Modern ID Generator

Generate UUIDv7, ULID and NanoID identifiers in bulk with crypto.getRandomValues, and decode the timestamp inside a UUIDv7 or ULID.

How to use Modern ID Generator

  1. 1

    Choose an ID type

    Select UUIDv7, ULID, or NanoID. UUIDv7 and ULID are time-sortable; NanoID is a compact, URL-safe random string with a configurable alphabet and length.

  2. 2

    Set count and options

    Enter how many IDs to generate, from 1 to 100. For NanoID, customize the alphabet and length to match your collision and readability requirements.

  3. 3

    Generate and copy

    Press Generate to create the batch using cryptographically secure randomness, then copy a single ID or use Copy all to grab the entire list.

  4. 4

    Decode a timestamp

    Paste a UUIDv7 or ULID into the decode panel to read its embedded creation time as an ISO date plus a human-readable relative time.

Questions and answers

What is Modern ID Generator?
UUIDv7 and ULID are identifiers that begin with a millisecond timestamp, so they sort by creation time; NanoID is a short random ID with a configurable alphabet. This generator creates any of the three in bulk with crypto.getRandomValues and decodes the creation time in a pasted UUIDv7 or ULID.
Is Modern ID Generator free?
Yes. It runs entirely in your browser at no cost, with no account, so you can generate IDs for tests, fixtures, or production seeds anytime.
Does Modern ID Generator store or send my data?
No. IDs are produced locally with the Web Crypto API and nothing is uploaded. Decoding a pasted ID also happens entirely in your browser.
Why choose UUIDv7 or ULID over UUIDv4?
UUIDv7 and ULID embed a millisecond timestamp in their leading bits, so they sort chronologically and index better in databases than random UUIDv4 values.
