UUID Generator

Generate random Version 4 UUIDs.

Generate version-4 (random) UUIDs in bulk. Unique identifiers for your database or testing.

Why This Tool Exists

Universally Unique Identifiers (UUIDs) are standard 128-bit labels. Developers need them constantly for mocking data, generating API keys, or assigning IDs.

I needed 50 UUIDs to populate a test database. Manually typing them is impossible. This tool generates thousands instantly.
