Frequently asked questions
What is a UUID?
UUID (Universally Unique Identifier), also known as GUID, is a 128-bit identifier used to uniquely identify data in databases, APIs, and distributed systems. UUID v4 is randomly generated.
Are these UUIDs truly random?
Yes. We use the browser's crypto.randomUUID() API which is cryptographically secure. The chance of collision is astronomically low.
What is UUID v4 vs other versions?
v4 is random-based (most common). v1 is timestamp-based. v3 and v5 are namespace-based. v4 is preferred for most applications since it does not leak any information.
Can I generate GUIDs for SQL Server?
Yes, UUID and GUID are the same thing. Use the "With braces" format for SQL Server compatibility.
