Sequence Diagram Editor

Finding a Free Sequence Diagram Tool?

Free web-baed UML drawing tool – Visual Paradigm Online (VP Online) Free Edition. Unlike many other online drawing tools, VP Online has incorporated the Resource Centric interface, which makes Sequence Diagram editing very intuitive and straight forward. The free UML editor comes with no ad, no limited period of access and no limitations such as, number of diagrams, number of shapes and etc. You own the diagrams you created for personal and non-commercial purposes.

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 tool to familiarize yourself and find different ways you can use sequence diagrams to map out your technical process and infrastructure.

If you’re new to UML altogether, use our guide to answer questions such as “What is UML?” and “How can I use it?” Once you’re prepared with a diagramming program like Lucidchart, it’s time to start drawing.

Within GenMyModel, you can create your sequence diagram online, share and export images. Everything is handled in your web-browser with an intuitive user interface. The sequence diagrams conform the UML2 standard. You get both a visual representation, called the diagram, and the internal structure of your model in a tree-based representation. It works on Windows, Mac, Linux and the supported browsers are IE, Chrome, Firefox, Safari and Opera.

Unified Modeling Language

A sequence diagram in the Unified Modeling Language (UML) is an interaction diagram that shows how processes operate with one another and in what order. UML sequence diagrams model the flow of logic within your system in a visual manner, enabling you both to document and validate your logic, and are commonly used for both analysis and design purposes. Sequence diagrams are the most popular UML artifact for dynamic modeling, which focuses on identifying the behavior within your system.

The sequence diagram is a construct of a message sequence chart. A sequence diagram shows object interactions arranged in time sequence. It depicts the objects and classes involved in the scenario and the sequence of messages exchanged between the objects needed to carry out the functionality of the scenario. Sequence diagrams are typically associated with use case realizations.

A sequence diagram shows, as parallel vertical lines (lifelines), different processes or objects that live simultaneously, and, as horizontal arrows, the messages exchanged between them, in the order in which they occur. This allows the specification of simple runtime scenarios in a graphical manner.

Sequence diagrams are typically used to model usage scenarios, the logic of methods and the logic of services.
