What I like most about Zen Flowchart is their simple-looking yet powerful user interface. It has most of the tools needed to create extensive flowcharts and most of them are included in the free version. Review collected by and hosted on G2.com.

I think that Zen Flowchart could have more variation regarding the possible charts. It is focused only on flowcharts and they do a good job at it, but sometimes I need to do other type of charts like an entity relationship for example. Review collected by and hosted on G2.com.
