The simplicity of creating new rules for tasks/workflows from scratch is great! And it supports all major rule languages (XPath, Json). So you do not need additional extensions or plugins. Rules could be configured by non technical users. There are also no limitations regarding number of input parameters, which makes writing complex logic much easier than using existing solutions like Workflow Engine. I would say UI looks outdated compared to other tools out there but maybe this is just my opinion. This tool has been helping us automate repetitive tasks in very short timeframes. It enables business stakeholders to easily configure workflows without having any coding skills required.
