Lucidchart vs Structurizr

Lucidchart is a web, iOS, and Android diagramming tool with real-time collaboration and offline editing. It supports process maps, flowcharts, organizational charts, technical and system architecture diagrams, UML diagrams, ERDs, sequence diagrams, Gantt charts, and C4 models. Users can import VSDX, VSD, VDX, Draw.io XML, OmniGraffle flat files, BPMN, and XPDL, then export PDF, PNG, JPEG, SVG, VDX, VSDX, JSON, or CSV. AI can create diagram content from text prompts, and UML markup can generate sequence diagrams from text. Google Sheets, Excel, and CSV data can link to visualizations; conditional formatting highlights patterns, while layers manage visibility and hierarchy. Lucidchart offers more than 100 custom-built integrations and a free signup. The Free plan costs nothing for Basic diagramming access. Individual, Team, and Enterprise plans are listed without prices. Lucidchart is associated with Lucid Software Inc., founded in 2010 and headquartered in South Jordan, Utah.

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.
