Autoscale The Right Way
using request queue time and job queue latency

“We have a wide variance in both server load and response times, which makes trying to scale based on response time completely ineffective. Judoscale just works. We love it! ”
Queue time is the metric that matters
For web requests and job queues, queue time tells us when more or fewer servers are needed. Secondary metrics like response time or CPU don’t measure capacity like queue time. The difference is predictable, reliable autoscaling.

You need to autoscale more than just your web processes. If you have asynchronous job or task queues, reliable throughput is a must. Judoscale prevents backed-up queues by scaling your async processes automatically.
Scale up before your users notice
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.
Cut your hosting cost by 50% or more
Most apps are way overprovisioned to avoid slowdowns or downtime at peak traffic. Judoscale makes that unnecessary. We make sure you only pay for the resources you need—no more, no less.
Precise control when you need it
You can scale up by multiple dynos at a time to handle traffic spikes, and you decide how frequently you scale up and down. Each process is configured independently with a few simple sliders.

Sometimes you have different scaling needs based on the time of day or day of the week. Judoscale lets you prepare for these times by setting custom scaling schedules.

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 hosting platforms does Judoscale support?
Heroku, Render, and Amazon ECS for now, but we’re working on more. Let us know what platform you want us to support.
What happened to Rails Autoscale?
We rebranded as Judoscale in 2022 to be more inclusive to other frameworks. Same product, same team, just a new name.
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?
