UUID / GUID Generator (v4 & v7)
Your version 4 UUID (GUID)
UUID (universally unique identifier) and GUID (globally unique identifier) are commonly used interchangeably. This tool generates RFC-compatible version 4 and version 7 UUIDs that can be used anywhere a GUID string is expected. (Note: some Microsoft APIs serialize a GUID's bytes in a different order, so the two aren't always byte-for-byte identical in binary form.)
UUID v7 adds a Unix timestamp prefix, so newer IDs sort after older ones and work well as database primary keys or append-friendly indexes. It is designed to stay monotonic within the same moment while still being unique. Choose v4 when you want a fully random UUID with no embedded ordering information.
