Generate UUID values with `crypto.randomUUID()` when available, inspect the version and variant fields, and create multiple IDs at once.
Generate between 1 and 16 UUIDs per run.
Generated with crypto.randomUUID().
The primary path uses `crypto.randomUUID()` to create version 4 UUID values directly in the browser.
If that API is unavailable, the tool falls back to random bytes, sets the version and variant bits manually, and formats the result in canonical UUID form.
This tool produces version 4 UUIDs, which are randomly generated identifiers.
Those bits confirm the UUID follows the expected structure and help you inspect the generated format.
For many browser-based workflows, yes. Full production suitability still depends on how your broader system manages identity and collisions.
They are useful for fixtures, object IDs, mock API data, database keys, and distributed identifiers.
UUIDs are designed to be unique enough for many distributed and offline generation workflows.
Version 4 UUIDs encode randomness rather than timestamps or hardware addresses.
Using the built-in Web Crypto API is preferable when the browser provides it.
