Make a tournament bracket in the style of any Production Studio layout: single or double elimination, Swiss or groups. Type scores and winners move on by themselves. Pull it in from Challonge, share a live link, save a picture for socials, or download it as one HTML file you can keep editing and drop into OBS.
Teams come in by seed and every finished match is placed by its two teams. The key is used for this one request and is never kept.
Everything here is saved in this browser as you go.
The HTML file is the whole bracket in one file with its own Edit button, so you can keep changing it without this site. In OBS add a Browser Source, tick Local file, pick the file, 1920 x 1080. The PNG uses the size picked in Look.
A link anyone can open to watch the bracket. It updates a few seconds after every change you make here.
A downloaded HTML file made while the link is on can follow it too, so OBS shows results typed here.
