Global Data for Modern Apps
LocaleDB is a comprehensive, open-source database of localization data for developers building international applications. We aggregate and process data from authoritative sources including CLDR, ISO standards, and OpenFlights.
The Challenge
Currency symbol placement (before or after?)
Date format differences (DD/MM vs MM/DD)
Number separators (1,250.00 vs 1.250,00)
Address formatting conventions
Time zones and calendar systems
Scattered documentation & heavy libraries
