Welcome Back, Judoscale! We're excited to welcome Judoscale back as a Silver Sponsor of RubyConf for the second year in a row. If you've ever lost sleep wondering whether your Rails app could handle a sudden traffic spike, Judoscale is probably already on your radar and if it's not, it should be.
Judoscale is a dedicated autoscaler for Rails apps (and beyond), purpose-built around request queue time rather than blunt metrics like CPU or memory. That distinction matters: queue time tells you when your app is actually struggling, not just busy. The result is smarter, faster scaling up when you need it, down when you don't without the overprovisioning tax most teams quietly pay every month. It works across Heroku, Render, Fly.io, Railway, and Amazon ECS, with deep support for Sidekiq, Solid Queue, Good Job, and more.
The Ruby community clearly agrees Judoscale has been a fixture at Ruby conferences precisely because it's built by developers, for developers, and it shows in the quality of their gems, docs, and support.
Come say hi in Las Vegas. Judoscale will be at RubyConf 2026 July 14–16 at the Red Rock Resort. Stop by their booth to chat with the team, ask your toughest autoscaling questions, or just thank them for helping you sleep at night.
Thank you, Judoscale, for your Silver Sponsorship and for being part of the community again this year. We're glad you're back.
