Zenoh is a Rust-implemented pub/sub/query protocol and library that unifies data in motion, data at rest, and computations with minimal wire overhead (5 bytes). It includes a router daemon (zenohd), multi-language bindings, and support for geo-distributed storages, queries, and queryables from cloud to microcontroller.

Use cases

• publish sensor data from embedded devices to the cloud
• build a distributed pub/sub system for robotics
• query geo-distributed data stores transparently
• communicate between ROS 2 nodes over the network
• stream telemetry with minimal bandwidth overhead
• implement RPC between microservices and edge devices
• bridge enterprise and embedded systems with one protocol

When to choose

• you need pub/sub spanning from microcontrollers to data centers
• you want extremely low wire overhead and latency
• you need location-transparent queries over distributed storages
• you're building ROS 2 or edge computing systems

When to avoid

• you only need a simple message broker like MQTT or RabbitMQ
• your stack is centered on Kafka-style event streaming
• you need a mature ecosystem with extensive third-party tooling
• you require strict license compliance review (dual EPL/Apache licensing)
