Ever since we launched the current IP-based solution at $100/month in response to customer demand, we have been pursuing a cheaper and more elegant solution for SSL with custom certificates on Heroku.
Today, we’re happy to announce the public beta of a new SSL add-on that accomplishes this goal. It’s called ssl:hostname, and is priced at $20/month. This new add-on will allow you enable SSL traffic to your application on any subdomain, such as www.mydomain.com or secure.mydomain.com, using your own SSL certificate. Note that this is a paid beta, and you will be charged for using the add-on through the beta period.
