Published On March 26th, 2024 970Communication

“Looking for top Pubnub alternatives for your chat app development? Explore the leading competitors of PubNub that are market’s best, & offer budget-friendly, reliable, and feature-rich in-app APIs.”

These days in-app chats have become the core concept for any communication happening in the web or mobile app. As they help boost user engagement and retention rates extraordinarily. 

Whilst PubNub stands as one of the prominent providers of real-time chat APIs, the market flourishes with other plausible chat SDK providers like MirrorFly, Stream, Apphitect, and Sendbird.

Therefore, we will see how each competitor is going to help app developers integrate top-notch instant messaging services. And mates, that’s not all we’ll also focus on key features and use cases of each of the alternatives to Pubnub in the guide below. 

First, we will see,

1. What is PubNub? – A Go-To Definition

PubNub is a real-time communication API provider that allows developers to build online messaging and IoT applications on the web, Android, and iOS devices using its pub/sub model.

Their pub/sub model that is acronymed as publishers (as in senders) and subscribers (as in receivers) uses separate channels or topics to send out and receive messages. 

And though this type of architecture fosters scalability and extensibility, it also requires a substantial amount of developer’s time for building additional messaging features.  

Plus, PubNub also comes to users as an IaaS (Infrastructure as a Service) platform, where features like: 

  • Live Events
  • Real-time Messaging
  • Remote IoT Control
  • Presence Detection
  • Push Notifications
  • Geolocation
  • Data Streaming can be added.

Why should you go for PubNub alternatives?

While PubNub provides an enterprise-grade solution for creating apps, it has some drawbacks like:

1. Offers component libraries only for React, iOS, and Android.

2. Limited feature suite and chat components at high pricing.

3. Does not provide visual libraries for front-end development.

4. It is devoid of offline storage.

Well, if you ask me, are these the shortcomings of PubNub? Well, no, there are quite others and we will see the limitations of this platform by

1. Efficiency

  • PubNub does not use message sequencing, hence when a user disconnects from the network, there is no guarantee the message will be delivered.
  • It has a smaller queue size, which is 100, and hence, messages exceeding this limit will remain undelivered.
  • The platform does not persist messages when a subscriber is offline.
  • There are no built-in presence indicators in their APIs, unlike other providers like MirrorFly or Sendbird. 

2. Pricing

  • Though Pubnub has a free plan supporting up to 200 MAUs, their pricing tags seem to be complex, which could be due to the pub/sub model under which it is built.
  • Plus, they charge extra for customer support, which most of the real-time chat API providers don’t.
  • It has three plans- Standard, Gold, and Platinum, with Platinum being billed at $1500 per month. 

Doesn’t it seem like a hefty dime to spend? Well, you must check on MirrorFly’s SaaS price tiers then, they are quite a pocket-saver. For SaaP pricing, contact their sales team

3. Security

When it comes to security, PubNub is no developer’s favorite as it 

  • Lacks authentication and security mechanisms.
  • Channels can act as gateways for spam messages.
  • Absence of industry regulations and compliance standards.

and much more.

4. Scalability 

  • Businesses mostly prefer solutions that give them the benefit of scaling their apps when the user base grows. And PubNub lacks this. 
  • Secondly, it does not offer video and voice calling capabilities and enterprises must look for third-party integrations to add them.
  • Pubnub’s webhooks are known to offer basic features that limit the user interactivity within the app.

Therefore, I hope that by now, you will have an idea as to why you should choose Pubnub competitor for your chat app development process.
