UUID v4 is the most commonly used UUID type. It is randomly generated and designed to be globally unique without requiring a central counter, making it ideal for distributed systems, database IDs, and API request identifiers.

• Generate one or multiple UUIDs.
• Use uppercase or remove hyphens if required by your system.
• Copy the output for databases, configs, or JSON payloads.

Tip: for time-ordered identifiers, consider UUID v7.
