Railway Autoscaling Done Right

“Chameleon has been extremely stable thanks to Judoscale. We have very high spikes in traffic, and I don’t even have to think about it. ”
Queue time, not CPU or memory
Autoscaling based on CPU and memory is inconsistent and unreliable. Queue time is the true measure of server capacity, and Judoscale is the only autoscaler for Railway that does it.

Queue time isn’t just for web services. Judoscale also uses queue latency to autoscale your background workers, ensuring your job queues never back up.
Autoscaling at ludicrous speed
A capacity issue needs to trigger autoscaling as quickly as possible, and Judoscale is the fastest autoscaler available. Our autoscaling algorithm runs every 10 seconds, ensuring your app scales up before users notice an issue.
Customize your autoscale behavior
Every app is different, and so Judoscale gives you complete control over how your app autoscales. You can scale by multiple instances at a time and tweak the frequency of scaling. Each service is configured independently with a few simple sliders.

What languages and frameworks does Judoscale support?
We support many web frameworks and job/task queues for Ruby, Python, and NodeJS. See the full list in our docs.
What data can Judoscale access in my app?
Our adapter libraries only collect queue-related metrics for requests and job queues along with basic process metadata. No actual request or job data is ever collected.
Can we have a call to see if Judoscale makes sense for my app?

You guys are rock stars!! I think this is the 3rd time now that you've already had a solution ready to go to solve our problem. This is exactly what I was looking for!!
Judoscale’s deep integration with Sidekiq queues let us easily tag which queues we wanted a faster response. We were able to tune our scaling sensitivity for exactly our usage pattern of intermittent batches of large jobs.
As we onboarded larger customers, we expected traffic peaks that needed to be addressed quickly. Judoscale did exactly that.
If I was the king of the world, I would make it illegal to horizontally scale based on execution time. Scale based on queue depths, people!
Chameleon has been extremely stable thanks to Judoscale. We have very high spikes in traffic, and I don’t even have to think about it.
We could see the care in Judoscale’s documentation, the gems were well-documented and designed with a general sense of quality.
Request queue time is the single most important part of this. Scaling by CPU and memory consumption makes no sense—your server should have stable memory usage and nearly 100% CPU utilization.
We’re really impressed by the simplicity and ease of use of Judoscale. We’ve gone from constant worries over site performance, to complete confidence in our configuration. What a great tool!
