What is the advantage of serverless-rack over using AWS SAM? A quick glance at your project seems like it has a similar general intent, but without the official backing/support of Amazon.
Indeed, SAM and serverless framework serve the same overall purpose. It's mostly a matter of whether you prefer CloudFormation (SAM) or serverless' configuration format. I have mostly used serverless, but there are some posts out there comparing the two in detail, such as: https://sanderknape.com/2018/02/comparing-aws-sam-with-serve...
