The add-on is a new version of the open source project originally created by Mike Heffner (https://github.com/mheffner) and we've taken it over with his blessing. The new version is also open source, see: https://github.com/getstrake/aws-pricing-sheets-addon
This is a soft launch and we'd love some feedback. Our goal is to support more AWS services soon and more clouds in the future. We hope it makes life just a little bit easier when tackling your cloud spend.
