Generators - Free Online Tools

Generate UUIDs, QR codes, lorem ipsum, random data, and other values you need for development, testing, or content creation. From creating unique identifiers to generating test data, these tools produce the values that software development requires.

All generation happens locally in your browser. Random values use cryptographically secure methods. Nothing gets logged or sent anywhere.

Available Tools

UUID Generator

Why Use Generator Tools?

Every developer needs to generate things. Unique IDs for database records. Test data for development environments. Placeholder text for designs. QR codes for testing. URL slugs for clean links.

Writing code to generate these values is tedious and error-prone. A UUID generator that doesn't follow RFC4122 properly might create collisions. A password generator without enough entropy creates weak passwords. These tools handle the complexity and edge cases for you.

They're especially useful during development and testing. Need 50 test user accounts? Generate them. Need unique identifiers for a migration script? Generate them. Need placeholder text for a mockup? Generate it instantly.
