Online UUID Generator - Version 7

UUID Version 7 is a time-based UUID that uses a Unix timestamp combined with random bits. It is designed to be sortable by creation time while ensuring high uniqueness and randomness, making it suitable for modern use cases that require both chronological sorting and secure identifiers.

Pros:

• Chronologically Sortable: Uses a timestamp prefix, allowing easy sorting by time of creation.
• High Entropy: Combines timestamps with random bits for improved uniqueness without privacy concerns.

Cons:

• Limited History: Relies on Unix timestamps, which may not be suitable for applications needing historical dates far in the past.
• Not Deterministic: Includes random bits, so it does not produce the same UUID for the same input conditions.

Best for: Use cases that require sortable, time-based IDs with a high degree of randomness, such as event logs, database indexing, or session tracking.
