About LetsRandomize
The Story Behind LetsRandomize
Hi, I'm Sam Parker. I started LetsRandomize because I was frustrated with the state of random generator tools online. Most of them were either plastered with intrusive ads, looked like they were designed in 2005, or required unnecessary sign-ups to use basic functionality.
As someone with a background in data science and statistics, I understand the importance of proper randomization. Whether you are running a classroom activity, picking teams for a weekend game, generating secure passwords, or making a quick decision, the randomness should be fair and the tool should be easy to use.
Our Approach
Every tool on LetsRandomize is built with these principles:
- Client-Side Only: All randomization happens in your browser. No data is ever sent to a server.
- Cryptographically Secure: We use the Web Crypto API (crypto.getRandomValues) when available for true randomness.
- Mobile-First: Every tool is designed to work great on phones and tablets.
- No Sign-Up: All tools are completely free with no account required.
- Fast & Lightweight: No heavy frameworks or external dependencies. Just clean HTML, CSS, and JavaScript.
About the Technology
LetsRandomize uses a unified randomization engine built on top of the Web Crypto API. When your browser supports crypto.getRandomValues(), we use it for cryptographically secure random number generation. For older browsers, we fall back to Math.random(), which provides pseudorandom numbers suitable for most non-security applications.
The entire site is static HTML, CSS, and JavaScript. There is no backend server, no database, and no tracking cookies. Your generated results are stored locally in your browser using localStorage for the history feature, and you can clear them at any time.
