About UUID Generator
UUID Generator creates random, RFC-4122-compliant version 4 UUIDs in bulk — up to 200 at once — using the browser's native cryptographically secure random number generator. UUIDs are commonly used as unique identifiers for database records, API keys, session tokens, or any system that needs a guaranteed-unique ID without coordinating with a central server to avoid collisions.
