Prototype to production in minutes not months

Prototyping with off the shelf hardware allows rapid design iteration, but bringing custom hardware to production is time intensive and costly. Other mobile or voice platforms limit available tools or controls - with Relay you can use built in functions or bring your own 3rd party services. Our Relay CLI lets you deploy production infrastructure in seconds.
