A random name picker you can prove was fair.
Paste names, handles or emails. Drawproof locks the list, has two independent authorities timestamp it, and picks winners with public randomness that didn't exist yet. Share the proof link and let anyone check.
Free during the beta. No sign-up, for you or for the people on the list.

For draws where someone will ask how the winner was picked.
Prize draws for customers or followers, door prizes, community picks, sign-up lists with more names than spots. Anywhere a screenshot of a spinning wheel isn't enough.
Paste the list
One name per line, or upload a CSV and pick the column. Repeats are merged, or counted as extra entries if your rules say so.
Choose the winners
Up to 100 winners and 50 backups, drawn in order in case a winner doesn't respond.
Lock and draw
The list is fingerprinted and timestamped, then public randomness picks the winners about a minute later.
Share the proof
Everyone on the list can check their name was in and re-run the draw in their browser.

Questions
Is it really random?
Yes. The winners come from a drand randomness round published by the League of Entropy after your list was locked, turned into picks with SHA-256 and rejection sampling so no name is favoured. Here's exactly how it works.
Are the names published?
No. The list is published only as salted fingerprints. Winners are shown by name, with email addresses masked, and anyone who knows a name can check whether it was in the list.
How many names can I use?
Up to 25,000 different names per draw, pasted or uploaded as a CSV.
Can I undo a draw?
You can cancel from your private manage link until the randomness round, about a minute after locking. The cancellation is shown on the proof page. After that the result is final.
Is it free?
Yes, every feature is free during the beta.
