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
