MQTT Development Services
MQTT development services for real-time IoT — broker architecture, secure TLS/mTLS device fleets, QoS design and message pipelines that actually scale.
What mqtt development with CodeCaracal includes
MQTT is the messaging backbone of most IoT systems — and the difference between a broker that works for ten devices and one that survives ten thousand is architecture. Topic design, QoS levels, retained messages, mTLS identity and back-pressure all matter long before the first device connects.
We build and fix MQTT systems for production: broker selection and sizing (AWS IoT Core, EMQX, Mosquitto or VerneMQ), secure device onboarding with per-device certificates, topic and QoS design, bridges into databases and message queues, and load testing so you know where the breaking point actually is.
What we deliver in an MQTT project
Types of projects we support
MQTT Development covers more than one shape of project. These are the engagements we take on most often.
Broker architecture and setup
Sizing, securing and tuning an MQTT broker for your device count and budget.
Device fleet onboarding
Certificate-based identity so every device authenticates and only reaches its own topics.
MQTT-to-dashboard pipelines
Sub-second telemetry from broker to live dashboards via WebSocket and time-series storage.
System integration
Bridging MQTT into Kafka, databases or your existing backend with reliable delivery.
Legacy MQTT rescue
Auditing an existing broker setup for security holes, message storms and scaling limits.

Frequently asked questions
Practical answers to the questions clients ask before starting a mqtt development project.
Which MQTT broker do you recommend?+
AWS IoT Core when you are already on AWS and want managed device identity; EMQX or VerneMQ when you need self-hosted scale and multi-tenancy; Mosquitto for small internal deployments. We size it to your device count and budget.
Is MQTT secure enough for production?+
Yes, when done right: TLS in transit, unique certificates per device, least-privilege topic policies and signed updates. We harden all of these by default.
We already have devices publishing to a broker. Can you build the backend on top?+
Absolutely — we ingest from your existing broker, build the processing pipeline, and deliver the dashboards, alerts and APIs on top.
How many devices can an MQTT broker handle?+
A well-architected single broker can handle tens of thousands of connections, and clustered brokers (EMQX, VerneMQ) scale well beyond that. The bottleneck is usually message throughput and persistence design, not raw connections — which is exactly what we load-test before you commit to an architecture.
What is the difference between MQTT and WebSocket for real-time data?+
MQTT is a publish/subscribe protocol designed for constrained devices and low-bandwidth links; WebSocket is a browser-friendly full-duplex channel. Most of our systems use MQTT device-to-broker and WebSocket broker-to-browser, so the dashboard gets sub-second updates without polling.
