@cbortech/uuid is a type-safe TypeScript library for parsing and generating UUIDs (versions 1–8, RFC 9562). Generate random UUID v4 or monotonic UUID v7, or paste any UUID to see its version, variant, embedded timestamp, and field layout. Everything on this page runs in your browser using the library itself.
npm install @cbortech/uuid
Press Generate to create UUIDs. UUID v7 values generated in the same millisecond are monotonically increasing. Click a UUID to inspect it below.
The variant occupies the top bits of its hex digit; the remaining bits of that digit belong to the following field. Field values above are bit-exact.
