The Inspire Chat app, a web and mobile group chat application designed to motivate and inspire users through shared messages, quotes, and media, has transitioned to using PubNub's serverless infrastructure for enhanced real-time chat capabilities. Initially, the development team at Interestix Corp managed their own chat server using ejabberd, which required significant effort due to its use of the Erlang programming language and the need to create custom libraries for various platforms. The switch to PubNub allowed them to leverage its reliable infrastructure and easy-to-integrate SDKs across multiple platforms, reducing development time and enabling them to focus on improving user-facing features. PubNub's consistent API calls across platforms and features such as Online Presence Detection and Storage and Playback further streamlined the development process by eliminating the need for custom backend solutions, ultimately enhancing the user experience. With future plans to utilize additional PubNub features like mobile push notifications and security encryption, the team aims to continue improving the app's functionality and user engagement.
