It keeps a results history, has a full screen view and autosaves to your browser.

The free part: The wheel, elimination mode, digits mode, history and 15 saved files are free. Premium adds your own sounds, colours, logo and background.

The Premium price is not shown on the page we read.

• Best for a draw you want to call truly random, or very long lists
• Free plan, paid upgrades

The best-known source of randomness on the web: its numbers come from atmospheric noise rather than a formula. The Integer Generator makes up to 10,000 numbers at a time within plus or minus one billion, and its Sequence Generator shuffles a range with no duplicates. The site's cookie notice says it carries no ads and will never sell your data to third parties.

The free part: The site's FAQ refers to a free daily allowance of random bits, and its home page labels many tools as free services.

Per its FAQ, extra allowance and the Premium Generator for lists over 10,000 items are paid, and the Third-Party Draw Service needs at least $4.95 of prepaid credit (as of 2026-10-29).

Watch for It is a form, not a big-screen display, so the number is small on a projector, and no-repeat draws live on a separate Sequence page. Your request is made on its servers and a daily quota applies.

The panel is free and needs no sign-in.
