In their own words
Astah Professional
Astah Professional is a desktop modeling tool for visualizing software design with diagrams and code-related models. It supports UML diagrams, ERD, data flow, flowchart, requirement, CRUD, and mind map diagrams. ER diagrams can be created manually or generated from imported database tables, with SQL export and reverse engineering. Modeling features include automatic layout, traceability maps, project comparison and merging, map view, and state-transition paths and tables. Astah can reverse engineer Java, C#, and C++ and generate code for PHP, SQL, and other languages. Team features cover file locking, file merging, model comparison, and read-only project references; real-time collaboration is not available. Its API and Script Editor can retrieve model information and create or modify diagrams and models. Plug-ins listed include Mermaid, Microsoft Office, Redmine, and Miro. AI Chat Copilot requires an external provider API key or endpoint. Supported platforms listed for Professional 12.0 include Windows 11 x64, macOS 13+ arm64, Ubuntu 24.04, and Rocky Linux 9.6.
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.
