I built a free online tool for generating and validating Brazilian CPF (Cadastro de Pessoa Física) numbers using the official Brazilian algorithm.

Key features: - Generate valid CPF numbers (single or bulk) - Region-specific or random generation - Built-in CPF validator - Automatic formatting, one-click copy, and TXT download - Clean, responsive interface

Useful for developers working with Brazilian systems, testing, or anyone needing valid CPF numbers for legitimate purposes.

Would love to hear feedback from the HN community!
