Fanout vs uWebSockets: What are the differences?
Developers describe Fanout as "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. On the other hand, uWebSockets is detailed as "Simple, secure & standards compliant web I/O for the most demanding of applications". It is a simple to use yet thoroughly optimized implementation of HTTP and WebSockets. It comes with built-in pub/sub support, HTTP routing, TLS 1.3, IPv6, permessage-deflate and is battle tested as one of the most popular implementations, reaching many end-users daily.
Fanout and uWebSockets can be categorized 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, uWebSockets provides the following key features:
- HTTP and Websockets
- Built-in pub/sub support
