UUIDv7 tips

🕒

UUIDv7 stores a 48-bit Unix millisecond timestamp in its first bits — decoded here as a readable date.

📈

Because the time leads, v7 UUIDs sort chronologically, which is great for database keys.

🔍

Handy for debugging: see exactly when a record with a given v7 ID was created.

🔒

The ID never leaves your browser.
