Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

SST

  • Primarily optimized for AWS with Cloudflare support
  • Learning curve for developers unfamiliar with infrastructure concepts
  • Limited documentation for some advanced use cases

Buildah

  • Linux only, with no native macOS or Windows support
  • Scriptable builds are powerful but less portable and less familiar than a Dockerfile
  • Narrow by design: it builds images and does not run them, so it needs Podman or another runtime alongside

No. Buildah reads Dockerfiles if you have them, but images can be built entirely from shell commands instead.
