I like that we have more control over our data than other solutions out there, which is important since it's in an EU country! The customer support could be better from time to time when you are not able to reach someone by phone or email at least within 24 hours (we were waiting 3 weeks before reaching anyone).
You can't get your own domain if using this platform, so make sure to know what you need first - do research about best practices regarding hosting platforms used together with this product. We use codekeeper because they offer us many benefits compared to others services available online. This includes being able to store multiple versions of files that we send to customers along with licenses & contracts signed between them, making backups easy and simple without having any additional costs involved.
