Horizon vs PubNub: What are the differences?
Developers describe Horizon as "A realtime, open-source JavaScript back end from RethinkDB *". Horizon provides a complete backend that makes it dramatically simpler to build, deploy, manage, and scale engaging JavaScript web and mobile apps. Horizon is extensible, integrates with the Node.js stack, and allows building modern, arbitrarily complex applications. On the other hand, *PubNub** is detailed as "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.
Horizon and PubNub can be categorized as "Realtime Backend / API" tools.
Horizon is an open source tool with 6.77K GitHub stars and 389 GitHub forks. Here's a link to Horizon's open source repository on GitHub.
I am building an IoT application that will utilize connected air quality sensors to provide real-time indoor air quality in offices. I want to be able to share this data with a few different databases, etc.
Wondering if anyone has any advice on which real-time streaming API would be best for this sort of application, or even how I should think about it?
For IoT, we support MQTT along with websockets and SSE. The pattern you're suggesting that involves harvesting data from devices and soaking into a database is easy to achieve with one of the Ably integrations (Serverless functions/webhook) . Here are some tutorials to do things like this: https://ably.com/tutorials/reactor-event-zapier#step2-mqtt-ably
We use Pusher at www.justlearn.com. It works fine. When you reach more users, Pusher gets expensive. We use Pusher for live chat between users. Their software is easy to use. We have had issues with auth on Pusher.
