Frequently Asked Before Contacting

Is the tool free? Yes, completely free. No signup, no credit card, no limit on how many UUIDs you generate.

Do you offer an API? A public REST API is on our roadmap. For now, all generation is client-side JavaScript which you can replicate from our JavaScript guide.

Can I use generated UUIDs commercially? Yes. UUIDs are mathematical outputs and carry no intellectual property restrictions. Use them freely in any project.

Why is my UUID not working in my database? Most likely a format issue — check whether your database expects hyphens or not, uppercase or lowercase, and whether it stores UUIDs as a native type or as a string. See our PostgreSQL guide and MySQL guide for specifics.
