Web UML Tool

The Web UML Tool is a browser-based modeling environment that focuses on software architecture diagrams used in web applications. It supports class diagrams, sequence diagrams, use case diagrams, and activity diagrams. Users create diagram models within a project workspace, with version history and per-project access controls. It is intended for software engineers, architects, product managers, and development teams who need to design, validate, and communicate architectures early in the lifecycle.
Conceptually, users define diagram elements (classes, actors, lifelines) and relationships (associations, inheritances, messages). The tool validates UML syntax, offers auto-layout, and supports exports to SVG, PNG, PlantUML, and Mermaid. It also accepts textual imports and can generate code skeletons from models.
Audience includes software engineers, system architects, product managers, and DevOps teams designing APIs and microservices. The tool's unique value lies in cloud-based collaboration, template repositories (MVC, layered architecture), and integration hooks for CI/CD, issue trackers, and repository links.
Core features include diagram templates, element property editors, lightweight constraints, live collaboration, versioning, review comments, and export options. Typical use cases include API design diagrams, database schema planning, and deployment architecture.
