UUID Generator
Generate UUID v4 (random) and v7 (time-ordered) identifiers — cryptographically secure, all client-side
Count:
Random — cryptographically random 122-bit UUID. Most common choice.
UUID
UUID v4: 122 bits of cryptographic randomness — collision probability is astronomically low
UUID v7: Starts with the current millisecond timestamp so UUIDs sort chronologically — ideal for database indices
All generation uses the Web Crypto API and never leaves your browser
