I Made a Ultra-Low Latency IP Geolocation API in Go
Hey! I'm a solo developer having fun learning Go. I have a side hustle and wanted to implement currency localization. I could use existing IP databases, but hosting on serverless is slow. So I built my own. I was surprised how fun it can be to use Go, and it's fast. Thankfully, Go's speed makes up for my dodgy code. Anyway, I'd love to get some feedback on my website/API. After a few weeks of testing and losing money on ads, I'm confident it's very reliable. This isn't a promo. It's basicly free (30k lookups/month), so there's no need to pay. Any advice or tips on how to grow and…
In plain words
An IP geolocation API built in Go that identifies user location for currency localization and other purposes. The service emphasizes low latency performance, particularly for serverless deployments. It offers a free tier of 30,000 monthly lookups with paid options available. Designed for developers integrating location-based features into their applications, this tool prioritizes speed and reliability over feature complexity.

I wasn't quite sure if this qualified as "Show HN" given you can't really download it and try it out. However, dang said[0]: > If it's hardware or something that's not so easy to try out over the internet, find a different way to show how it actually works—a video, for example, or a detailed post with photos. Hopefully I did that? Additionally, I've put code and a detailed guide for the netboot computer management setup on GitHub: https://github.com/kentonv/lanparty Anyway, if this shouldn't have been Show HN, I apologize!
