About this tool
UUIDNow is built around one idea: you usually just need one UUID, fast. So the page generates it before you touch anything — no buttons, no forms. Click the big box (or press G) and it's on your clipboard.
Every identifier comes from crypto.randomUUID() or crypto.getRandomValues() — cryptographically secure randomness built into your browser. Nothing is requested from a server, so your UUIDs cannot be logged or observed by anyone. Need sortable IDs for a database? Switch to v7, which embeds a millisecond timestamp — see the v4 vs v7 comparison, or explore more tools at dec0de.dev.
