Kiwix is a free open source app for offline viewing and searching of Wikipedia, Gutenberg, StackExchange etc. It lets you use and distribute physical copies of websites entirely offline.
You can follow at:
The app is available for Linux, Mac, Windows, Android and iPhone/iPad from https://www.kiwix.org
This kind of offline website option is really important not just to people who have broken internet, but also those who live in remote areas or in difficult political situations.
Offline material can be distributed physically or through a local server and mesh network without ever connecting to the internet, which means it can bypass geographic or political barriers.
Kiwix themselves give an interesting example of this: https://www.kiwix.org/en/ladakhipedia-offline/
This is a brand new server run by the main developers of the project as a spin-off of mastodon.social It is not focused on any particular niche interest - everyone is welcome as long as you follow our code of conduct!
