From your
repo.
A real
diagram.

Paste a GitHub URL. Archway scans the codebase, identifies systems and their internal containers, and produces a multi-system C4 container diagram in seconds. External SaaS dependencies surface as standalone systems only when the scan finds evidence. No decorative empty boxes.

Point at a schema.prisma, Drizzle schema, or SQL DDL file in your repo. Archway parses the schema directly into an Entity Relationship Diagram in under a second: no AI call, no hallucination risk, no quota cost. The schema is the model.

Right-click any service node to swap it across providers: AWS RDS to Aurora to GCP Cloud SQL to Azure SQL Database. The underlying canonical architecture model and the rendered diagram update together. What-if exploration without rebuilding the diagram.

Describe your architecture in plain English. Our AI understands system design patterns and generates accurate, production-ready diagrams, not toy examples.

Cloud architecture, sequence diagrams, ERD, data flow, flowchart, C4 model, and network topology. All generated from a single description. Zero context switching.

Export to Mermaid, PlantUML, D2, Draw.io XML, SVG, or PNG. Your diagrams work in every tool your team already uses.

Edit diagrams together with your team simultaneously, with CRDT-powered sync and zero conflicts. Attach markdown notes alongside each diagram for architecture decisions, trade-offs, and context.

Deploy on your own infrastructure. Your data stays within your network. Docker Compose for a single-command deployment.
