It looks like a few people are recommending this, so just a quick note in case people are unaware:

If you want to avoid being tracked, this is not a good solution. Searxng is a meta search engine, meaning it is effectively a proxy: you search on Searxng, it searches multiple sites and sends all the results back to you. If you use a public instance, you may be protected from the actual search engine*, because many people will use the same instance, and your queries will be mixed in with all of them. If you self host, however, all the searches will be your own - there is then no difference between using Searxng and just going to the site yourself.

*The caveat with using the public instances is while you may be protected from the upstream engine, you have to trust the admins - nothing stops them from tracking you themselves (or passing your data on).

Despite the claims in their docs, I would not consider this a privacy tool. If you are just looking for a good search engine, this may work, and it gives you flexibility and power to tune it yourself. But it's probably not going to do anything good for your privacy, above and beyond what you can get from other meta search engines like Startpage and DuckDuckGo, or other "private" search engines like Brave.
