UUID Generator creates version 4 identifiers when you need unique keys for database seeds, analytics events, or client-side correlation IDs without calling a backend.
Set Count, click Generate, then Copy the textarea list. Raise the count when a fixture file needs a batch of IDs in one pass.
Generation uses browser randomness suitable for typical app identifiers, not for specialized cryptographic key material beyond UUID v4 norms. When a demo database needs dozens of primary keys quickly, raise Count once instead of clicking Generate repeatedly for each row.
What UUID Generator does
Create one or many UUID v4 values on demand.
- Numeric count field
- Generate action for UUID v4 values
- Multi-line readonly output
- Copy control for the full list
- Hint describing expected usage
Who UUID Generator is for
- Backend developers seeding tables
- Frontend engineers assigning temporary client IDs
- QA building repeatable yet unique fixture rows
- Writers documenting example identifiers in APIs
How to use UUID Generator
1. Open UUID Generator on beeforge.dev.
2. Enter how many IDs you need in Count.
3. Click Generate.
4. Copy the output list into your seed file or ticket.
Features
- Batch generation in a single click
- Line-oriented output for easy pasting
- No server round trip to mint IDs
- Simple count control without extra modes
- Pairs with hash tools when you need digests too
Examples
- Mint ten UUIDs for a demo tenant seed script.
- Create a correlation ID while reproducing a support case.
- Fill placeholder primary keys in a local JSON document.
- Create five UUIDs for linked order, customer, and payment fixture rows that must stay stable during a workshop.
Tips and limits
- UUID v4 values are random; they do not encode timestamps like some other versions.
- Do not assume global uniqueness across offline generators without accepting collision probability.
- Uppercase vs lowercase formatting may matter to strict validators; normalize if required.
- Avoid using UUIDs as security secrets; they are identifiers, not passwords.
- Store generated UUIDs in your seed files rather than regenerating them every run if referential integrity across tables matters.

FAQ
Which UUID version is this?
Version 4 random UUIDs, as produced by typical browser crypto random helpers.
Are IDs sent anywhere?
No. Values are generated locally in the page.
Is there a maximum count?
Keep counts reasonable for the textarea. Extremely large batches belong in a script.
Can I generate UUID v1?
This tool focuses on v4. Use another generator if you specifically need time-based versions.
Why did two runs collide?
Collisions are extremely unlikely at normal volumes. If you see duplicates, check that you are not reusing a copied block.
