Simple, reliable queue-based autoscaling for your Rails app. Starting at $0/mo.
Rails Autoscale is the only autoscaler based on request queue time, not total response time. Some endpoints naturally take longer than others, and that shouldn’t trigger scaling. Rails Autoscale watches for real capacity issues to scale your app reliably and consistently.
“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!”
– Nate Berkopec, The Complete Guide to Rails Performance
Never worry about slow-downs or traffic spikes again. Stop guessing about the “right” number of dynos for your app. Let Rails Autoscale do the dirty work so you can focus on building, not managing.
Most apps are overscaled so they can handle peak traffic. Rails Autoscale easily pays for itself by scaling down your app during quieter periods, Some apps earn back half of what they were previously paying for Heroku. Try it and be amazed at how many dynos you don’t need.
“Rails Autoscale has allowed us to reduce our dyno usage for our primary application down to less than half of what we were using before, which is amazing (and allows us to not have to upgrade our Heroku plan). Thanks for making this, it really is a great little service.”
– Mark Urich
Rails Autoscale embraces the 80/20 rule and provides sensible defaults that work for 80% of apps. No sweat if you’re in the remaining 20%. Just a few tweaks is all it takes to get your app scaling smoothly.
“Rails Autoscale saved me big time yesterday!! I’m new to this and I’m learning on the fly, but you made it very easy.”
– Sam Wood
The more dynos you use, the more money you save by autoscaling. Rails Autoscale is priced accordingly. All plans get all the features. The only difference is number of dynos supported.
