I don’t use hackernews so just created this account to share, since I thought this was fun and timely.

I’m lucky to have a few tickets to world cup matches this year, and have been wondering who I’ll be likely to see in the knockout stages. So I vibe coded a simulation website with Claude, you can check it out here: worldcupcheerguide.com

You can select which matches you’ll attend, and also add preferences on teams you’d like to see. Then for every match, it will tell you who to cheer for to have the best odds of seeing the best or most exciting teams.

For good measure, I’ve also included a Probabilities tab that shows the most likely teams to end up in every match of the tournament, as well as the most likely matchups.

The whole thing runs in browser and is hosted for free on github pages. The link to the github is on the page. Enjoy!
