Kombustion
Extend CloudFormation with plugins
Write Native CloudFormation
Kombustion builds upon native CloudFormation, so you don't need to learn a new syntax or DSL.
Extend with Plugins
Kombustion uses plugins to preprocess and extend your CloudFormation templates.
Upgrade Incrementally
Kombustion can be adopted incrementally, instead of requiring a full rewrite of your infrastructure as code.
Decentralised Plugins
Kombustion plugins can be installed from a plugins Github repository.
Cross-Platform
Kombustion works on Linux, FreeBSD and MacOS.
