Heroku Ruby Jekyll Buildpack

Heroku Ruby Jekyll Buildpack is a fork of Heroku's official Ruby buildpack with added support for generating static Jekyll sites during the build/deployment stage.

With this buildpack you no longer need pre-build the site or commit the _site build directory to your repo. This simplifies the deployment process and keeps the repo clean. All of the standard Ruby tools are maintained in this buildpack, so you can take full advantage of Rack middleware and other useful tools from the Ruby ecosystem.


Create a new Cedar-stack app with this buildpack

heroku create -s cedar --buildpack

or add this buildpack to your current app

heroku config:add BUILDPACK_URL=

Create a Ruby web app with dependencies managed by Bundler and a Jekyll site. Heroku-Jekyll-Hello-World can be used as a sample starter.
