Possible disadvantages of FastAPI

  • Learning Curve for Asynchronous Programming

  • 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.

    I dont understand the hype

    I have used HubSpot, and Iโ€™ll be honest it wasnโ€™t love at first use. People hype it as the all-in-one marketing/crm/sales tool, but for me it often felt more complicated than it needed to be.

    First off, the interface looks clean, but navigating deep menus and figuring out where things live took longer than I expected. Especially as a smaller user not an enterprise team it sometimes felt like I was learning a giant software just to do basic things like setting up an email or tracking a lead.

    The CRM itself works fine in theory, but customizing fields and pipelines was way clunkier than other CRMs Iโ€™ve tried. I felt like I was bending the tool to my process instead of the other way around and thatโ€™s backwards in my book.

    Another thing: some features feel half-baked or overly complex, especially if youโ€™re not a marketing automation pro. Workflows, sequences, analytics theyโ€™re powerful, but they also require a lot of clicking and re-reading help docs before you get them right.

    And then thereโ€™s pricing. HubSpotโ€™s free plan looks great on paper, but you hit limits fast and once you upgrade, it gets pricey quick for what you actually use. I ended up feeling like I was paying for a lot of features I barely touched.

    That said, HubSpot does have strengths it integrates a ton of tools under one roof and works well if youโ€™re already deeply invested in their ecosystem. But for me personally? It never clicked the way simpler, more intuitive platforms did.

    Bottom line: HubSpot is solid and powerful, but I didnโ€™t love it felt too big, too complex, and not really tailored to the way I work.

    Great CRM for Small and Growing Sales Teams

    We started with Hubspot and it has served us well for over 3 years now. Its a straight forward CRM that serves the needs of our sales team well without overcomplicating things with hard to configure settings or other functionality we don't need. The user interface is much easier to navigate compared to other CRMs I worked with in previous roles.
