We are mostly using PubNub for payload sending and for live chat. We are a mobile-based application with an admin side, so it's a live chat application. Whenever a user comes online or offline or sends a live chat request to someone or a message, we use PubNub for that.

I used PubNub in my last company from 2018 to February 2022 for IoT products. We used it to broadcast the status of IoT devices to every client on Android or iOS phones. For PubNub, we sent the status of CAMI, a product in which we collected data from the vehicle, including speed, humidity, temperature, and other statistics, to all clients using PubNub. This is how all client applications on Android or iOS phones received the status of the vehicle on which each car was registered. In most cases, PubNub worked very well. We conducted load testing with multiple vehicles and multiple user accounts, and it performed quite well with 15 users and more than 50 vehicles at a single time. I also used PubNub for one of the challenges or competitions in my company where I created an Android application that sends the location and other data about the smartphone in case it gets lost through a server to a remote web application, and we used PubNub to track the smartphone.
My main use case for PubNub is to provide a feature in a certain project where two people can communicate or chat. After searching quite a few options like Socket.IO and other SDKs, I found out that PubNub is the current most used SDK, and it is quite useful in terms of its benefits, which is why I picked PubNub for my use case. In my applications, I used PubNub to implement a scenario where users can sign up with multiple accounts, allowing each user to send friend requests to each other. Once the friend request gets accepted, they build a connection via a pub-sub model created between them. Then I have a feature called chat, where they can communicate seamlessly through the available friends from that window. I have used PubNub in a React Native application to implement real-time chat and messaging features, and my overall experience with the platform has been positive, especially for building scalable communication features with minimal back-end effort. One of the things I appreciated most about PubNub was the ease of integrating real-time messaging into the app, with clear SDK documentation. Setting up channels, message listeners, and presence tracking was straightforward, and I use it for one-to-one chat, message delivery updates, and online/offline user status. The performance was reliable, and message delivery was fast even with multiple active users. PubNub helped reduce development time as many real-time features were already handled by the platform. I appreciated features having message history and push notification support, which made the overall chat experience smoother for users, and the React Native integration worked well across both platforms, Android and iOS.
