Best Instant Messaging API for Secure and Scalable iOS Chat Apps?

Developing Nodes
1

I am an iOS developer working on a project to build a secure and scalable instant messaging application**. The app is intended for use cases such as customer support chat, internal team collaboration, healthcare communication, and marketplace messaging**.

During my research, I came across several messaging API providers, including MirrorFly, Sendbird, Apphitect, and Rocket.Chat. Each platform claims to offer enterprise-grade messaging features, strong security, and scalability.

Before choosing a provider, I would like clarity on the following:

  1. What defines modern instant messaging software today?
  2. How do Chat APIs and SDKs accelerate app development?
  3. Which provider performs best for iOS apps in real-world production environments?
  4. What technical and business factors should influence the final decision?

I would appreciate expert recommendations and practical guidance.

Hi, your post got flagged as spam as it doesn't really mention anything to do with Node-RED. Perhaps you could expand on this a little. Are you wanting to create something that integrates with Node-RED?
