Hosted broker included
MQTT sensors to live dashboard in two minutes
Point your devices at the built-in broker — or bring your own — drop in widgets, and watch live data flow. Then automate what happens next. No code, no YAML, no servers.
Free plan · No credit card · Any MQTT 3.1.1 / 5.0 broker
[ 01 — How it works ]
Three steps. No code.
01
Create a project
Each project gets its own broker connection, topics, and dashboard — one per greenhouse, rig, or site.
02
Point your devices
Use the hosted broker that comes with the project (zero setup), or plug in your own Mosquitto, HiveMQ, or EMQX.
03
Drop in widgets
Values, charts, buttons, setpoints. They go live the moment the first message lands — no polling, no refresh.
Built where conditions matter
[ 02 — Automation ]
Most dashboards watch. Yours acts.
Rules watch your topics around the clock and act on thresholds — switch relays, open valves, ping you on Telegram. Monitoring is free forever; when you're ready to close the loop, that's Pro.
- Threshold rules on any topic — above, below, equals, changed
- Relay & setpoint control — publish back to your devices
- Telegram alerts, straight to the phone in your pocket
Rule 01 — fruiting room
WHEN greenhouse/zone-1/co2 > 1200 ppm
THEN relay/exhaust-fan → ON
STATUS: ARMED · fired 3× today
Rule 02 — heat watch
WHEN grow/tent-2/temp < 18.0 °C
THEN telegram → “Heat failed in tent 2”
STATUS: ARMED · last fired 02:14

[ 03 — The essentials ]
Everything live. Nothing to babysit.
F/01
Live by default
Widgets update over server-sent events the moment a message lands. No polling, no refresh button.
F/02
Any broker — or ours
Mosquitto, HiveMQ, EMQX, or the hosted broker that comes with every project.
F/03
Share the proof
Every dashboard gets a read-only public link. Anyone can watch live — no account needed.
F/04
History that holds up
Charts are backed by stored samples — 7 days on Free, 90 days on Pro.
F/05
Retained-state aware
Boards load with your devices' retained values, not blank tiles. PLC and HMI friendly.
F/06
Widgets that write
Buttons and numeric setpoints publish back: toggle relays, set target temps, tune fan speeds.

[ 04 — Agent-ready ]
Your AI agent can build the whole thing
MQTT Studio speaks MCP. Hand Claude — or any MCP-compatible agent — an API key and it can create projects, lay out widgets, and wire up automation rules while you watch them appear live.

Frequently asked questions
What is MQTT Studio?
MQTT Studio is a no-code tool for turning live MQTT data into dashboards you can build and share. You connect any MQTT broker, pick the topics you care about, and add widgets that update in real time.
What is MQTT?
MQTT is a lightweight messaging protocol widely used by IoT devices and sensors. Devices publish data to topics on an MQTT broker, and clients subscribe to those topics to receive updates in real time.
Which MQTT brokers does it work with?
Any broker that speaks MQTT 3.1.1 or 5.0, including Mosquitto, HiveMQ, and EMQX. You can connect your own broker, or use the hosted MQTT Studio broker.
Do I need to write any code?
No. You set up your broker connection, topics, and widgets entirely from the browser. There are no config files, no YAML, and no deploy step.
Can my dashboard react to the data, not just display it?
Yes. Automation rules watch your topics and act on thresholds: switch a relay when CO2 gets too high, or send a Telegram alert when temperature drops. Rules and alerts are part of the Pro plan.
Can AI agents use MQTT Studio?
Yes. MQTT Studio has a remote MCP server and personal API keys, so Claude and other MCP-compatible agents can create projects, add widgets, and manage automation rules for you. Everything an agent builds shows up live in your dashboard.
Can I share my dashboard?
Yes. Every dashboard has a read-only share link you can send to anyone. Viewers see live data without needing an account.
Is MQTT Studio free?
Yes. The free plan lets you monitor one project with live dashboard widgets and a shareable public dashboard. The $9.99/mo Pro plan unlocks automation rules, Telegram alerts, and relay control, plus more projects and longer history.
