Replacements
Listings that take over the same core job as ko.
Cloud Native Buildpacks
Tooling that turns application source code into container images without writing a Dockerfile.
Cloud Native Buildpacks builds images from source without a Dockerfile for many languages, not only Go, but gives less direct control over the resulting image.
Buildah
A command-line tool for building OCI container images without a running daemon.
Buildah builds OCI images without a daemon for any application, but images are defined by you through scripts or Dockerfiles instead of ko's Go-specific automatic builds.

Docker Buildx offers multi-platform builds through BuildKit for any language, but it requires the Docker CLI and a Dockerfile, which ko avoids.
