OpenArchFlow is an open-source progressive web app for cloud architects, DevOps engineers, and developers designing AWS infrastructure. Its prompt-based diagram generation and resource import make it relevant to people who want to map AWS designs without starting from a blank canvas. It runs as a hosted web app or a local browser app, and the product is free and MIT-licensed.

The workflow extends beyond drawing. OpenArchFlow imports AWS resources across 24-plus services and infers connections, then lets users export diagrams as Terraform HCL, PNG, or JSON. It can estimate costs using the AWS Pricing API, generate Markdown architecture documentation, and deploy and test diagrams locally with MiniStack. These features suit teams that want a diagram to inform infrastructure work and discussion, rather than serve only as a visual reference. Optional AI backends include Google Gemini, AWS Bedrock, and local WebLLM; integrations also include Google Drive.

The product's scope is a meaningful boundary: AWS is the supported cloud provider, while Azure and GCP discovery are described as future work. Real-time peer-to-peer collaboration uses end-to-end encryption, and optional Google Drive sync offers another way to manage diagrams. With browser storage and community and documentation support, OpenArchFlow is a fit for solo users and small or mid-market teams comfortable with an open-source tool. Teams that require discovery across multiple cloud providers or a different support model should consider alternatives.
