When I had a look on it a while ago they didn’t support Docker Compose. But except this it’s a drop in replacement.

I use Reeder on iOS and Mac.

Problem is that this kind of alternative web interfaces for Google are just going web scraping of the regular www.google.com page. They are not using the Google Search API (which is paid and requires an API key). However, Google says scraping of their search results is not allowed. And they are actually preventing it by blocking IPs doing too many search request in certain amount of time. That is the main reason a lot of Searx or SearxNG instances stop working after a certain time.
