Frequently Asked Questions: Chat SDKs & APIs

What is a chat SDK?

A SDK is a software development kit that comprises a set of tools (including documentation, code samples, code libraries, debugger, and guides) that is organized as one installable package. A chat SDK provides all the functionality needed to build a feature rich chat app.

What is a chat API?

An API (application programming interface) serves as intermediary software, facilitating communication between two platforms or applications. It can exist as a standalone solution, but is often included within an SDK. Chat API makes live chat and instant messaging possible in any mobile app or website by connecting your client-side application to an entire backend communication platform.

Does QuickBlox chat work on web and mobile?

Yes. We offer a range of cross-platform software including a chat SDK for mobile (Android & iOS) and a chat API for websites, plus chat SDKs for Flutter and React Native so that you can build applications accessible by smartphone, tablet, and desktop.
