UUID Generator

Generate cryptographically random UUIDs (Universally Unique Identifiers) directly in your browser — no server round-trips, no logging, no copy-paste guesswork. This free tool from Chat GPT5 supports the three versions developers actually reach for: UUID v1 (timestamp + node based, useful when you need ordered IDs), UUID v4 (fully random, the default for most modern systems and the one most ORMs assume), and UUID v7 (time-ordered random IDs that combine the best of both worlds and now play nicely with indexed database columns). Generate one ID, generate a hundred in a batch, copy them with a single click, or paste them straight into your code editor, terminal or SQL migration script. Everything runs locally in JavaScript using the Web Crypto API for true cryptographic randomness, so you can use the IDs in production code, database seeds, test fixtures or auth tokens with complete confidence. If you are building anything in modern software — from a side project to an enterprise-grade distributed system — fast, correct, freely available UUIDs are one of those tools you reach for more than you would expect.
