• Potential Compatibility Issues
  Some users might encounter compatibility issues with certain website platforms or plugins, which can require additional troubleshooting or support.

  Some users may find the level of customizability offered by PageSpeed Ninja to be limited, especially if they have specific or advanced optimization needs that the tool does not address.

  Being an open-source project allows anyone to inspect, modify, and contribute to the codebase, fostering community involvement.

Possible disadvantages

• Limited Features
  Fast-cli primarily focuses on download speed and lacks more detailed metrics like latency and upload speed, which may be important for some users.
• Dependence on Fast.com
  The tool relies on the fast.com service, which could limit its functionality if the service faces downtime or changes that affect compatibility.
• Lack of Detailed Reporting
  Unlike some other speed test tools, fast-cli doesn't provide extensive options for historical data tracking or detailed reporting.
• No Graphical User Interface
  As a command-line tool, it lacks a graphical user interface, which might not be suitable for users who prefer visual interfaces over text-based ones.
