@poundik I don't really found Wikipedia source code, only thing I found was MediaWiki source code: https://github.com/wikimedia/mediawiki, yeah, they are collaborating, but that doesn't mean they both are open source.
About Odysee, you can get only front-end web part, if you downloaded desktop client, you can get itself source code, but back-end still is proprietary, there is reason why I added Odysee too.

First, I don't really know much of alt front-ends, second thing is, I'm trying to found non-JS websites, not software and websites both.
Er, Wikipedia is already open source. Odysee is too.
