    Although the documentation is extensive, there might be limited real-world examples and case studies readily available compared to more mature frameworks.

    Deploying FastAPI applications might be more complex in comparison to traditional synchronous frameworks, mainly due to the need for asynchronous server setups.

  • Limited Free Plan
    The free plan comes with limitations, which may restrict access to some advanced features and functionalities.
  • Complex for Large Campaigns
    While the platform is easy to use for small to medium campaigns, managing very large and complex campaigns can become cumbersome.
