How To Install Judoscale For Next.js Applications
Guided Install
When you launch Judoscale for the first time, you’ll be prompted to install a package that’s specific to your app’s language and framework. In the package installation modal, select “Node” for your language and “Next.js” for your framework.
Based on your selections, you’ll see instructions for installing the correct package and integrating it with your application. For the latest package version and detailed installation notes, see the judoscale-nextjs README.
❗ Important
This adapter is for self-hosted Next.js only (next start or equivalent). It does not work on Vercel serverless, Edge Middleware, or other per-request isolates.
If you wrap Next.js in a custom Express or Fastify server, follow the Express or Fastify install guide instead.
Once you’ve committed and deployed these changes, click the button at the bottom of the modal to verify your package setup.
Once verified, the modal will close, and Judoscale will begin collecting throughput and request queue time metrics.
Note that autoscaling is still turned off. You’ll want to review your configuration before enabling autoscaling.
