Hi HN, Ruurtjan from nslookup.io here. Ask me anything.
I'm also happy to give feedback on any side project (idea) you're working on.

1. Ads through Ethical Ads or Carbon Ads. This is what I have with nslookup. It's at $500/month on these volumes: https://plausible.io/nslookup.io
2. An exclusive ad deal with a complementary service. That's what I have with whoismyisp.org. Think about what people are working on when they visit your tool, then find a service that they'll need right after that task.
3. Donations
4. Sell a course. i.e. "DNS for developers" for nslookup.io.
5. Add a paid API. i.e. DNS lookup API for nslookup.io.
6. Add a SaaS that does something similar, but more complex. i.e. monitoring DNS records for nslookup.io.
