Observations (2)

No build tool detected

A framework (Apple) was detected but no bundler was identified. The build tool may not be detectable from output patterns, or the site may use the framework's built-in bundler.

Complex technology stack detected

8 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
