So on my search engine search (!
DDG: free, non-targeted (context-based) ads, bing based, poor results (arguably one can get used to).
Kagi: paid, feature-rich, much better search results.
DDG also has poorer performance, accessibility, and you guessed it, tech stack. VC-backed (a16z etc).
Kagi is more performant, accessible, self- & user-funded. Heavily invested into AI enhanced search. ♻️ unaddressed?
DDG does have a HTML version which drops the landing page size from 2.3mb to 27kb.
