Click Generate to create UUIDs

UUID v4 uses 122 random bits — the chance of a collision between two UUIDs is astronomically small.

Generated with crypto.getRandomValues — cryptographically secure, never sent to a server.

APIs tips

🔑

UUIDs make decent API key templates — 122 bits of randomness. For production secrets, combine with a hashing layer (e.g. SHA-256 + prefix).

💡

Format: use the UUID as the stored hash basis, strip hyphens for compactness, and prefix with your service name (e.g. sk_live_550e8400...).

🔐

Generated with crypto.getRandomValues — the same cryptographic API used in browser-based key generation. Not predictable or guessable.

📋

Generate in uppercase for readability in dashboards and support tickets. Uppercase UUID format is equally valid and often easier to read.
