A UUID (Universally Unique Identifier) is a 128-bit identifier that is unique across space and time. It's commonly used in software development for generating unique identifiers for database records, API endpoints, and system components.

What UUID versions are supported?

Our UUID generator supports all major UUID versions: v1 (time-based), v3 (MD5 hash-based), v4 (random), v5 (SHA-1 hash-based), v6 (time-ordered), and v7 (time-ordered with monotonic counter).

Is this UUID generator free to use?

Yes, our UUID generator is completely free to use. No registration, subscription, or payment is required. You can generate unlimited UUIDs without any restrictions.

Can I generate multiple UUIDs at once?

Yes, you can generate up to 10,000 UUIDs at once. The tool includes a virtualized list for efficient display of large datasets and supports CSV export for bulk operations.

Are the generated UUIDs truly unique?

Yes, UUIDs are designed to be globally unique. UUID v4 uses cryptographically secure random numbers, while other versions use timestamps and MAC addresses or namespace-based hashing to ensure uniqueness.

Can I use these UUIDs in production applications?

Absolutely! Our UUID generator creates standard-compliant UUIDs that are safe for use in production databases, APIs, microservices, and any application requiring unique identifiers.
