Introducing SIGNALWIRE

SignalWire is a new cloud platform for building advanced communications products, applications, or enterprise infrastructure. Our APIs, built for developers of all skill sets, enable rapid application development on a managed elastic framework.


Communications Platform


Our open source technology, FreeSWITCH, is the largest communication platform in the world, used by hundreds of millions of end users and thousands of enterprises. Service providers, enterprise IT manufactures, and the largest of IoT companies rely on us.

Reliable & Scalable

Built on new, and exclusive highly available and infinitely elastic technology, your application will scale.


Priced to disrupt price gouging incumbents that resell our technology, SignalWire presents not only a technology but budgetary advantage.


  • Elastic and Scalable

    Our technology automatically scales your communication application, so you can leave the infrastructure to us.

  • Advanced Communications Suite

    Developers are limited only by their imagination with access to full infrastructure and calls to program voice, messaging, and video.

  • Programmable Voice, SMS, MMS, Fax, Video & WebRTC

    Currently available in closed beta, we've opened up access to Voice, SMS, MMS, Fax, and Video & WebRTC APIs. We even support LaML (Legacy Antiquated Markup Languages), that may be compatible with your existing application's syntax.
