As of October 18th, 2017, our paid subscriptions for MageBridge are no longer available. If you want to use MageBridge for Magento 1, you can. Just browse to GitHub and use the sources as you see fit - they work fine with Magento 1 and Joomla 3. We have multiple reasons for this drastic change.
We hope you understand our point of view and therefore, our decision - how tough as it might seem.
We have stated in the past that MageBridge will support Magento 2 partially. This is no longer true: It would be too much work for a business need too small. MageBridge will therefore cease to exist, once Magento 1 is definitely obsolete.
