Question

I have a need for syncing and have choice overload. It seems like the options available include: Faye, Juggernaut, Cool.io, plain old eventmachine

Any suggestions? What are the most popular, especially in the RoR community?

Thanks for any explanation around your suggestion.

I just implemented Juggernaut in one of my apps and I think it’s awesome. It uses Redis for its pub/sub features and Socket.IO to maximise browser/mobile support.

Here’s a discussion comparing it with Faye. I don’t believe Faye uses Socket.IO which is one of the reasons I chose Juggernaut. I also liked the simplicity of Juggernaut as it matched my particular use case.

Juggernaut uses Node.js for its server making it easily scalable and provides a Ruby gem that makes publishing messages onto Redis a piece of cake.

Here’s a quick post on setting it up on Ubuntu 10.04.

You could also look at Pusher which is a service that does it all for you.
