About UUID Generator
Generate UUIDs online in bulk with this free UUID generator: create 1, 10, 100, or 1000 version 4 identifiers and copy or download them instantly. Random UUIDs suit primary keys, correlation ids, request ids, test fixtures, and seeding databases without collisions. Output is plain text so it drops straight into code, a CSV, or a SQL insert.
Backend developers mint ids for rows before an insert. Frontend developers stub entities in mocks. QA needs many unique values for parallel tests. Data people load a list into a spreadsheet. Version 4 UUIDs are random; they are not time-based UUID v1 and they are not name-based UUID v5. For most application keys and correlation ids, v4 is the usual choice.
Pick a count, generate, copy or download, and paste where you need them. Generating a thousand ids in the browser is faster than writing a loop when you only need a file of ids. If you need a memorable secret, use the password generator instead. If you need readable random text, use the random text generator.
Identifiers are generated in your browser using the secure random API and are never stored. There is no server log of the UUIDs you created. Use this free UUID generator and GUID generator whenever you need bulk unique ids privately and instantly.
