Pick a number
Enter where the range starts and ends, then choose Generate number. Both ends count. Negative numbers work, up to one billion in either direction.
Fair across the whole range
The browser’s cryptographic random-number API supplies each draw. Draws that would favor some numbers over others are thrown out before they map to your range, so every number has the same chance.
A streak does not change the odds. After three 7s in a row, 7 is exactly as likely as any other number on the next draw.
No repeats
Turn on No repeats until you clear to draw like pulling tickets from a hat. A number that has come up is set aside, and the summary counts how many are left. Changing the range or choosing Clear puts every number back.
Keep a list
Results so far keeps every draw with its range, newest first. Copy history copies the list. The page keeps the latest 1,000 results while it stays open.
