In their own words
draw.io
draw.io is a free, open-source diagramming tool for creating visual layouts, from flow charts and mind maps to network, architecture, UML, BPMN and floor-plan diagrams. It supports real-time collaboration, and files can be opened and edited across platforms. Users can choose their own storage or save locally with the desktop app; draw.io says it cannot access users' data. No sign-up or credit card is required to start diagramming, and the desktop app is free forever. Diagrams can remain editable or be exported to SVG, PNG or PDF. Supported imports include draw.io, XML, Gliffy, VSDX, Lucidchart, PNG, SVG and JPEG. Integrations include Google, Microsoft, Atlassian, GitHub, VS Code, Notion and Chrome. Interactive diagrams can be embedded in documents, wikis or applications. The listed platforms are web, Windows, macOS, Linux, iOS and Android. Support is available through GitHub Discussions and Stack Overflow. The site says there is no Enterprise tier for SSO.
Structurizr
Structurizr is a models-as-code tool for creating software architecture diagrams from one C4 model written in Structurizr DSL. A model can produce system landscape, system context, container, component, code, dynamic, deployment, custom, filtered and image views. Its C4 diagrams are interactive and animatable, can be embedded, and include an automatically generated key or legend. Users can work in a browser playground, use a local diagram viewer and layout editor, or run a self-hosted server. The CLI exports workspace views to PlantUML, Mermaid or a static HTML site; supported imports include Structurizr DSL and Structurizr JSON. Version history is available. The product has API, Linux, macOS, self-hosted, web and Windows availability. Structurizr offers a free plan and a 14-day trial. Paid server licenses start at £300/mo (annual) for 1–20 unique users per installation; higher user bands cost more. The self-hosted open core is free when built from source, but has no authentication and public workspaces. Structurizr is headquartered in Jersey, Channel Islands. Its cloud service runs in AWS US-East-1 and describes AES encryption and optional client-side encryption for paid workspaces.
