Qt features and specs

  • Cross-Platform Development
    Qt allows developers to write applications that can run on multiple platforms, including Windows, macOS, Linux, Android, and iOS, without the need for significant code changes.
  • Rich Documentation
    Qt provides extensive and well-maintained documentation, making it easier for developers to learn and troubleshoot the framework.
  • Mature and Stable
    Being a mature framework, Qt has a long history of stability and a strong track record in producing robust applications.
  • Comprehensive UI Components
    Qt offers a wide range of built-in UI components, which can significantly speed up the development process and provide a native look and feel on different platforms.
  • Strong Community Support
    Qt has an active and helpful community, which can be beneficial for developers seeking support or looking to collaborate on projects.
  • Performance
    Applications built with Qt tend to be efficient and performant, due to close-to-the-metal coding options and optimizations available in the framework.
  • Tooling
    Qt Creator, the official IDE for Qt, offers powerful tools for designing, coding, testing, and debugging applications, enhancing productivity.

Possible disadvantages of Qt

  • Licensing Costs
    Though Qt offers an open-source option, commercial licenses can be expensive, which can be a significant constraint for smaller businesses or independent developers.
  • Learning Curve
    The framework can have a steep learning curve for beginners, especially for those unfamiliar with C++ or the specific paradigms Qt employs.
  • Large Executable Size
    Applications built with Qt can have larger executable sizes compared to those built with more lightweight frameworks, which might be a concern for some applications.
  • Dependency on C++
    While Qt has bindings for other languages like Python (PyQt, PySide), its core is based on C++, which might not be ideal for developers looking for a more modern or different programming language.
  • Complexity in Customization
    While Qt offers many features out-of-the-box, deep customization, especially for non-standard requirements, can become complex and time-consuming.
  • Build Times
    Due to its comprehensive nature, applications using Qt can have longer build times, which can slow down the development cycle.

QuickJS features and specs

  • Lightweight
    QuickJS is designed to be lightweight with a small footprint, making it easy to embed in applications and suitable for resource-constrained environments.
  • Fast Startup Time
    QuickJS offers very fast startup times, which can be beneficial for applications that require quick script execution without a long initialization period.
  • Full ES2020 Support
    QuickJS supports the full ES2020 specification, providing modern JavaScript features and syntax, which is advantageous for developers who want to use the latest JavaScript features.
  • Embeddability
    Being easy to integrate into other applications or systems, QuickJS provides a simple C API, which facilitates embedding it in various software and platforms.
  • Single File Distribution
    QuickJS can be distributed as a single file, simplifying packaging and distribution without needing external dependencies.
  • Memory Efficiency
    Its memory efficient design allows QuickJS to run scripts in environments with limited memory resources, making it suitable for IoT devices and embedded systems.

Possible disadvantages of QuickJS

  • Limited Ecosystem
    QuickJS, being a relatively new and niche project, has a smaller ecosystem compared to more established JavaScript engines like V8, which means fewer libraries and community resources are available.
  • Performance
    While QuickJS is efficient, it may not deliver the same high-performance execution as more mature engines like V8, especially in applications requiring intensive computational processing.
  • Lack of Long-term Support
    QuickJS may not have the same level of long-term support and ongoing development as larger projects maintained by large companies or communities.
  • Single-threaded
    QuickJS runs in a single thread, which can be a limitation for applications that require multithreading support for parallel processing.
  • Limited Debugging Tools
    Compared to more popular JavaScript engines, QuickJS has fewer debugging tools and integrations, which might make development and troubleshooting more challenging.

  • Vim 9.2 Released
    You don't need V8 for running JS for scripting, you have quickjs[1] or mquickjs[2] for example. You might have problems importing npm packages, but as we can see from lua plugins you don't even need support for package managers. Performance is not as good as luajit, but it is good enough [1]: https://bellard.org/quickjs/ [2]: https://github.com/bellard/mquickjs. - Source: Hacker News / 5 months ago

  • Building a JavaScript Runtime from Scratch using C
    For those who would like a true "from scratch" implementation of JavaScript, Fabrice Bellard's QuickJS [1] is clean, readable and approachable. It's a full implementation of modern JavaScript in a straightforward project, not nearly as complex or difficult as V8. [1] https://bellard.org/quickjs/. - Source: Hacker News / 9 months ago
  • The many, many, many JavaScript runtimes of the last decade
    I see a few mentions of QuickJS, but they all refer to the fork of Bellard's QuickJS https://bellard.org/quickjs/, which I think deserves a mention. It seems to be still active (last release 2025-04-26, GitHub mirror at https://github.com/bellard/quickjs shows some activity). - Source: Hacker News / 12 months ago
  • SQLite JavaScript: Extend your database with JavaScript
    This is a fantastic approach. BTW, it looks like the js engine is "QuickJS" [0]. (I'm not familiar with it myself.) I like it because sqlite by itself lacks a host language. (e.g., Oracle's plsql, Postgreses pgplsql, Sqlserver's t-sql, etc). That is: code that runs on compute that is local to your storage. That's a nice flexible design -- you can choose whatever language you want. But quite typically you... - Source: Hacker News / about 1 year ago
