Maintaining In-House GeoIP Databases is a Pain

Hosting 100MB+ MaxMind MMDB binary files inside container images adds memory bloat and requires monthly manual update cron jobs.

High Roundtrip Latency from Centralized APIs

Calling centralized REST geolocation endpoints adds 150ms+ TTFB to every single server-rendered request.
