Broker-enforced Protobuf schemas shrink payloads 4x, runs in 2.6 MB with service discovery baked in.

Strengths

•Custom Protobuf engine written from scratch in Zig—not wrapping an external library
•Service discovery eliminates pre-sharing .proto files; clients download schemas on demand
•Concrete payload math (310 bytes JSON → 82 bytes Protobuf) proves real bandwidth wins for cellular IoT

Weaknesses

•Audience is niche: requires IoT use case + willingness to adopt schema layer over plain MQTT
•Early-stage project (18 stars); ecosystem maturity and library support unproven vs. Mosquitto
