Entfer uses an independent index, to avoid starting off with a strong bias defined by search giants and the SEO industry.
It’s currently at an early prototype stage. The index is growing but still small, and many important features do not exist yet, such as exact phrase searching, but they are coming soon.
It is very fast, the speed reminds me of that of rightdao.com.
Can you give a bit more information about your tech stack, crawling and ranking?
Who is behind is and what is the business model intended to be?
Much of it is not yet well defined or still subject to rapid changes (in terms of tech and business model).
I definitely want search to be free and open, usable without an account. Perhaps there could be an optional paid membership to remove ads, but that is not yet in the pipeline.
I believe Kagi uses Google and Bing behind the scenes, which allows it to be on par with them, but it also ultimately leads to being more dependent on them, with less flexibility.
