AWS CloudFormation offers a default stack named CloudFormer, a template creation tool. CloudFormer creates a CloudFormation template from your current AWS environment, allowing you to click which manually created resources to include in your template.
The AWS CloudFormer documentation does not list the AWS services that CloudFormer supports. There is an announcement from 2013 (CloudFormer Now Supports Amazon VPC and More AWS Resources) that lists a subset of supported services, but there is no complete list.
Which services does AWS CloudFormer support? For example, does it support commonly used severless managed services, such as AWS Lambda and AWS Cognito?
