Class Diagram Editor

This tool provides a browser-based environment to model software structure as UML class diagrams. It is designed for software engineers, architects, educators, and teams who must communicate domain concepts clearly without writing code. Users define classes, their attributes, operations, and visibility, then assemble relationships to show how components interact. The emphasis is on precise representation, repeatable layouts, and easy sharing across collaborators.
Core capabilities include a data-driven model with required elements (class name, attributes, operations) and relationships (inheritance, association, aggregation, composition, dependency). Optional/advanced features cover package organization, import/export in XMI, live collaboration with version history, and language-agnostic code skeleton generation. The tool enforces UML semantics and validates references to prevent invalid links.
Rendering converts the model into a visual diagram using a robust layout engine that positions elements for readability and consistent edge routing. Outputs are exportable as scalable vector graphics and machine-readable formats. Users can tailor export options, switch between lightweight and detailed layouts, and reuse templates for common architectures. The model acts as a single source of truth for diagrams and documentation.
Typical use cases include design reviews, education, API design, and architecture planning. By focusing on model-driven diagrams rather than decorative visuals, teams gain reliable diagrams, easier version control, and smoother handoffs to implementation or documentation pipelines. The tool differentiates itself through strict model semantics, interoperable exports, and scalable handling of larger diagrams.
