Why Trust Techopedia

Key Takeaways:

  • Explore top 5 free IoT platforms for effective IoT device management, data collection, visualization, and analysis.
  • Start your IoT project with a free trial plan or build your IoT solution with a 100%-free open-source IoT platform.

As the demand for Internet of Things (IoT) platforms increases, so do the prices of these platforms, making it difficult for companies to decide what IoT solution will work best for their business.

However, a number of free IoT platforms could be a viable option for companies initiating their IoT projects, offering them a testing ground before investing in a more comprehensive custom IoT software solution or committing to a particular platform-based paid IoT service.

Typically, premium paid plans with advanced features are more appropriate for extensive commercial use. However, some open-source IoT platforms are also free for commercial use but charge for support.

Open-source free IoT platforms have the same core capabilities as other Internet of Things software, connecting, managing, monitoring, and controlling IoT devices, as well as providing comprehensive IoT data analytics functionality. IoT management platforms enable communication between devices within an IoT network, allowing for accurate data collection and analysis. This data can be used to create additional insights, trigger alerts, and automate tasks.

Below, we review the five popular free IoT platforms you might consider for your business.
