OFFLINE-FIRST LEARNING WORKSPACE
Learn with your documentation.
ZealRN brings offline docs, page-linked notes, code experiments, and local developer tools into one focused workspace.
0.1.0 downloads coming soon.
THE WORKFLOW
Read. Capture. Practice. Review.
Start with a docset page, keep the important idea beside it, then test what you learned without leaving the app.
Take notes
Keep a scratchpad or a note attached to the current page.
Try examples
Use the Web Playground to explore HTML, CSS, and JavaScript.
DESKTOP
A study desk for serious documentation work.
ZealRN Desktop supports the full downloadable docset catalog, local SQLite notes, searchable exports, and developer tools.
- Start Note and page-linked Learning Notes
- Markdown preview, PDF, JSON, and ZIP exports
- Embedded Linux terminal with POSIX PTY
- Windows opens external PowerShell, cmd, Windows Terminal, or Git Bash
WEB TRIAL
Try the learning loop in your browser.
ZealRN Web is an installable PWA with starter guides, browser-local notes, and an HTML/CSS/JavaScript playground. It works offline after the first visit.
Your study data stays close.
There are no accounts, analytics, or note uploads. Desktop stores notes in SQLite; Web stores them in IndexedDB. Export backups before clearing application or browser data.
Offline by design
Documentation and notes remain useful without a network connection.
Honest boundaries
Web has no terminal access. Windows uses external terminals. Playground isolation is defense-in-depth, not a perfect sandbox.
Open source
ZealRN is independently maintained and based on Zeal under GPL-3.0-or-later.
One product, two entry points.
What is the difference between Desktop and Web?
Desktop supports downloadable docsets, native storage, exports, and developer tools. Web is a small, installable browser trial with starter documentation.
Can I use the terminal in the browser?
No. The Developer Terminal is a desktop feature. Linux embeds a normal user shell; Windows opens the user's external terminal tools.
Is ZealRN affiliated with Zeal?
ZealRN is based on Zeal but independently maintained and not officially endorsed by the upstream project.
