I'm currently using blacksmith for my arm64 Docker builds. Unfortunately my workflow currently requires invoking a custom bash script which executes the Docker commands. Does this mean, I can now utilize Docker image caching without needing to migrate to useblacksmith/build-push-action?

Founder of WarpBuild here.
Our arm64 runners are ~2x faster than Blacksmith. This is because we use a newer generation of more powerful instances.
If you're building multi arch images, here is a page that may be useful: https://docs.warpbuild.com/docker-builders#multi-platform-bu...
We natively support multi platform builds in our drop in replacement action.

It's poor form in my opinion to come and solicit business and bash your competitors here on HN. Just a tip.

Yes! This is documented in our docs: https://docs.blacksmith.sh/blacksmith-caching/docker-builds#..., the TLDR is that you can use the `build-push-action` with `setup-only: true`.
