UUID / GUID Generator

Generate cryptographically secure 128-bit Universally Unique Identifiers (UUID) and Globally Unique Identifiers (GUID) with the UUID / GUID Generator. Compliant with RFC 4122 and RFC 9562 standards for distributed database primary keys, microservice request tracing, telemetry tags, and software engineering.

Supports multiple UUID specifications: UUID v4 (Cryptographically Random), UUID v7 (Time-Ordered Epoch Timestamp)—the modern gold standard for high-performance B-tree and database indexing with chronological locality—and UUID v1 (Timestamp & Node MAC).

Features customizable formatting: standard hyphenated (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx), compact without hyphens, uppercase or lowercase, curly braces ({...}) for Microsoft GUIDs, batch generation up to 500 IDs at once, and 1-click export to JSON, CSV, or plain text.
