    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.

    PayPal: More Frustrating Than Useful These Days

    I used PayPal for years, but lately itโ€™s been one of the most frustrating payment services Iโ€™ve dealt with. Their customer support feels almost nonexistent โ€” long wait times, scripted replies that donโ€™t solve anything, and nobody seems empowered to actually help you.

    One of the worst things is how easily they freeze or limit accounts, sometimes without clear explanation, leaving you unable to access your money for weeks. And when you try to dispute a charge or problem with an order, it often feels like you get brushed off rather than any real help.

    Overall, PayPal used to be convenient, but recent experiences on safety holds, opaque policies, and unhelpful support make it feel more like a headache than a reliable way to pay or get paid

    ๐Ÿ Competitors: Google Pay
    ๐Ÿ‘ Pros:    Widely accepted online payment method that can be convenient for basic transfers.
    ๐Ÿ‘Ž Cons:    Poor customer service, confusing policies, and frequent account holds/freezes make it unreliable
  2. PayPal is cool

    I like PayPal, it has a high security standard. Except when I am the one suffering a chargeback for some flimsy reasons.
