*The Serverless Framework and AWS SAM support other runtimes and providers with various degrees of functionality. The Serverless Framework best supports AWS and Node.js or Python Lambda functions, but it remains a good tool for many different runtimes. AWS SAM similarly supports several different runtimes. Both frameworks also have options for building custom runtimes and more recently support for brining your own containers.

**Both AWS Amplify and the Serverless Framework have open source and commercial components. And they both require you to pay for services on a cloud provider like AWS. The Serverless Framework has MIT-licensed code for the Framework itself and an optional proprietary platform. AWS Amplify has Apache 2.0 licensed code and integrations with the proprietary parts of the AWS cloud.
