⚡Generators
Generators create ready-to-use data — strong passwords, QR codes, test documents, names, colors and more. They are handy for developers seeding a test database, for anyone who wants a truly random password, or to build a Pix QR code in seconds. They all run in your browser, sending nothing to any server.
