Version v0.14 of Metabase is no longer supported. Check out the docs for the current stable version, Metabase v0.63.
Metabase is currently offering beta support for Heroku deployments and planning to improve support for Heroku going forward. Metabase will deploy and run fine on Heroku but there are a few limitations.
Before doing anything you should make sure you have a Heroku account that you can access.
If you’ve got a Heroku account then all there is to do is follow this one-click deployment button
This will launch a Heroku deployment using a github repository that Metabase maintains.
Now that you’ve installed Metabase, it’s time to set it up and connect it to your database.
