Possible disadvantages of RESTClient

    Compared to some other HTTP clients, RESTClient may lack certain advanced features like scripting or automated testing capabilities.
  • GUI Dependent
    As it's primarily a GUI-based tool, it's less suitable for users looking for a command-line interface (CLI) solution for automated testing or integration into CI/CD pipelines.
  • Platform Specific
    Being a Java-based application, it requires a Java Runtime Environment, which might not be ideal for every user or scenario.
  • Limited Community Support
    Compared to more popular tools, RESTClient might have less community support, which can lead to delays in getting help or updates.
