The UUID / NanoID Generator is a fast and secure utility for creating unique identifiers right in your browser. It supports both UUID v4 — the universally recognized random identifier format — and NanoID, a modern, compact alternative designed for performance and collision resistance.
Whether you're building APIs, generating test data, or assigning keys to records in a database, these identifiers ensure consistency and uniqueness across your system. The tool runs entirely on the client side, so your generated IDs never leave your device.
Use it to quickly generate multiple IDs for your JavaScript, Node.js, or backend projects without installing dependencies or writing a single line of code. The UUID / NanoID Generator makes randomness simple — and reliability automatic.
