We primarily use Heroku for Progressive Web Apps (PWAs) and to build bots.

It is also used for mobile web applications such as Telegram and WhatsApp.

The websites are used for a variety of use cases, and one of the ones that we develop is for e-commerce. It can fill in forms and we have robot advisors to assist people with decision making.

Our clients use it to deploy the production, development, and staging environments. Its version depends on our clients' needs. Usually, it is a customized system that needs to be scaled.

My primary use case of this product is for hosting Ruby applications. Probably more than half of the people at our company use Heroku for applications. I am a customer of Heroku and a Ruby programmer. 

We deploy a lot of our production servers on Heroku. We use it for deploying production apps to AWS.

Within our organization, there are roughly seven people using this solution — mostly software engineers and QA engineers. 

We are using Heroku to create applications for the education sector.
