My friends and I love playing BaHotH but the pieces that come with the game are a bit clunky to use. Unfortunately many of the webapps that host the character cards eventually go down because they're personal projects. So I downloaded my favorite incarnation and shoved it in a Docker container that I could host on my site.
Have a look at the demo.
docker build -t me/betrayal .
Everything you need to run the app is inside the container. No persistent storage, no database, no server side scripting.
docker run --rm -d \
--name betrayal \
-p 8080:80 \
me/betrayal
All credit for this app goes to Nolen Tabner which is hosted here.
