Sequence diagrams can be a critical tool to designing and understanding any software engineering project.

websequencediagrams.com is free, easy-to-use, and always-available. It can output as PDF, and there are currently nine different visual styles to choose from ("napkin" style shown above).

My favorite part is that you can create your sequence diagrams by coding them, instead of fussing with a horrible, bloated, frustrating, mouse-driven tool like Visio.

There's even an API websequencediagrams.com/embedding AND a self-hosted option websequencediagrams.com/order

Know of a better tool? Know of any similar tools for other types of UML diagrams? Share below!
