This is also „only“ a meta search engine, meaning it will use the search index of others and will proxy your search to them.

I say only, because alternatives do exist. mojeek is UK based and has its own search index (although not the best imho), then there is other search engines that proxy requests like qwant (French), ecosia (German), searxng (OSS; selfhosted and public instances available).

I don’t know what the mission with this new search engine here is and what it offers that others don’t. You lose 5€ and tether yourself to an account that definitely makes you identifiable.

Metager is another search engine that sort of wants you to have an account but rather go for an access token. They are operating as a German non profit and have been operating since 1996!
