About the UUID Generator
UUIDs (universally unique identifiers) are the 36-character strings databases, APIs and distributed systems use to name things without coordination. This tool generates version 4 UUIDs — 122 bits of cryptographic randomness per identifier — using your browser’s built-in CSPRNG, so the values are suitable for production keys, session tokens and test fixtures alike.
Need identifiers in bulk? Hit “Generate 10” as many times as you like and copy the whole session list in one click. With roughly 5.3 × 10³⁶ possible v4 UUIDs, the chance of a collision in any realistic dataset is effectively zero.
How to use it
- 1Click Generate for a single UUID, or Generate 10 for a batch.
- 2Copy the highlighted UUID, or any earlier one from the session list.
- 3Use Copy all to grab every UUID generated this session, one per line.
