This is a collection of extensions that I've curated in this vscode extension pack to help you build, deploy and manage your AWS CloudFormation templates.
[!TIP]
Catch AWS waste before and after you deploy.
CloudBurn is a free, open-source CLI that checks your Terraform and CloudFormation for costly patterns before deploy, then finds the waste already running in your AWS account. Run it locally or in CI.

Want it managed across your AWS accounts? CloudBurn Platform runs it for you and keeps scan results in your own account. Join the waitlist for 30% off.
