Where each one falls short

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

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

Deno Deploy

  • Smaller ecosystem compared to AWS Lambda with fewer third-party integrations
  • Less mature than established serverless platforms; newer company and platform
  • 1GB deployment size limit may restrict larger applications
  • 512MB memory limit lower than some competitors for memory-intensive workloads
  • Smaller user base and community compared to Lambda or Netlify
