Input

Collision probability

256 bits of entropy. At 1000 IDs per hour, ~1% collision probability after 4.8244e+34 hours (4.8244e+37 IDs). Birthday-bound approximation assuming independent, uniform IDs; small-space estimates are only indicative.

NanoID uses 64 URL-safe symbols and secure randomness. Processing stays in this browser; nothing is uploaded or stored. NanoID · ULID specification
