Generate standard UUIDs with count and case options
UUID Generator is a simple online tool for generating standard-format UUIDs (Universally Unique Identifiers). A UUID is a standardized way to uniquely identify information in computer systems, widely used in database records, distributed systems, API design, and more.
Whether you're a developer generating unique identifiers for database records or a tester creating mock data, this tool has you covered. Everything runs locally and nothing is uploaded, keeping your data secure. Curious what a UUID actually is and when to use one? Read our UUID guide →
