About this tool
What UUIDs are for
UUID v4 values work well as database keys, session IDs, test fixtures, and anonymous tokens. This tool generates standard random UUIDs locally in your browser, with optional batch copy for developers and QA.
Tips
Use a fresh UUID per test row to avoid shared state. Combine with a temporary email and the password generator for isolated test identities. See temporary email for developers.
