SequenceDiagram.org is a completely free online tool for creating sequence diagrams.
There are many sequence diagram tools out there but this is the only one which allows you to:
In other words bringing the best from both worlds. This makes it very easy to work with large diagram where other similar tools struggle. It also doesn't have any ads or unnecessary distracting elements. (Even the top bar can be hidden to maximize the working area)
The tool is developed and maintained by people who create a lot of sequence diagrams in their daily work and from efficiency point of view weren't 100% satisfied with the existing tools. The graphic design is created by yusi.se.

Are diagrams stored in any way or sent to any server by SequenceDiagram.org?
No, all parsing and drawing of diagrams is executed solely on the client side in your browser. (In the past, the share URL button used a query parameter to transport the diagram data, which meant that the data in the URL was visible in the http access logs when someone used the generated URL. This is no longer the case since fragment '#' is used instead which is dereferenced solely by the user agent, see https://tools.ietf.org/html/rfc3986#section-3.5
Are diagrams/scripts created using SequenceDiagram.org covered by any license?
No license is imposed by SequenceDiagram.org itself. However, like with all images containing text, the font you chose to use might, depending on how you plan to use the image. 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.
