Features and specs

What each product offers, as listed by its team.

FastAPI 7 features
Things 7 features
  • 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.
  • Type Checking and Validation
    With Pydantic models and Python type hints, FastAPI provides automatic data validation and type checking, reducing the chance of runtime errors.
  • Ease of Use
    Its syntax and design make it easy to learn for Python developers, offering a smooth development experience while reducing boilerplate code.
  • Asynchronous Support
    FastAPI supports asynchronous programming, allowing for better performance for I/O-bound operations, making it optimal for handling many simultaneous connections.
  • Extensive Documentation
    It has comprehensive and well-structured documentation, which is very useful for both beginners and advanced users.
  • Community and Ecosystem
    FastAPI has a growing community and ecosystem, with many plugins and integrations available to extend its functionality.

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.
  • User Experience
    Things is known for its clean, intuitive, and beautifully designed user interface, making it easy to use.
  • Integration with Apple Ecosystem
    Seamlessly integrates with macOS and iOS devices, offering features like Handoff and deep Apple Calendar integration.
  • Powerful Task Management
    Supports projects, areas, headings, and tags, providing a robust system for managing complex tasks and workflows.
  • Quick Entry
    Provides a quick entry function allowing users to capture tasks efficiently, which can later be categorized and detailed.
  • Updates and Support
    Regularly updated with new features and enhancements, backed by reliable customer support.
  • Keyboard Shortcuts
    Offers extensive keyboard shortcuts for power users to navigate and manage tasks quickly.
  • Natural Language Processing
    Allows users to input tasks using natural language, which is then intelligently parsed and scheduled.

Possible disadvantages

  • Cost
    Things requires a one-time purchase for each platform (macOS, iOS), making it relatively expensive compared to some subscription-based competitors.
  • Platform Limitation
    Only available on Apple devices (macOS and iOS), making it inaccessible for users on Windows, Android, or other platforms.
  • No Collaboration Features
    Lacks built-in collaboration tools, which can be a drawback for teams looking to share and manage tasks collectively.
  • Learning Curve for Advanced Features
    While the basic interface is user-friendly, fully utilizing advanced features can require time and a deeper understanding.
  • Limited Automation
    Offers fewer automation options and integrations compared to some competitors like Todoist or Microsoft To Do.
