I would like the option to use MetaGer and Whoogle as default search engines.
No shade to Kagi; I am playing around with all these new search engines that are popping up. MetaGer is a cool, open-source, privacy-oriented option, run by a non-profit and focused on diversity. They also use 100% renewable energy. I am sure many people would love to have it as an option! I believe they do have ads, but there is some explanation on how all of that works while maintaining privacy. If you would like to learn more, I would suggest visiting their website!
When I click Install MetaGer, I am taken to this page.
As for Whoogle, they are a front-end for Google for those who want Google search results, but want to avoid the tracking. Other Whoogle instances can be found on this GitHub.
