Analogues of Russian CMS platforms and existing integrations

In short, OneBox's policy on new features and applications is based on just three rules.
For example, there is a question "Will the Weblium application appear in OneBox OS?". Our actions are:
1. If there is a potential client who will become a NEW OneBox OS client if we make a Weblium application, then we do it.
That is, we need +1 (or more) new customers because of this application.
2. If there is an existing client who says "that's it, I won't pay any more rent for the cloud" if you don't have a Weblium app.
Moreover, if this is a small client at the minimum rate, then we would rather let him go and not succumb to blackmail than make an app.
3. If there is a client/lead/partner/anyone and he says "it would be nice to make a weblium app" - then we offer him to invest money and time in the development of this app. As a result, the customer will become the owner of the application with all the consequences:
- he receives money from the sale of this app
- he gets all the questions on this app
- in general, everything is as described https://1b.app/en/partner/how-to-create-app/
And these rules apply to everyone without exception, including even internal employees and customers.
Need some feature or app? Or bring a client to it, or pay for it (it doesn't matter in what proportions and with whom).
