Upstra allows front-end developers to easily add powerful messaging functionalities to their native and web apps, without the hassle of deploying, maintaining any server infrastructure, or writing complicated message synchronization logic.
Upstra provides methods to allow any client to join channels and send messages. The messages will be synced up to all other clients in the same channel in real-time. The messages sent through the system can be moderated pre-delivery via automated custom spam and keyword filtering, you can also moderate all messages sent manually via our admin panel.

Start a new conversation channel with up to 300,000 concurrent participants.
