As SaaS becomes a popular aspect of software distribution more and more exciting startups launch their cloud-based productivity applications. Today I stumbled upon “Gliffy” http://www.gliffy.com/. That’s a totally simple, Flash-based dashboard for drawing all kinds of diagrams starting with UML and ending with your office’s floor plan. 30 days trial are free, then you pay $5/month/person. Unfortunately you can’t save any diagrams in trial mode but Gliffy supports exports to other common formats as well – and it has some quite impressive collection of master designs to start with.
