Sciter features and specs

  • Lightweight
    Sciter's runtime is very small compared to other frameworks, making applications fast and efficient with low memory consumption.
  • Self-contained
    Sciter is a single DLL with no dependencies required. This simplifies deployment and reduces potential conflicts with other libraries.
  • Good performance
    The framework provides a balance between modern web technologies and high performance by utilizing native C++ code.
  • Cross-platform
    Sciter works on Windows, macOS, Linux, Android, and iOS, allowing developers to write applications that run on multiple platforms without additional effort.
  • Rich UI capabilities
    The framework allows the creation of complex and responsive user interfaces using HTML, CSS, and JavaScript.
  • Offline applications
    Sciter does not require a web server as it can run entirely offline, which is beneficial for certain application types.
  • Active development and support
    Sciter is actively maintained and supported, with regular updates and a responsive support system available.

Possible disadvantages of Sciter

  • Limited community
    Sciter has a smaller community compared to more popular frameworks like Electron or Qt, making it harder to find resources or peer support.
  • Proprietary technology
    Sciter is not open-source, which might be a drawback for developers who prefer or require open-source solutions.
  • Documentation
    While improving, some developers may find Sciter's documentation less comprehensive compared to more established frameworks.
  • Learning curve
    Developers familiar with web development will have to adapt to Sciter's specific quirks and methods, which may have a learning curve.
  • Limited integration tools
    Sciter does not have as extensive a range of third-party tools and plugins as more popular frameworks, affecting integration with other systems.

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.

    > I'm convinced that using an embedded browser engine to render app UI is the future. Sciter exists: https://sciter.com/ And it indeed is great for UI. - Source: Hacker News / 3 months ago
  • Blitz: A lightweight, modular, extensible web renderer
    I think Sciter is probably the better comparison: https://sciter.com/ It is a ground-up implementation of HTML and CSS rendering. IIRC it used to have its own programming language but now uses JS. I’ve long been interested in this kind of thing but haven’t actually played with Sciter in depth. Used to be that the licensing was a concern but looking at the site now it seems the terms have changed to be much more... - Source: Hacker News / 9 months ago
  • So You Want to Build a Browser Engine
    Seems a good place to mention https://sciter.com/ It's been on HN loads of times. A "browser" engine but very narrow scope. Works a treat for LOB type apps. - Source: Hacker News / 11 months ago

    > wondering if css and svg could be used as abstraction over graphics and UI libraries There's another project called Sciter that uses CSS to target native graphics libraries: https://sciter.com > I wonder how hard it was to implement css. I've heard it can be pretty complex. It was hard, but the biggest barrier is the obscurity of the knowledge.

  • Building Static HTML Pages with JSX Server-Side Rendering
    Built on a highly optimized JavaScript runtime powered by QuickJS, Query offers fast startup times and efficient execution. Its built-in caching mechanism further enhances performance by storing function responses, reducing database load and latency. This focus on speed makes Query a standout choice for server-side rendering, especially in applications with many components. - Source: dev.to / 4 months ago
  • Lua Is So Underrated
    Which JS VMs have you tried embedding? People in this thread have suggested https://github.com/Moddable-OpenSource/moddable, and https://duktape.org/, but I haven't tried any of them. - Source: Hacker News / 4 months ago
  • Introducing our Next-Generation JavaScript SDK
    Where the previous SDK was built on top of the QuickJS JavaScript engine and the Javy runtime, the new SDK is built on top of the Firefox browser’s SpiderMonkey engine, and the Bytecode Alliance’s StarlingMonkey runtime and ComponentizeJS WIT bindings generator. - Source: dev.to / 5 months ago
