What this tool does & how to use it
What is this tool?
This tool generates UUIDs (Universally Unique Identifiers), also known as GUIDs. Each UUID is a 128-bit value usually displayed as a standard 36-character string (e.g. with hyphens). UUIDs are used as unique IDs in databases, APIs, and distributed systems.
UUIDs are designed so that the chance of two being the same is astronomically low, even when generated on different machines.
How to use it
Open the tool and click to generate one or more UUIDs. Copy the value(s) you need into your code, config, or database. Use "bulk generate" if you need many at once.
Benefits and use cases
No signup; generation happens in the browser. Useful for creating unique IDs for records, API tokens, or file names. Common in development, testing, and system design.
