Where each one falls short

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

Puppeteer

  • Chrome and Firefox only, with no Safari or WebKit story
  • Not a test framework: assertions, retries and reporting need Jest or similar bolted on
  • Bundles a Chromium download, which makes installs large and awkward in constrained CI images

Swagger/OpenAPI

  • The OpenAPI Specification itself is licensed under Apache License 2.0 and free to use; SwaggerHub is a separate paid tool built on top of it
