  • Generated Code Quality
    While the tool generates a significant amount of code, the quality of the generated code might not always match hand-crafted solutions, potentially requiring manual refinements and adjustments.
  • Heavy Dependency
    Relying on a code generator creates a dependency on the tool, which may complicate upgrades over time, especially if custom templates or configurations are heavily used.
  • Learning Curve
    There is a learning curve associated with understanding the OpenAPI specification and how to effectively use the generator, particularly for complex APIs and integrations.
  • Maintenance Overhead
