Can I implement a complete chat, including UI, with no coding at all?

This depends on how much your use case overlaps with our sample application. If your service only requires basic functionality, you should be able to get an app up and running with minimal changes to our sample code. Check out UI Kits and our samples from GitHub!

However, because we also strive to create a service that flexibly adapts to diverse use cases, implementing SendBird does typically require some coding on your part to completely tailor a chatting experience for your customers.
