About Random Tools
A free, private, and lightweight collection of randomizer utilities — built for everyday decisions, games, classrooms, and more.
What is Random Tools?
Random Tools is a web-based suite of randomization utilities. Whether you need to generate a random number, roll virtual dice, shuffle a list, draw a card from a deck, or flip a coin, we've got you covered.
Originally built as a native iOS app, this web version brings the same functionality to every device with a browser — no app install required.
Our Tools
How It Works
All randomization is performed in your browser using the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random numbers. This means results are truly unpredictable and unbiased.
The entire application is built with pure HTML, CSS, and JavaScript — no frameworks, no build tools, no server required. Pages load instantly and work offline once cached.
Privacy First
We take a simple approach to privacy: don't collect data in the first place.
- No cookies or tracking scripts
- No analytics (no Google Analytics, no Mixpanel, nothing)
- No server-side data storage
- No user accounts or login
- All preferences and history are stored in your browser's localStorage
