About this Tool

Bulk generate cryptographically secure UUIDs and GUIDs.

1UUID v4 vs v7

A UUID (Universally Unique Identifier) is a 128-bit label used for information in computer systems. Version 4 UUIDs are completely random, while the emerging Version 7 UUIDs are time-ordered, making them ideal for database primary keys that need to be sortable by creation time.

2Example: Bulk Generation

Generate 100 UUIDs instantly: `550e8400-e29b-41d4-a716-446655440000`

3Cryptographic Randomness

Unlike many online generators that use basic `Math.random()`, our engine uses the browser's `crypto.getRandomValues()` API. This ensures that the generated IDs meet rigorous cryptographic standards for randomness and are practically guaranteed to be unique.

4Privacy: Local ID Generation

Generating primary keys for a private database? Our engine runs 100% in your browser. No IDs are generated on a server, preventing any risk of "ID sniffing" or tracking of your application's internal structure.

Privacy Guarantee

Secure Devutils operates exclusively in your browser using local web workers and JavaScript. Your source code, configurations, and sensitive text payloads are never transmitted across the network or stored on any external servers. It is completely safe for air-gapped environments.
