Free, Open-Source Manual Diagramming
Draw.io, also known as diagrams.net, is a free, open-source diagramming tool that runs in your browser or as a desktop app. It supports a wide range of diagram types including flowcharts, network diagrams, UML, and architecture diagrams.

Draw.io is a manual diagramming tool where you drag and drop shapes to build diagrams. InfraSketch uses AI to generate architecture diagrams from natural language descriptions, and also creates comprehensive design documents automatically. Draw.io offers more flexibility for general-purpose diagramming, while InfraSketch is purpose-built for system architecture.
It depends on your workflow. If you prefer building diagrams manually with full control over every shape and connection, Draw.io is excellent and completely free. If you want to describe a system in plain English and get a diagram plus a design document in seconds, InfraSketch is the faster option. InfraSketch is especially useful for system design interview preparation.
Yes, Draw.io (diagrams.net) is completely free and open source. There are no premium tiers or paywalls for the core product. The Confluence and Jira integrations have a paid component, but the standalone web and desktop apps are free with no limitations.
There is no direct import for Draw.io files. However, you can recreate any architecture by describing it in InfraSketch using natural language. The AI will generate the diagram, and you can refine it through chat to match your existing design. This approach is often faster than rebuilding manually.
