Backendless offers three billing plans to choose from – Free, Cloud9 and Cloud99. You can see the details of all the plan on the Backendless Cloud Pricing page. Each plan has its own limits which can be be increased/customized for the Cloud9/99 plans. A plan customization is done via a purchase of a “Function Pack” from our Marketplace. For example, take the Cloud9 plan. The plan offers up to 3 custom security roles. The number of roles created in an app on that plan can be increased to be unlimited with a purchase of the “Unlimited custom roles” function pack ($20/month). Likewise, all other limits in that plan (or in the Cloud99 plan) can be increased or removed.
