About
Server Radar tracks Hetzner's dedicated server auction and cloud availability. It provides historical pricing data, advanced filtering, and configurable alerts to help you find servers that match your requirements and budget.
The project is open source. Data queries run client-side using DuckDB for fast filtering, while the backend handles alerting and user accounts.

I'm Simon, a software engineer based in Germany. I built Server Radar to solve a problem I had: tracking Hetzner auction prices over time and getting notified when specific configurations became available.
The tool grew from a simple script into a full application. I've open-sourced it so others can use it, audit the code, and contribute improvements.
