UUID or ULID

💡 Versions 1, 6, and 7 (and ULIDs) embed a creation time, which is decoded above. Versions 4 are fully random and carry no timestamp. Everything is parsed in your browser.

debugging tips

🐞

Pasting an ID tells you its type, version, and (if time-based) when it was generated — useful when tracing an issue.

🧭

Confirm whether IDs in a system are random (v4) or time-ordered (v1/v6/v7) before relying on their sort order.

🔌

Pairs well with the UUID Generator when you need to create new IDs of a specific version.

🔒

Production identifiers are inspected entirely on your device.
