills the mobile space with native iOS and Android apps using the same offline-first philosophy.
