Gleek is an online tool that lets you start right away.

So instead of scouring through a library of images, you simply type commands into the text box to create your diagram. Rather than using a drag and drop system like Gliffy or Lucidchart, Gleek is entirely text-based.

Gleek is quite different when compared to the other tools on this list. Here are some other features that might attract you to Lucidchart. To get a more in-depth look at what this app can do, check out our side-by-side comparison of Lucidchart with Gliffy.

They offer a wide variety of diagram templates, a full shapes library, and impressive collaboration features. Lucidchart is one of the highest-rated diagramming tools currently on the market. Sequence diagram tools are used by software developers and professionals in other industries to map out systems in a way that’s easy to read and change.

Future system implementation – When updating a preexisting system, a sequence diagram is used, then refined, by analysts to see what is required in order to successfully update a system, or to implement a new one.

Predict object behavior – When designing systems, developers use sequence diagrams to predict how the objects will behave.

See system functionality – Developers can easily see what functions each object performs and when.

So when should you use a sequence diagram? There are several scenarios that are best expressed through this type of visual aid. As you might guess, they express these events in the order of which they occur, in other words, in a sequence. Basically, sequence diagrams track the messages sent between components of a system. Sequence diagrams, also known as ‘event diagrams’, show how different parts of a system interact with each other over time.
