Zeal is a free and open-source offline documentation browser for developers. You download docsets for the languages, frameworks, and libraries you use, and Zeal lets you search across all of them at once and jump straight to the symbol, class, or function you need. Because everything is stored locally, lookups are instant and work with no internet connection, which makes Zeal useful on flights, on locked-down networks, or any time you want to stay focused without a browser full of tabs.

Zeal is a native desktop application rather than a web wrapper, so it launches quickly and stays light on resources. It requires no account and includes no built-in tracking, and it runs on both Linux and Windows. Docsets cover hundreds of technologies and can be added or updated from within the app.

Questions & Answers

As answered by people managing Zeal and Figstack.

Who are some of the biggest customers of your product?

Zeal's answer

  • Zeal is free software with no accounts, so we do not know or track who uses it. It is used by individual developers and teams worldwide.

Which are the primary technologies used for building your product?

Zeal's answer

C++ and Qt 6, with Qt WebEngine (Chromium) rendering the documentation pages. SQLite powers the search index, libarchive handles docset extraction, and the build uses CMake and Ninja.

What's the story behind your product?

Zeal's answer

Zeal started in 2013 as a free, open-source way to get Dash-style offline documentation on Linux, where Dash (macOS-only) was not available. It adopted the same docset format, grew Windows support, and has been developed in the open ever since, maintained by a small team in their spare time with contributions from the community.

How would you describe the primary audience of your product?

Zeal's answer

Software developers who look up reference documentation many times a day: languages, frameworks, libraries, and tools. More broadly, anyone who wants a personal reference library that works without internet access. The docset catalog is developer-focused today and gradually broadening.

Why should a person choose your product over its competitors?

Zeal's answer

Compared to Dash, Zeal is free, open-source, and runs on Linux and Windows rather than macOS.

Compared to web-based tools like DevDocs, Zeal is a native desktop application that works with no connection at all, supports a much larger docset catalog, and can be summoned from anywhere with a global shortcut. Compared to searching the web, lookups are instant, ad-free, and exactly scoped to the libraries you actually use.

What makes your product unique?

Zeal's answer

Zeal combines things that usually come as trade-offs: it is fully offline, native, and free.

All documentation is stored locally and searched with instant fuzzy matching across every docset you have installed at once. It uses the same docset format as Dash, so the catalog covers every major language, framework, and tool, while running on Linux and Windows as open-source software under GPL-3.0-or-later.

  • Local-First Documentation: What It Is and Why Your AI Agent Needs It
    This isn't a new idea for developer tools. DevDocs, Zeal, and Dash have offered offline documentation browsing for years. What's new is applying this architecture to AI agents โ€” giving your coding assistant the same offline, instant, version-accurate access to docs that you'd want for yourself. - Source: dev.to / 5 months ago

  • Self-Host and Tech Independence: The Joy of Building Your Own
    I find that self hosting "devdocs" [1] and having zeal (on linux) [2] solve a lot of these problems with the offline docs. [1] https://github.com/freeCodeCamp/devdocs. - Source: Hacker News / about 1 year ago
  • Patterns for Personal Web Sites (2003)
    Yeah, I keep thinking that CHM was the peak format for offline docs. Today we have Kiwix [0] and Dash/Zeal [1] โ€“ both amazing projects, but somehow they feel more complex, and the formats they use arenโ€™t as ubiquitous.
