The best options would be an open source, donation supported search engine, but the money required to host/develop that is immense.
We are all freeloading off of Lemmy right now, unless you are donating to the people who are running the servers. The cost to run a search engine is much higher though – kagi pays (iirc) double digit cents for each search, even before development costs, with the average user doing 700 searches a month. The costs are way higher.
