For me, DuckDuckGo was supposed to represent private (not selling user data), unbiased (i.e. apolitical), fast search results. Ideally a replacement would meet as many of these goals as possible. Some alternatives I'm aware of:

* Searx - https://searx.github.io/searx/

* Brave search - https://search.brave.com/

Note this is not a discussion about the morality of DuckDuckGo's recent actions.
