Our template currently supports Bing, DuckDuckGo, Google, Kagi, Searx and Startpage. It also includes github/stackverflow presets taken from the uBlock-Origin-dev-filter project.
I understand why I need a sign up to use Search, so they at least can have a subscription model - but that seems like a barrier for entry and also the necessity to instill a lot of faith into a product that hasn't garnered trust (yet, rightfully so)
I love blocking domains without uBlacklist.
