About this tool

IconVault's UUID Generator creates cryptographically secure version 4 UUIDs using the browser's built-in crypto.randomUUID() - the same API Node.js and Deno use. Generate 1, 10, 50 or 100 at a time in v4 or time-ordered v7 (RFC 9562) - the modern default for database keys - with uppercase and no-dashes format options. Copy any single UUID with one click, or copy the whole batch as newline-separated text for seeding databases, configs and fixtures.

Because generation happens locally with the platform's secure random source, UUIDs are never sent over the network or stored anywhere - safe for API keys, session identifiers and test data. Every visitor gets 5 free generations - IconVault Pro ($12/year) unlocks unlimited use of every developer tool.
