Hey Product Hunt! I built DevToolsBR to solve a real problem I had as a developer — generating valid test data for international apps. The highlight is the national ID generator: it supports 20+ countries with mathematically correct algorithms (Modulo-11, Luhn, Verhoeff). Generate CPF, SSN, CURP, DNI, Aadhaar and more in seconds. Would love to hear your feedback. What tools would you like to...
