The fastest bulk UUID & ULID generator
AG UUID is a free tool that instantly generates the unique identifiers you often need in development and testing — no signup, no install.
It supports the standard UUID v4 (random) by default, plus time-sortable v7, time-based v1, the all-zero NIL, and the short, sortable ULID. You can create anywhere from 1 to 1,000 at a time.
Combine format options such as uppercase, no hyphens, and brace {} wrapping to copy them exactly how you want, with per-item copy, copy all and .txt download supported.
Every identifier is generated solely with your browser's crypto.randomUUID() / getRandomValues, and no input or output is ever sent to or stored on a server.
