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

WSO2 API Manager

  • The free open source distribution does not include a subscription to the WSO2 Update service, so continuous improvements and security patches require a paid subscription
  • A commercial production licence is not part of the free download and comes only with a subscription
  • No subscription price is published; Basic Support and Enterprise Support both require contacting sales for a quote
  • 24x7x365 coverage requires Enterprise Support; the general query SLA is one business day
  • A Customer Success Manager is a paid optional add on covering business hours only
  • Consulting services and WSO2 Private Cloud hosting are quoted separately
