Why we built Ably

When we launched Ably in 2013 the available platforms didn’t meet more than the basic requirement of delivering real time data updates. They didn’t provide the functionality that developers really ought to be able to rely on.

We built Ably from the ground-up to create a service that would comfortably encompass not just the demands of the most popular consumer apps, but that would lead the way in enabling the massive growth in instantaneous and high value data exchanges between global businesses.
