A set of Rust libraries implementing the MQTT standard, including a high-performance broker and an easy-to-use client.
rumqtt is an open-source set of libraries written in Rust that implements the MQTT protocol, providing both a high-performance broker and an easy-to-use client. It solves the need for reliable, efficient messaging in IoT and real-time systems by offering a robust, embeddable MQTT ecosystem.
Developers and engineers building IoT applications, real-time messaging systems, or embedded devices that require MQTT communication, particularly those working in Rust ecosystems.
Developers choose rumqtt for its performance, simplicity, and robustness in implementing MQTT standards, along with the safety and concurrency benefits of Rust, making it a reliable choice for critical messaging infrastructure.

rumqttd is designed for performance with support for MQTT 3.1.1, QoS 0-2, and TLS, making it suitable for demanding IoT applications as highlighted in the README.
Offers multiple installation methods including Docker, Cargo, prebuilt binaries, and AUR, simplifying setup and self-hosting as detailed in the installation section.
rumqttc provides a high-level, easy-to-use MQTT client with support for both MQTT 3.1.1 and MQTT 5, reducing development overhead for Rust-based messaging systems.
The rumqttd broker explicitly lacks MQTT 5 implementation per the features list, limiting its use for applications needing modern protocol features like shared subscriptions or user properties.
Compared to mature MQTT solutions like Mosquitto, rumqtt has fewer plugins, monitoring tools, or community integrations, which may require custom development for advanced use cases.
While the client is easy to use, the broker and libraries are Rust-focused, so non-Rust teams may face integration challenges or a steeper learning curve for embedding or extending functionality.
