14 of the Best IoT Platforms to Watch in 2021

1

ThingWorx

From developing your first prototype to building a full-fledged IIoT-scale solution, ThingWorx by PTC is one of the most popular IoT platforms. Its biggest advantage is that all the hard work and programming is confined to the back-end: the front-end users needn’t bother about device connections or individual device status. A drag-and-drop editor alone creates your application interfaces. Supporting a low-code programming environment, ThingWorx contains a fairly large library of extensions and widgets with applications in multiple industries.

Adafruit IO

Adafruit IO is an IoT platform offering from the same company which manufactures Adafruit Feather boards, one of its example applications which we covered is regards building web servers. The platform supports hardware of many makers including Raspberry Pi, ESP8266, BeagleBone, and is well-supported on Arduino IDE. On the developer end, all user interface actions are executed in its single API (shown below). It contains the client libraries, data, webhooks, triggers, users, and tokens. Adafruit IO is free to use for beginners and prototype developers with some limitations in data points, data storage, and triggers for a given time.
