Not sure it will solve your problem, but if you’re not happy with the public SearXNG instances, you can run your own instance of SearXNG on your local machine, and even set up custom filters and redirects to get rid of SEO junk.
What issues did you have with SearXNG?
You could try to self host it, or even just run it on your local machine.
Shameless plug on how to set it up locally, and how to set up custom filters (to block junk websites and redirect reddit to the old interface).
I see you already have an answer using podman.
But don’t be afraid of the command line. If you can copy/paste a few commands, it’s pretty easy to set up.
I honestly find installing docker harder than to start a locally hosted searxng instance.
Also, something like self-hosting your own email is way harder and requires a lot more maintenance. I’d leave that project to further down the line.
