    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 of FastAPI

  • 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.

  1. Kurslog team
    ยท Working at Kurslog ยท

    When our backend team needs to build services for data parsing, aggregators, or high-load APIs, FastAPI is our absolute go-to choice. It completely lives up to its name-development speed is outstanding.

    The combination of Pydantic for data validation and built-in async support keeps our shared codebase clean, strictly typed, and reliable. But the biggest highlight for our cross-functional team is the automatic generation of interactive OpenAPI (Swagger) documentation. Our frontend and mobile developers no longer have to wait for backend engineers to manually update API docs; everything stays perfectly in sync automatically. It has drastically improved our team's communication and delivery speed.

  • Ask HN: What Are You Working On? (September 2025)
    I'm working on Vedro, a Python testing framework as a pytest alternative without the magic and with clear output. The main idea is that tests should just be Python: plain `assert` statements instead of custom matchers, no fixture magic, and when tests fail you get readable diffs that actually show what went wrong. Tests can be simple functions or structured with steps that self-document in the output.... - Source: Hacker News / 10 months ago

  • vedro-fn: Compact Tests, Clear Results
    One of the greatest strengths of Vedro is its scenario-based approach to testing. By modeling tests as clear-cut user stories, Vedro helps you write behavior-driven tests that reflect real-world usage. However, while scenario classes are fantastic for complex tests (like end-to-end scenarios), they can sometimes feel verbose when writing smaller, more straightforward checks, such as unit tests. - Source: dev.to / over 1 year ago
  • Vedro Hooks
    Vedro offers powerful extensibility through its plugin system, allowing you to create robust, reusable solutions that can be shared across different projects and teams. But what if you're just experimenting with your codebase, prototyping a concept, or adding a small tweak? Writing a full plugin might feel like overkill. Thatโ€™s where vedro-hooks comes in. - Source: dev.to / over 1 year ago
