I have a habit of buying domains before I know what I'm going to use them for. Sinatra park is a very simple Sinatra script that makes it easy to park them on Heroku until they find a purpose.
- Grab the code
- Create a Heroku app
- Push to Heroku
- Get the Custom Domains addon and add the domains you want to park
- Point the domains at
proxy.heroku.com
default.erb is the page that visitors to the domain will see. You can also add different pages for different domains, such as example.com.erb.
