Online UML Editor

The tool provides a web-based environment for creating UML diagrams via a concise DSL or diagram primitives. It targets software engineers, architects, teachers, and students who need fast, standards-aligned visuals for design reviews and documentation. Users can model class structures, sequence interactions, use-case scenarios, and activity flows without local software, enabling remote collaboration through a single authoring space.

Diagram rendering is driven by a lightweight UML parser that converts the input DSL into an internal graph model. A heuristic layout algorithm positions shapes and connectors to maximize readability, with consistent spacing and alignment across diagram types. Rendering outputs are vector (SVG) by default and can be exported as raster PNG for inclusion in slides or reports. Validation checks surface syntax errors and structural inconsistencies, guiding revision before export.

The editor is valuable for software teams, educators, and students who need repeatable, standards-conformant visuals. Its core differentiators are simplicity of the DSL, cross-type support (class, sequence, use-case, activity), and easy, dependency-free exports suitable for technical documentation. Use cases include design reviews, API or system documentation, classroom demonstrations, and project artifact creation. The tool emphasizes correctness, clarity, and rapid iteration over feature bloat, making it well-suited for iterative modeling workflows.
