  • Privacy Concerns
    Some users have raised concerns about PayPal's data privacy practices and how their information is shared with third parties.

  • Deployment Challenges
    Deploying Haystack-based applications may require additional work and expertise in cloud services and containerization, which can be a barrier for some developers.
  • Continuous Maintenance
    As an open-source project, keeping up-to-date with the latest changes and updates can require continuous maintenance and monitoring.
  • Limited Real-World Examples
    While the documentation is extensive, there are relatively fewer real-world example projects available compared to some other NLP frameworks, which can make it harder to understand how to apply it to specific use cases.
  • Learning Curve
