SequenceDiagram.org is an online tool / software for creating UML sequence diagrams. Founded in 2014 with the purpose to improve the efficiency when creating and working with sequence diagrams by combining text notation scripting and drawing by clicking and dragging in the same model.
All parsing, processing, and drawing is done client side. The benefit of this is that SequenceDiagram.org is fast and convenient to work with; it also doesn’t transfer your diagram data over the Internet like many other sequence diagram tools on the market. This also means that it is possible to work with the tool offline.
Sequence diagram. Popular beyond just the design community, this visually appealing diagram is good at showing all types of business processes. It simply reveals the structure of a system, showing the sequence of messages and interactions between actors and objects chronologically. Sequence diagrams show simple iteration and branching. A timing diagram is a type of behavioral or interaction UML diagram that focuses on processes that take place during a specific period of time. They're a special instance of a sequence diagram, except time is shown to increase from left to right instead of top down. Sequence diagrams map out complex architecture, but they can be surprisingly easy to create. Sequence diagrams are a popular subset to UML, so if you’re new to the topic, use our sequence diagram tutorial to familiarize yourself and find different ways you can use sequence diagrams to map out your technical process and infrastructure.
The tool is developed, maintained, and used by people who create a lot of sequence diagrams in their daily work. If you have any question / comments / suggestions / bugs please contact [email protected]. The more feedback we get the better we can prioritize.
