Fanout vs Pusher: What are the differences?
What is Fanout? Realtime APIs made simple. Fanout makes it easy to build realtime APIs and apps. The product is a cross between a reverse proxy and a message broker. Receivers subscribe to channels, and published data is delivered in realtime.
What is Pusher? Hosted APIs to build realtime apps with less code. Pusher is the category leader in delightful APIs for app developers building communication and collaboration features.
Fanout and Pusher can be primarily classified as "Realtime Backend / API" tools.
Some of the features offered by Fanout are:
- Reverse proxy -- integrate realtime with any level of your technology stack, not just your front end.
- Interoperable -- Add realtime to any API, no matter your backend or database, without changing any of your existing API contracts.
- Open -- cloud or self hosted, it’s up to you. We don’t believe in vendor lock-in.
On the other hand, Pusher provides the following key features:
- Easily build scalable in-app notifications, chat, realtime graphs, geotracking and more in your web & mobile apps with our hosted pub/sub messaging API.
- Send programmable push notifications to iOS and Android devices with delivery and open rate tracking built in.
- Easily add 1-1 and group Chat to your web & mobile apps. Presence, message storage, rich media, notifications, typing indicators and more.

In the original prototype all the communication was handled by a backend server. Each client connected directly to the server using the socket.io library. This quickly proved to be messy and unreliable, especially on the cheap server being used to host it.
Websockets proved to be a little more reliable, but still just as messy and not all browsers support them. That's when the project was switched over to use Pusher. Using Pusher has allowed all but the initial connection code to be off-loaded onto the client. Now instead of communicating through a self-hosted server, clients can communicate pretty much peer-to-peer over Pusher.
Pusher is used to send update notification whenever Lapzbot joins a server.
