The admin interface is very simple to use, it has all of the features you need built right in without needing any plugins or additional modules installed. I've been able to create sites with different layouts using this one platform. It's easy enough that anyone can pick up quickly but advanced users will be happy too because they get access to more options than others platforms offer. There are some things missing from webiny like contact forms (which we needed) and custom field types which would make our life easier if those were included. We're creating websites around education so having an integrated LMS was something important to us since most schools have their own internal systems already. With webinys' system integration process everything works seamlessly together. As well as being super flexible when building out pages its also pretty quick at rendering them once done editing. Its perfect.
