Generate random UUIDs (v4) or time-based UUIDs (v7). Free, fast, and works entirely in your browser.
Generate random UUID v4 or time-based UUID v7 instantly. Create multiple UUIDs at once. Free, fast, and secure - runs entirely in your browser.
Select between UUID v4 (fully random) or UUID v7 (time-ordered). v7 is the modern standard for database keys as it supports chronological sorting.
Choose how many identifiers you need to generate at once (up to 100). Bulk generation is perfect for testing or initializing datasets.
Our tool use cryptographically secure random number generators (CSPRNG) in your browser to ensure absolute uniqueness and security.
Use UUIDs as unique identifiers in your database to prevent conflicts and enable easier data synchronization across distributed systems.
Generate unique correlation IDs for API requests and distributed logs to trace transactions across multiple services.
Quickly generate unique IDs for local development, UI testing, or populating mock JSON structures.
All processing happens directly in your browser. Your data never leaves your device — we don't upload, store, or have access to any of your content.
No server roundtrips means instant results. Once this page is loaded, the tool works even without an internet connection.
UUID v7 includes a timestamp, making them 'sortable.' When used as database primary keys, v7 UUIDs significantly improve write performance and reduce index fragmentation compared to random v4 UUIDs.
Yes. The probability of two UUIDs being the same as a result of random generation is virtually zero. You can safely use them for globally unique identification.
100%. All generation happens locally in your browser. We don't have a database of generated UUIDs, and we never see the IDs you create.
