    The free version of Elfsight comes with limitations on the number and types of widgets available, which might not be sufficient for all users.
  • Loading Speed
    In some instances, adding multiple widgets from Elfsight can impact the website's loading speed, affecting overall performance.
  • Dependency on Third-Party
    Using an external service like Elfsight means relying on a third-party for updates and maintenance, which could be a concern for some users.
  • Customization Limitations
    Despite high customization options, certain advanced functionalities might still require additional coding or may not be supported at all.
  • Data Privacy
    As with any third-party service, there can be concerns around data privacy and security, particularly in how user data is handled and stored.
  • High Performance
    Built on Starlette and Pydantic, FastAPI is one of the fastest frameworks for Python, providing high performance due to its asynchronous request handling.
  • Automatic Interactive API Documentation
    FastAPI automatically generates interactive API documentation via Swagger UI and ReDoc, which are very helpful for development and testing.

Possible disadvantages

  • Learning Curve for Asynchronous Programming
    Although FastAPI itself is easy to learn, grasping the concepts of asynchronous programming in Python can be challenging for beginners.
  • Complex Dependencies
    Using Pydantic for advanced validation can make the request models complex, requiring a deeper understanding of Pydantic and its functionalities.
  • Early Stage Libraries
    Some third-party libraries and extensions specifically tailored for FastAPI might still be in early stages of development and lack long-term stability.
  • Limited Real-World Examples
    Although the documentation is extensive, there might be limited real-world examples and case studies readily available compared to more mature frameworks.
  • Deployment Complexity
    Deploying FastAPI applications might be more complex in comparison to traditional synchronous frameworks, mainly due to the need for asynchronous server setups.
