UUID Generator

About UUID Generator

The UUID Generator creates RFC 4122 version 4 Universally Unique Identifiers for database keys, correlation IDs, and client-side entity IDs. Backend and frontend developers use it to batch-generate random IDs in lowercase or UPPERCASE without writing a one-off script.

• v4 UUIDs are random—do not expect sequential ordering for pagination.
• Match the casing your database or API already stores to avoid duplicate-looking IDs.
• Copy All when seeding fixtures so you keep a consistent set across environments.
