Open source insulin delivery systems are gaining popularity for their ability to give people with diabetes more control, customization, and flexibility in their care. These systems, including Loop, Trio, and AAPS, are open-source and community-driven, meaning they’re not backed by traditional medical companies but instead by passionate developers and diabetes advocates who want more out of their treatment.

Unlike FDA-approved insulin delivery systems, which are often constrained by regulatory standards, open source systems offer advanced features that allow users to personalize every aspect of their insulin delivery. From caregiver controls and remote bolus to Siri Shortcuts and geofencing, these systems go beyond the basics to offer cutting-edge functionalities that most commercial systems lack.

For instance, Loop, one of the most popular systems, integrates with Dexcom sensors and the Omnipod DASH pump to create a closed-loop system. It adjusts basal insulin delivery and auto-correction boluses based on real-time glucose levels, with the ability to set profiles, and even build custom overrides for exercise and illness.

Trio, another innovative system, combines the same open-source principles but integrates features like Unannounced Meal detection, super micro boluses (SMBs), and Dynamic ISF (insulin sensitivity factor) for even tighter control and adaptability. AAPS (Android APS) runs on the same algorithm as Trio, O-ref1 and is compatible with Android phones.

Setting up and maintaining these systems isn’t for everyone. It requires some understanding of technology, and without a dedicated support team, troubleshooting can be challenging. That said, there are Facebook groups and Discord channels dedicated to help one another.

If you’re interested in learning more about these DIY systems and which one might be the best fit for your needs, our latest podcast breaks it all down. Tune in to the video below or listen at the top for a deeper dive into how these open-source AID systems work and how they stack up against FDA-approved systems.
