About This Tool
What this tool does
A UUID is a universally unique identifier used to create collision-resistant IDs across distributed systems, databases, APIs, and background jobs. This tool generates UUID v4 values instantly so developers can seed records, test integrations, and create mock payloads without relying on production identifiers.
- Use UUIDs for database primary keys, API payloads, event messages, and fixture data.
- Generate bulk identifier sets for tests, imports, seeded environments, and mock services.
- Copy or export the generated UUIDs in JSON, CSV, or SQL with clean monospace preview output.

A UUID is a universally unique identifier used to create collision-resistant IDs across distributed systems, databases, APIs, and background jobs. This tool generates UUID v4 values instantly so developers can seed records, test integrations, and create mock payloads without relying on production identifiers.
When should I use UUIDs in development?
Use UUIDs when you need globally unique identifiers for database rows, API resources, events, fixtures, or distributed systems where sequential IDs are not ideal.
Can I export data from the UUID Generator?
Yes. You can copy generated UUIDs or export them as JSON, CSV, or SQL for database seeds, fixtures, and automated tests.
