WhoIR is a lightweight Geo IP API built with Go. It focuses on performance, simplicity and observability.
The name WhoIR is a play on identification.
In our logo, IR stands for the connection between the observer and the observed:
the English I (the self) and its mirrored reflection, the Cyrillic Я (R).
WhoIR(Я): We bridge the gap between a raw IP address and a real-world identity.

• Optimised for low memory footprint
Built-in metrics expose latency, runtime statistics, request distribution and live throughput.
Peak throughput under 1,000 concurrent connections.
Response time measured at the edge gateway.
Zero failed requests during high-load stress test.
