UUID / GUID Generator (V4)
Generate one or more unique, random **UUIDs (GUIDs)** instantly.
When should you use this UUID / GUID Generator?
- Generate unique identifiers for database records
- Create IDs for APIs, events, or distributed systems
- Use UUIDs in frontend or backend testing
- When you need collision-free IDs instantly
Example use case:
You’re designing a database schema or building an API that requires unique identifiers for each record. Use this tool to generate secure Version 4 UUIDs instantly and copy them directly into your code or database — no setup, no dependencies.
Tip: UUID v4 values are random and ideal for distributed systems where uniqueness across services is critical.

UUID / GUID Generator FAQ
UUIDs are used as unique identifiers for database records, public IDs, distributed systems, and client-generated keys.
It generates UUID Version 4 (V4), which is random and widely used for general-purpose unique identifiers.
UUID v4 collisions are extremely unlikely. For practical applications, they are considered safe for uniqueness.
Yes. UUIDs are better than sequential IDs for public URLs, but they are not authentication tokens.
If the generator is client-side, it can generate UUIDs offline inside your browser.
If it uses a cryptographically secure random source (like Web Crypto), it is suitable for most applications.
