cfn-builder[0] is my take on simplifying CloudFormation templates and allowing project teams to manage their own stack. I built it specifically to use in a CD/CI environment so it doesn't use things like input parameters that might change from one run to another. Most variables are stored either in a global namespace (AccountId, IP Addresses, AMIs, etc.) or in separate environment namespaces (Subnet IDs, CidrBlocks, etc.) It even includes several built-in commands to help you maintain your environment, including one to update the global namespace with current AMI information.

The CFN coverage is not as complete as I would like but I've built and managed production workloads with it and it does the job. Since it's built on NodeJS so if you know JSON and a little bit of Mustache it's not hard to understand. Anyone want to help?
