I self-host a SearXNG instance that is public facing. On a VPS. I share it with friends and family, and I do not mind if some strangers use it as well.
What I’m afraid of is getting my IP rate limited or even blacklisted by search engines. I would like to keep the instance public facing for UX reasons (no VPN, no SSO).
I enabled SearXNG internal limiter, which I’m not sure what it does.
Additionally, I am rate limiting at the reverse proxy level (Caddy) as follows:
rate_limit {remote.host} 10r/s
rate_limit {path.*} 50r/s
That is, 10 requests per second for a single IP address, and 50 requests per second in general.
Would you have improvements to suggest me, or further measures I could take?
Edit: I’m not using Cloudflare or any similar solution and I want to avoid it.
