Tool usage guide
Generate unique identifiers instantly with our versatile UUID generator, supporting v1, v4, and v5 standards for your development and database needs.
Background
Setting up a new user table and needing 50 unique IDs for initial testing.
Problem
Manually creating unique strings is error-prone and slow.
How to use
Select UUID v4, set the count to 50, and click generate.
version: v4, count: 50Outcome
A list of 50 unique, random UUIDs ready to be copied into the database script.
Background
Need to generate consistent IDs for internal resources based on domain names.
Problem
Standard random UUIDs don't allow for re-generating the same ID for the same resource.
How to use
Select UUID v5, choose the DNS namespace, and enter the resource name.
version: v5, namespace: dns, name: example.comOutcome
UUID v1 is time-based and includes the node's MAC address, while UUID v4 is generated using random numbers.
Yes, you can specify the count field to generate up to 100 UUIDs in a single batch.
A namespace is a predefined UUID used as a seed for v5 generation, ensuring that the same name always produces the same UUID.
UUID v4 provides a high degree of randomness, making collisions statistically improbable for most applications.
No, this is a web-based utility that runs directly in your browser.
A consistent, deterministic UUID that will always be generated for the input 'example.com' within the DNS namespace.
