Free tool
Random draws nobody can rig
Giveaway winners, raffle numbers, team picks. Each draw is bound to a public randomness beacon, so the result does not exist until the beacon lands, and anyone who opens your result link can re-check it in their own browser. No account. Nothing stored.
What you get
- A result link that carries the whole proof. Open it anywhere and the checks re-run in the browser.
- Winners in draw order, so first prize is first.
- For announced draws, a commitment link to post before the result exists.
- A proof file to keep, and an API and library to do all of this from code.
- Every result opens on the result page, where the checks run again for whoever is looking.
What it costs
Nothing. No account, no limits worth mentioning, no data kept. The tool is open source under the MIT licence. BetTip earns from the rest of this site, not from this page. Pricing, in full.
