Eclipse Mosquitto
The lightweight MQTT broker that connects your devices, from edge to server.
Mosquitto is the Eclipse Foundation's open-source MQTT broker: it routes publish/subscribe messages between sensors, gateways and applications. Written in C, it runs on anything from a microcontroller or Raspberry Pi to a full server, and supports MQTT 3.1, 3.1.1 and 5.0 with TLS. It's the default pick when you want a reliable, minimal broker with no heavy dependencies.

AI-augmented approach, supervised by experts.
We use artificial intelligence as a lever for acceleration and optimisation within our technical processes, while keeping strong human oversight on every strategic phase of the project.
AI improves productivity. It does not replace:
- field experience
- architectural expertise
- understanding business stakes
- technical governance
- complex trade-offs
- cybersecurity
- operational accountability
Beyond visual and technical design, as well as AI-augmented programming, our teams act as a layer of validation, quality control, security hardening and steering, to ensure reliable, scalable deliverables that can operate in real-world environments.
