Why on earth would I pay $10 a month for search when I can get everything I need using SearXNG? For Free.
It costs me exactly $0.00 to run SearXNG locally using Podman and WSL to host the docker image. It Just Works; and I don't have to worry about paying money every month to anyone; nor do I ever have to count my search queries as precious.
Unfortunately this "$10/month = Unlimited" is also likely to be available only for a limited time; and once Kagi feels it has enough users; then you'll be stuck back on some arbitrary number of searches each month.
Worse is logging in. To search. Yuck.
There are so many "Public" SearXNG instances as well for the less-than-technical; https://searx.space/
All of them provide the option(s) to use whatever engines you'd like.
