Swisscows does use Bing, Startpage uses Bing and/or Google depending upon where you are, we are fully independent: https://www.searchenginemap.com/ is a visualisation that might be useful
So is Mojeek a standalone since it's yellow? It looks like a lot of other people use them and not the other way around. Yep is cool, but I think they get their money from the sites that pay them? I looked at it yesterday, it's sort of a strange set up that I'm not sure I understand.
yes we are indeed a standalone, the sizes of bubbles are reflections of the number of index-usage relationships
yep is attached to ahrefs: https://techcrunch.com/2022/06/03/yep-search-engine/ where I can speak to where results come from, I couldn't tell you about their model
Mojeek gives good results, I'll keep trying it. I'm not sure about yep though, how do the people get paid? I didn't see any sign up. It sounds like it's a platform for their SEO subscribers.
sorry for taking a while to get back but the main source of mojeek revenue is api sales, having people pay to access results for different applications (bing does similar i.e. duckduckgo, qwant, ecosia)
