Sinatra is one of our favorite frameworks at Heroku. Many of our apps use Sinatra, and Blake even works here. All this means we’re extremely excited to congratulate the Sinatra team on the 1.0 release!
You can use Sinatra 1.0 today on Heroku. It works with both the Aspen and Bamboo stacks. Simply add the gem to your .gems file, git push, and you’ll be running Sinatra 1.0!
