Ilograph vs Structurizr

Ilograph creates interactive visual documentation for systems and the ways their components interact. Users can zoom between detailed and broad views, switch perspectives, and use sequence perspectives to show data, business and security flows. Its model-based diagrams-as-code approach adds structure and supports consistency and reuse. Diagrams can be navigated by keyboard and are designed for screen readers; environments include AWS, Azure, GCP and networking icons. Ilograph Desktop runs on Mac, Windows and Linux, and works with local files without internet access for offline or high-security environments. The Export API runs in an on-premises Docker container without external internet access and produces standalone HTML files. Its Confluence Cloud app stores diagrams in the Confluence instance and does not require an Ilograph account. The free plan includes unlimited public and private diagrams, unlimited diagram size and 14 days of history. Listed paid options include Pro at $18.00 per month billed yearly, Team at $30.00 per month billed monthly, and Desktop at $14.99 per month billed monthly.

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.
