Professional UUID Generator Tools
The industry standard for generating unique identifiers. From modern v7 timestamp-sorted IDs to classic random v4 strings.
Why Choose Karuvigal for UUID Generation?
RFC Compliance & Standards
Karuvigal's generation engine is strictly built to follow RFC 4122 and the newer RFC 9562 specifications. This ensures that every ID you generate is perfectly compatible with enterprise databases like PostgreSQL, MySQL, and distributed systems like Kafka or gRPC microservices.
Special Focus: UUID v7
We strongly recommend UUID v7 for all new database primary keys. Its time-sequential prefix prevents B-tree fragmentation, offering significantly better write performance than random v4 IDs.
Zero-Trust Privacy
Unlike other web tools, Karuvigal generates all identifiers locally in your browser. We do not transmit your generated IDs to any server. This is critical for generating API keys, internal object IDs, or any sensitive identifier where privacy and security are non-negotiable.
