why genom
built for developers who need speed and precision
blazing fast
Grid-based spatial indexing delivers consistent sub-millisecond performance. Optimized binary format with string interning keeps memory usage minimal.
rich data
18+ fields per location including timezone, currency, postal code, region, continent, EU membership, and DST status. Everything you need in one call.
zero setup
Database builds automatically on first install. No downloads, no configuration files, no external dependencies. Just add and use.
thread-safe
Global singleton with lazy initialization. Lock-free reads mean zero contention in multi-threaded applications. Safe by default.
