Ralley vs Kestrel: What are the differences?

Developers describe Ralley as "Queue as a service". Simple, robust queue as service - that requires absolutely no setup as it works over HTTPS Simply prefix ANY https request with ralley.to/ and we’ll queue, and then forward the request with the exact same method/body/headers/parameters.

It lets you queue, retry, delay or schedule cron jobs - with a best-in-class job console to see exactly the status of every job.. On the other hand, Kestrel is detailed as "Simple, distributed message queue system". Kestrel is based on Blaine Cook's "starling" simple, distributed message queue, with added features and bulletproofing, as well as the scalability offered by actors and the JVM.

Ralley and Kestrel belong to "Message Queue" category of the tech stack.

Some of the features offered by Ralley are:

• Queue
• Cron
• Delay

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

• Written by Robey Pointer
• Starling clone written in Scala (a port of Starling from Ruby to Scala)
• Queues are stored in memory, but logged on disk

Kestrel is an open source tool with 2.79K GitHub stars and 324 GitHub forks. Here's a link to Kestrel's open source repository on GitHub.
