PubNub vs Radar: What are the differences?

PubNub: Build real-time apps quickly and scale them globally. PubNub makes it easy for you to add real-time capabilities to your apps, without worrying about the infrastructure. Build apps that allow your users to engage in real-time across mobile, browser, desktop and server; Radar: High level API and backend for writing web apps that use push messaging. Radar is built on top of engine.io, the next-generation backend for socket.io. It uses Redis for backend storage, though the assumption is that this is only for storing currently active data.

PubNub and Radar belong to "Realtime Backend / API" category of the tech stack.

Some of the features offered by PubNub are:

  • PubNub SDKs support over 50 of the most popular environments, including: iOS, Android, JavaScript, .NET, Java, Ruby, Python, PHP and many more.
  • Data Push - Establish and maintain persistent socket connections to any device (mobile, browser, desktop and server) and push data to global audiences in less than 录 of a second
  • Presence - Automatically detect when users enter or leave your app and whether machines are online

On the other hand, Radar provides the following key features:

  • More than just pub/sub: a resource-based API for presence, messaging and push notifications via a Javascript client library
  • Written in Javascript/Node.js, and uses engine.io (the new, low-level complement to socket.io)
  • Backend to multiple front-facing servers

Radar is an open source tool with 209 GitHub stars and 35 GitHub forks. Here's a link to Radar's open source repository on GitHub.

          I recently used PubNub to implement a realtime leaderboard into my Unity game. It was easy and straight forward to get up and running. I choose Pubnub because they had a Unity SDK and an example project which showed me how to use it. I downloaded the example project and tweaked it to fit my game.

          In their documentation I found good information about what I needed to know. Also, their support is very helpful when you have questions.

          I used PubNub because we needed a real time server for our product. Even though we selected a fixed amount paid version, the amount they charged was incredibly high, 8x of the fixed amount. We could not understand how did they do the calculation and there is no easy way of understanding it. Regarding to the analytics they have, we spent millions of messages with few hundred active users.

          Then for the second month we tried to change our architecture to decrease the messages but nothing changed. Then we wanted to get some support from them. We arranged a meeting and the person who joined the meeting didn't even have permissions to see our usage, so it was waste of time. Then they arranged another meeting WEEKS after which didn't solve anything either. As a result, we stopped using it and implemented our own simple pub-sub server.

          I was building up an Alexa Skill in which user orders a meal and its notification gets to the system of the restaurant and gets displayed which was implemented using PubNub which helped me a lot in getting real time updates and notifications. I used simple publish and subscribe module to implement it which resolved a major challenge. The 5 to 6 lines of python code get my every single chain working with notifications. Thanking PubNub for this major support for solving the challenge.

          Using websockets is something, scaling a message pipeline to thousands of concurrent connections is something else.

          I trust PubNub with what it does best, and use it as zerotoherojs.com 鈥檚 messaging pipeline.

          With PubNub, I have one less problem to think about.
