MQTT brokers online with a free offer to test and connect IoT to the internet

MQTT broker with free online offer
Table of Contents

A selection of free MQTT brokers available online for testing. An online broker will be useful for testing communication outside the local network during the development of connected objects or the development of a home automation installation.

 

Online MQTT brokers (including 5 with a free offer)

In 2020, the MQTT protocol is very widespread. Several platforms have bowed out. The best known is undoubtedly ThingStudio which offered a completely free offer for Makers, Hackers and Designers: cry: MQTT.io and ThingMQ also disappear.

Fortunately, nature does not like emptiness, new entrants try their luck on the market.

Like Cayenne, the MQTT protocol has enabled manufacturers to offer new services and to be less dependent on the sale of equipment that is highly competitive with Asian cloners. This is for example the case of Adafruit with its AdafruitIO platform. The free offers are obviously limited, in number of accessories, bandwidth, etc … but it is more than enough for testing and even for personal use.

For personal projects or a startup that wants to test an idea, cloudMQTT and Flepsi remain two sure values. The free offer covers most needs and the advantage of being able to migrate to a robust professional offer.

A special note to Flepsi which also offers the sending of 10 free SMS per month.

MoQiatto is a completely free project developed by Çagdas Döner which uses the services (for a fee) from Amazon AWS to operate. Do not hesitate to support the project in front of Patreon of this Broker from 3.3 €/month. Several integration examples are available on GitHub. MoQiatto supports TLS / SSL security.
