This answer is out of date but I can’t delete it because it was accepted. So I’m turning it into a community wiki so that people can fix it up.

Heroku should be gzipping everything automatically (as long as the client supports it of course). From an old blog post:

All apps deployed to Heroku automatically compress pages they serve, by virtue of passing through Nginx’s gzip filter on the way out.

And from the current documentation:

On the heroku.com HTTP stack, requests enter the platform through Nginx, which handles SSL and Gzip.
