Qwant and Ecosia try to build their own index: https://techcrunch.com/2025/08/06/qwant-and-ecosia-debut-sta...
I do not believe that Qwant can produce something good, they always were a company to extract money from the french taxpayer to wrap bing results.
I use and enjoy Ecosia, it works pretty well for most use cases. Unfortunately it has the same limitation as Duck and basically all of the other non-enormous-players in the search engine market: Location aware search is garbage.
One the things I hate about Google is being forced to have location-aware search. I love how Kagi actually lets me override the country.
