Visual design flow

Unlock the potential of your applications with Flow Designer, a robust web-based development environment where data-driven applications can be prototyped, built, and deployed with ease.

Flow Designer is:


Prototype your Internet of Things (IoT) and M2M applications using node-based flows and test applications within scalable on-demand compute environments.

  • Pre-configured nodes allow easy access to multiple data sources, cloud services, device profiles, and communication methods
  • Integrations are done for you


Flow Designer nodes are open source and available via GitHub where you can suggest features and contribute your own improvements, giving you the access and flexibility you need.

  • Flows are saved so they can be reused later, reducing development time


  • Built to our exacting requirements that encompass specifications for technology, controls, and processes
  • World-class network services
