Tool
SequenceDiagram.org
Focused sequence diagram editor with text syntax.
About
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.
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 raise a request in our Help Center or send email to info@sequencediagram.org . The more feedback we get the better we can prioritize.
No license is imposed by SequenceDiagram.org on the generated output. However, like with all images containing text, the fonts used might. The default font used in diagrams is the default sans-serif font selected by your browser. You can specify a different font using the fontfamily keyword, see help for more information.
