jBackend Community
jBackend Community is the lite version of jBackend available for free, no subscription required. It provides all the basic features to integrate Joomla content with mobile apps, syndication networks, affiliate networks and any external system, and it is mainly intended to give a chance to test jBackend capabilities, to develop and test new modules, and to provide some basic REST API integration features to a Joomla site.
When the upgrade to the full jBackend version is required, it is possible to install the full jBackend package over the Community version. The two versions share the same data tables and settings, and the upgrade process will preserve the configuration and all existing data.
The Community version is completely free, but doesn't provide the full functionalities available for jBackend. Here's a comparison matrix between jBackend Community and jBackend:
