How to serve a static site from Heroku

Conrad Irwin — April 2014

Heroku provides an awesome hosting service for all your apps. But it turns out that you can use it to serve static pages too.

There are a variety of tricks I've seen, but most of them seem to involve complicated hackery, this solution uses ruby's builtin web-server: it's not going to be the most scalable site in the world, but it's more than enough considering that it's totally free :).

Solution

Heroku is controlled by a Procfile, which tells it what to run when your app is deployed. To serve a static site, this is what it should look like:

# ./Procfile

# Use ruby's builtin library tp run an HTTP server
# that listens on $PORT and serves the current directory.
web: ruby -run -e httpd -p $PORT .

And that's it. Just include that Procfile in your git repository then run:

heroku create <name-of-site>
git push heroku master

And your site will be live, you can visit it by running:

heroku open
