We recently published a multi-arch heroku/builder:24 builder, which is based on the heroku-24 base images and ubuntu 24.04.

The new builder is still in active development and currently includes Go, Node.js Python and Procfile buildpacks. It's available on Docker Hub like our other builders and can be used like so:

pack build my-sample-app --builder heroku/builder:24

As of today heroku/ruby is in the heroku/builder:24 and works with ARM on heroku-24 though support for JRuby is in-progress.

Jruby work is here heroku/docker-heroku-jruby-builder#33

Java merged heroku/cnb-builder-images#526

heroku/builder:24 now supports all of Heroku's officially supported languages - so ARM64 CNB support is now complete!
