Need a unique ID? Don’t just use a random number. Use a standardized UUID (Universally Unique Identifier). We support Version 4 (random) and the new Version 7 (time-ordered).
Why v7 is the New Standard
If you are building a database, use UUID v7. Unlike v4, v7 is lexicographically sortable by time. This makes database indexing significantly faster while maintaining uniqueness. I’ve switched all my new projects to v7 for this reason alone.
Privacy First
Some generators use your MAC address (v1), which is a security risk. Our v4 and v7 generators use cryptographically strong random values or timestamp-based entropy to ensure your hardware identity is never leaked.
