We use Ably to send out push notifications and rely on it quite heavily. We decided to go with Ably years ago to avoid having to build or manage it ourselves. It was very easy to set up and reasonable when it came to pricing, so we decided to go for "buy" rather than "build. Years later, we still use Ably for all push notifications. Initially, we thought we'd use Ably until the cost started to increase and it would be worth managing the push notification service ourselves. But the fact that we don't have to worry about them, and that the price increase due to increased traffic has been reasonable has made it that it's still not a priority Today.

Ably is a great tool for real-time communication. We have been using it for our client's EduTech Portal for the last 4 years. The support is great too. It integrates well with other technologies, easy to implement.

Our customer success reactivity. We deployed a new code that led to an explosion in the number of calls we made to Ably. Ably removed our limit to prevent blocking our feature before we needed to ask them, giving us time to adjust our code. We also like the Terraform provider to create all our apps.
