Where each one falls short

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

  • No managed cloud option provided by Red Hat; organisations must operate infrastructure themselves or use third-party distributions
  • Clustering and high-availability configurations require additional operational knowledge
  • Community support only; commercial support requires third-party vendors or distributions

Playwright

  • Requires programming language knowledge; not suitable for non-technical QA staff
  • WebKit implementation less mature than Chromium; occasional webkit-specific issues
  • Mobile browser testing relies on emulation, not real devices
  • No managed cloud infrastructure; users must host CI/CD runners or pay for third-party services
