Mike Tigas made a PyPy buildpack for Heroku: http://github.com/mtigas/heroku-buildpack-pypy/ http://github.com/mtigas/heroku-buildpack-pypy/ Here's his blog post about it: http://v3.mike.tig.as/blog/2012/02/13/pypy-on-heroku/ http://v3.mike.tig.as/blog/2012/02/13/pypy-on-heroku/ I haven't used it on a serious project yet, but it was pretty easy to work with.
