Ranked in these QuestionsQuestion Ranking
Pro Good for mobile app development companies
Scales very well and useful console to view all their apps and its fully rebrandable which works great if you want to give the clients you are building apps for access to their own view of how it is performing. The fact that it comes with integrated push notifications and their automated monthly report is also great.

For companies or large teams of developers, where there are multiple projects being worked on at once, you can choose permissions for any developer and decide who gains access to each app on the backend.
Lets you rebrand the system, which works well if you want to give the clients you are building the app for access to their own view of how their app is performing.
Also like the fact it comes with the option of integrated push notifications and an automated executive summary report.

Pro Open Source
Kuzzle is open source and it's released under the Apache 2 License.
Pro Realtime through filters
You do not connect to classic rooms but to search filters and can be warned of changes on permanent storage or volatile one.
Con Weak documentation
Kumulos is lacking in the documentation department. A lot of things are explained in just a few sentences, with many things even being absent entirely.
In the last year they launched a dedicated Docs site that has made this a lot better.
Con No hosted version
Kuzzle has no hosted version. In order to use it, you have to install it to a remote machine. This can be cost-effective but it also adds overhead because you will have to take care of the hosting and backend infrastructure yourself.
Con May have issues since it's stil la relatively young project
Kuzzle is (as of February 2nd, 2015) in alpha version and approaching beta.
