  • Limited Advanced Reporting
    The reporting capabilities in the open-source version are quite basic compared to other commercial API testing tools.
  • Paid Licensing for Pro Features
    Many advanced features and more efficient workflows are locked behind the paid 'Pro' version, which might not be affordable for smaller teams or individual developers.
  • UI Glitches
    Users occasionally report glitches and bugs in the graphical user interface, which can be inconvenient and interrupt workflow.

    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.
