I'm building a DX-focused IP-Geolocation service https://ip-sonar.com/

Slowly but steadily, I'm building not a rocket or AI science but a boring (and reliable) IP Geolocation Service: https://ip-sonar.com
It has a rich free tier, simple API, and a client dashboard that is easy to use. I do my best to build a service that I would love to use as a software engineer.

- 30k requests/month for free
- simple, stable, and fast API
- MCP Server for AI-related workloads
Easy, fast, reliable IP Geolocation service. Recently, I've added the MCP Server.

This is cool - how does IP geolocation work? How do you know that xyz IP is at this particular spot?
Edit: I see you are using MaxMind database - do you add some sort of additional analytics or overlay on top of that?
At this moment, I'm still very early with the service, I don't do any serious data crunching on my end (but I plan to).
Because I love building APIs and backend services, I built a simple IP geolocation service with the best developer experience. It has free (rate-limited) access and affordable paid tiers. Check it out: https://ip-sonar.com
Unlimited free seems great!
I'm also building an IP Geolocation service with a generously free tier. I focus on DX and simplicity: https://ip-sonar.com - still in build phase, but the API is working.
