OpenArchFlow

Features

Everything you need to go from idea to production infrastructure.

AI-Driven Design

Describe your infrastructure in plain English. OpenArchFlow's multi-provider AI engine — supporting Google Gemini 2.0/2.5, AWS Bedrock, and local WebLLM — instantly generates interactive architecture diagrams. Refine with follow-up chat: 'Add a CloudFront distribution in front of that S3 bucket.'

  • Google Gemini 2.0 Flash, 2.5 Flash & Pro
  • AWS Bedrock support
  • Local WebLLM (runs in your browser)
  • Incremental diagram modification via chat
  • AI-generated documentation

AI-Driven Design

Infrastructure as Code

Export any diagram to production-ready Terraform HCL. Dependency order is inferred automatically across 60+ AWS resource types — no manual variable wiring required.

  • 60+ AWS resource types supported
  • Automatic dependency inference
  • Production-ready HCL output
  • One-click export

Infrastructure as Code

Local Deployment with MiniStack

Launch a local AWS-compatible environment in under two seconds with MiniStack. Each resource gets an interactive console: browse S3 objects, invoke Lambda functions, inspect DynamoDB tables, and simulate API Gateway traffic.

  • MiniStack integration — 60+ AWS services
  • S3 browser, Lambda invoker, SQS reader
  • Real-time traffic simulation
  • Zero cloud costs for local testing

Local Deployment with MiniStack

Real-Time Collaboration

Work on architecture diagrams with your team in real time. P2P collaboration is end-to-end encrypted — no central server sees your data. Sync diagrams to Google Drive for easy sharing and automatic backup.

  • P2P real-time collaboration
  • End-to-end encryption
  • Google Drive integration
  • No central server or account required

Real-Time Collaboration

AWS Resource Discovery

Connect to your AWS account and import live resources across 24+ services. OpenArchFlow automatically infers connections between resources and renders them as an editable diagram you can immediately export.

  • 24+ AWS services supported
  • Automatic connection inference
  • Import directly to editable diagram
  • Export discovered architecture to Terraform

AWS Resource Discovery

Cost Estimation

See real-time cost estimates as you design. Powered by the AWS Pricing API, every resource addition or removal updates the monthly estimate instantly — before you write a single line of Terraform.

  • Real-time pricing from AWS Pricing API
  • Per-resource cost breakdown
  • Monthly estimate updates instantly
  • Compare architecture variants by cost
