What is UUID Generator?
UUID Generator is an online developer tool that creates universally unique identifiers following the RFC 4122 standard. UUIDs are 128-bit numbers used as primary keys in databases session tokens API request IDs distributed system node identifiers and any scenario requiring collision-free unique values without a central coordinating authority. This UUID generator supports multiple versions v1 time-based with MAC address v4 randomly generated the most commonly used variant and v7 time-ordered UUIDs ideal for database indexing and sortable record IDs. Generate single UUIDs or bulk quantities up to ten thousand at once with output in lowercase uppercase or hyphen-stripped formats. All generation happens locally using cryptographically secure randomness guaranteeing the uniqueness and unpredictability of every UUID produced.
When to Use UUID Generator
Use when creating database primary keys, API request IDs, session tokens, distributed system identifiers, or anywhere collision-free unique IDs are required.
How to Use UUID Generator
Select UUID version v1, v4, or v7, set the quantity needed, choose output format, and click generate. Copy individual UUIDs or download the entire batch as a text file.
