Haskell on Heroku - BAM Weblog. I've been working on a Yesod webapp over the past few weeks.
I noticed that the skeleton contained a deploy/Procfile. I also know of a couple of developers that have managed to get Haskell running on Heroku. Heroku Cedar is the polyglot platform which allows you to push any binary that will run on their servers. I first tried using Ubuntu 12.04 to compile the binary. Bad mistake; Heroku uses 10.04 so the shared libraries won't match up. Darcs Hosting: Patch-Tag.com. Jgm/gitit - GitHub.
