CloudFormation Template Generator: Starter AWS YAML in the Browser

Writing CloudFormation from scratch means remembering resource types (AWS::S3::Bucket, AWS::Lambda::Function), intrinsic functions (Ref, GetAtt) and the difference between Parameters and Outputs.

The CloudFormation Template Generator builds a starter YAML template from toggles — S3 with encryption defaults, Lambda wired to an IAM role, optional EC2 and DynamoDB — plus Parameters and Outputs you can extend before deploy.

When to use it

• Spike a stack before moving logic into CDK or SAM
• Learn CFN syntax by reading generated YAML side-by-side with AWS docs
• Copy/paste into PRs as a scaffold for infra reviews

Deploy workflow

1. Toggle the resources you need and set logical IDs
2. Copy the YAML from the tool
3. Review properties (AMI IDs, runtime, bucket names)
4. Deploy with aws cloudformation deploy or your pipeline

Nothing is sent to AWS from the browser — generation is local, like every DevTools utility.
