heroku/builder builder images feature Heroku's native Cloud Native Buildpacks. These buildpacks are optimized and make use of many CNB features.
heroku/builder-classic builder images feature Heroku's classic platform buildpacks, shimmed for compatibility with the Cloud Native Buildpacks specification. These buildpacks don't take advantage of many CNB features and are less optimized, but offer a wider variety of languages and legacy language feature support.
heroku/buildpacks builder images feature a mix of both native and shimmed Heroku Cloud Native Buildpacks. These images will not be supported in future stack versions (22 and beyond).
Usage
pack build myapp --builder heroku/buildpacks:20
