Diagram as Code.

Diagrams lets you draw the cloud system architecture in Python code. It was born for prototyping a new system architecture design without any design tools. You can also describe or visualize the existing system architecture as well. Diagrams currently supports six major providers: AWS, Azure, GCP, Kubernetes, Alibaba Cloud and Oracle Cloud. It now also supports On-Premise nodes.

Diagram as Code also allows you to track the architecture diagram changes in any version control system.

NOTE: It does not control any actual cloud resources nor does it generate cloud formation or terraform code. It is just for drawing the cloud system architecture diagrams.

It requires Python 3.6 or higher, check your Python version first.

It uses Graphviz to render the diagram, so you need to install Graphviz to use diagrams. After installing graphviz (or already have it), install the diagrams.

macOS users can download the Graphviz via brew install graphviz if you're using Homebrew.

# using pip (pip3)
$ pip install diagrams

# using pipenv
$ pipenv install diagrams

# using poetry
$ poetry add diagrams

You can start with quick start. Check out guides for more details, and you can find all available nodes list in here.

Let me know if you are using diagrams! I'll add you in showcase page. (I'm working on it!) :)

GitPitch is a markdown presentation service for developers. Diagrams is now integrated as Cloud Diagram Widget of GitPitch, so you can use the Diagrams when to create slide decks for Tech Conferences, Meetups, and Training with GitPitch.
