NW.js features and specs

  • Cross-Platform
    NW.js supports building applications that run on Windows, macOS, and Linux, enabling developers to write code once and deploy across multiple platforms.
  • Node.js Integration
    Provides deep integration with Node.js, allowing developers to leverage the vast Node.js ecosystem and modules within their applications.
  • Chromium Embedded
    Utilizes the Chromium engine to render the user interface, ensuring modern web standards compliance and high performance.
  • Full Access to Native APIs
    Offers access to all native system calls through Node.js, enabling developers to create rich desktop applications with full OS-level capabilities.
  • Single Process Model
    Allows developers to start with a simple single process model which is easy to debug and manage.

Possible disadvantages of NW.js

  • Large Application Size
    The bundling of Chromium with the application often results in larger file sizes compared to native applications.
  • Memory Consumption
    Applications may use more memory as they run instances of both Node.js and Chromium, potentially taxing system resources.
  • Performance Overhead
    There might be additional performance overhead compared to native applications due to the abstraction layers of Node.js and Chromium.
  • Limited Native UI Components
    Relies on web technologies for UI, which might not have the same look and feel as platform-native components.
  • Frequent Updates
    Keeping up with frequent updates from Chromium and Node.js can be challenging, requiring continuous maintenance to ensure compatibility and security.

Flet features and specs

  • Ease of Use
    Flet provides a straightforward API that simplifies the process of building interactive web applications, making it accessible even to those with minimal web development experience.
  • Cross-Platform Support
    Flet supports multiple platforms, allowing developers to create applications that can run seamlessly across different devices and operating systems.
  • Rapid Development
    With a focus on fast development cycles, Flet enables developers to quickly prototype and deploy applications, significantly reducing time to market.
  • Rich UI Components
    Flet offers a wide range of built-in UI components that help developers create visually appealing and functional interfaces without having to start from scratch.
  • Community and Documentation
    Flet comes with comprehensive documentation and an active community, providing valuable resources and support for developers throughout the development process.

Possible disadvantages of Flet

  • Limited Customization
    While Flet offers many built-in components, the level of customization available may not satisfy developers looking for highly tailored UI experiences.
  • Dependency on Flet Ecosystem
    Developers are tied into the Flet ecosystem, which could pose challenges if they need to integrate with other tools or want to migrate away in the future.
  • Performance Concerns
    As with many high-level frameworks, there might be performance overheads, especially for resource-intensive applications.
  • Learning Curve
    Although designed for ease of use, developers familiar with other web development frameworks may need time to learn and adapt to Flet's unique features and paradigms.
  • Emerging Technology
    Being a relatively new technology, Flet might still be undergoing changes, which may lead to stability issues or lack of long-term support.

    It's more the latter, particularly when Rust is used in libraries (eg. FastAPI) as opposed to tools, as it's destroying portability. For example I use flet[0] in some of my projects, and I have to be increasingly careful about the other dependencies as there is no support for the Rust toolchain within Dart/Flutter, and even if there was it still sounds like it'd be a nightmare to maintain.
