metaGer is a German search engine that works as a metasearch: it queries several other search providers and combines what they return into one result list. It is run by a non-profit association, its source code is open, and the project puts a lot of weight on protecting the privacy of the people searching.
metaGer is hosted at Hetzner in Germany on servers powered by green electricity, so it is both a European alternative to the American search engines and a low carbon one. It fits people who want search results without a profile being built around them.
Pricing
Ad-free searching works with tokens: each search costs one token, and 500 tokens cost 5 euro.
