Options
Number generator 0–1
The 0–1 number generator creates random integers in a given range. Only 2 possible values: 0 or 1. Perfect for coin tossing.
Each number from 0 to 1 has equal probability. The cryptographic Crypto.getRandomValues() API ensures true randomness. Zero-knowledge architecture — numbers never leave your device.
Client-side generation. Set the count, exclude duplicates, sort the result. The tool works offline after the page loads. Free, no registration required.
Features
- Numbers in range 0–1 only
- Customizable result count
- Exclude duplicates
- Zero-knowledge: data never leaves your device
- Cryptographic API — true randomness
- Instant result copying
How it works
Get a number from 0–1 in four steps
An intuitive interface lets you get results in seconds.
01
Range already selected
The range 0–1 is already set. The generator only creates numbers within these limits.
02
Set the count
Specify how many numbers to generate — from 1 to 100. The tool adapts to your choice.
03
Run generation
Click the button. The cryptographic algorithm creates random numbers in the 0–1 range.
04
Copy the result
Numbers appear instantly. You can copy them one by one or all at once.
Applications
Where numbers from 0–1 are needed
Random numbers in a given range are a versatile tool.
Giveaways
Fair winner selection from the 0–1 range. Each number has equal chances.
Games
Random numbers for games needing the 0–1 range. A replacement for dice and generators.
Education

No limits
Generate as many times as you want. The tool is completely free with no registration.
Frequently asked questions
About numbers from 0–1
What numbers are in the range?
The range 0–1 includes all integers from 0 to 1 inclusive. 2 values total.
Are the numbers truly random?
Yes, it uses Crypto.getRandomValues() — a cryptographic API that ensures true randomness.
Can numbers repeat?
By default, yes. To prevent repeats, enable the no duplicates option.
How many numbers can be generated?
From 1 to 100 numbers per generation. With the no duplicates option enabled, no more than the count of numbers in the range.
