In some software, you can even import diagram templates and plugins to enhance the existing feature set. In these software, you can also find multiple common elements ( Circle, Ellipse, Square, Connectors, etc.) that you can use in your diagram accordingly. To help you out, I have mentioned the steps of sequence diagram creation in the description of each software. You can add and arrange diagram elements over the editing area of these software to complete the diagram. In these software, you can find main sequence diagram elements like Object, Interaction, Fragment, Message, Activation Bar, etc. Most of these software are UML diagram makers that let you create various types of UML diagrams ( Use Case, Class, State, Activity, etc.) including the sequence diagram.

To create a sequence diagram, I have created this list that offers software which provide all necessary tools to design a sequence diagram. It is also a time focused diagram type that shows the order of interaction between objects. A sequence diagram is made to show the interactions between objects or classes in a sequential manner. Here is a list of best free software to create sequence diagram for Windows.
