Building the Sendrel Ecosystem

A project log for Sendrel: Offline Terminals for Local Messaging

Sendrel: A LoRa-powered offline terminal for intentional, trust-based messaging without the internet.

When I first began designing Sendrel, I imagined a singular device—a quiet terminal for trust-first, offline messaging. But as the design matured, I realized the strength of Sendrel wasn’t just in its functionality, but in its adaptability.

That realization led me to expand Sendrel into a suite of devices, each shaped by different use cases.

Each form factor shares a common soul: no cloud, no surveillance, no assumptions. Just presence, trust, and consent.

I didn’t want Sendrel to scale like software—I wanted it to echo like stories told in different voices. Different needs call for different tools, but the core values never change.

I still plan to begin with Sendrel Core—formerly the Sendrel Terminal—to deepen my understanding of the system’s behavior before shaping the more complex forms.
