Vivaldi features and specs

  • Customization
    Vivaldi offers extensive customization options, allowing users to tweak the browser's appearance and functionality extensively. Users can adjust themes, modify the interface, and use custom shortcuts.
  • User Interface
    The user interface is highly flexible and can be tailored to individual preferences. For instance, users can reposition tabs, split screens, and even stack tabs for better organization.
  • Privacy and Security
    Vivaldi focuses on privacy, providing built-in features such as an ad blocker and tracker blocker. The browser does not track or profile its users.
  • Performance
    Vivaldi is generally snappy and capable of handling a large number of open tabs without significant slowdowns. It is built on Chromium, which provides a stable and quick browsing experience.
  • Built-in Tools
    Vivaldi includes a range of built-in tools like a notes manager, screen captures, and customizable web panels that improve productivity without needing extra extensions.

Possible disadvantages of Vivaldi

  • Complexity
    The plethora of customization options can be overwhelming for new users. The interface may appear cluttered compared to simpler browsers if not configured properly.
  • Resource Usage
    Vivaldi can be more resource-intensive compared to other browsers due to its additional features and customization capabilities. This may lead to higher memory usage.
  • Extension Compatibility
    While Vivaldi supports Chrome extensions, some may not perform as expected due to the browser's unique features and customizations.
  • Learning Curve
    Users coming from more straightforward browsers might need some time to adapt to Vivaldi's extensive features and customization options.
  • Frequent Updates
    While frequent updates can be seen as a positive, they could also be viewed as a nuisance to users who prefer a more stable and less frequently changing browser experience.

ReactOS features and specs

  • Open Source
    ReactOS is an open-source operating system, which means its source code is freely available for anyone to view, modify, and distribute. This allows developers and contributors to participate in its development and enhancement.
  • Windows Compatibility
    ReactOS aims to be binary-compatible with Windows, especially Windows Server 2003, meaning it can run many Windows applications and drivers without modification. This could be beneficial for users who rely on legacy Windows software.
  • Lightweight
    ReactOS is designed to be lightweight, requiring fewer system resources compared to modern Windows operating systems. This makes it suitable for older hardware that may not support contemporary operating systems efficiently.
  • Freedom from Licensing Costs
    Being free and open source, ReactOS eliminates the cost associated with purchasing Windows licenses, providing an alternative for users who wish to avoid these costs.

Possible disadvantages of ReactOS

  • Incomplete Development
    ReactOS is still in the alpha stage of development, which means it is not yet stable or feature-complete. This can lead to various issues such as system crashes, incomplete features, and compatibility problems.
  • Limited Application Support
    Despite its goal of Windows compatibility, ReactOS does not support all Windows applications and drivers, particularly newer ones that require features not yet implemented in ReactOS.
  • Lack of Commercial Support
    Unlike Windows, which has extensive commercial support from Microsoft and third-party service providers, ReactOS lacks official commercial support, which may be a concern for enterprise environments.
  • Security Concerns
    As ReactOS is still under development, it may not have implemented all necessary security features and updates that a more mature operating system might have, potentially leading to security vulnerabilities.

  • Vivaldi is considered a good choice for users who prioritize flexibility and control over their browsing experience. Its extensive personalization options set it apart from other browsers, although it might have a steeper learning curve for those who are not as tech-savvy.

Why this product is good

  • Vivaldi is a web browser that is known for its customization options, privacy features, and user-centric design. It offers a range of unique features such as tab stacking, a built-in ad blocker, and customizable keyboard shortcuts.

Analysis of ReactOS

Overall verdict

  • ReactOS is a promising project with potential, but it is still in the alpha stage of development. This means it may not be stable enough for everyday use and might lack support for some hardware and software. While it offers an interesting alternative to Windows, users seeking stability and complete compatibility may find it falls short.

Why this product is good

  • ReactOS is an open-source operating system intended to be binary-compatible with applications and device drivers made for Microsoft Windows. The project aims to provide users with a free alternative to Windows, which can run Windows applications natively without the need for emulation or virtualization.

Recommended for

  • Technology enthusiasts who enjoy testing and contributing to open-source projects.
  • Developers interested in operating system design and contributing to an open-source effort.
  • Users looking to experiment with a Windows-compatible OS alternative for non-critical tasks.

The 7 best web browsers in 2025
And there's plenty more to like about Vivaldi. Its unique tab management tool allows you to stack multiple tab rows on top of each other, so you can group certain websites to clear clutter and make more room on your main tab row. On the sidebar, you can similarly pin panels for quick access to anything, like your notes, reading list, messaging websites, and browsing history.

Brave Alternative - 8 Privacy-Focused and Reliable Options
Compared to Brave, Vivaldi lacks privacy features, but the huge extension support compensates for that. In my experience, both Brave and Vivaldi offer the same browsing speed, and the system impact was also equal.

The Best RSS Feed Readers for Streamlining the Internet
Vivaldi's RSS reader is new, and features are somewhat limited. For example, it doesn't handle some of the extras that other services do, like newsletters and Facebook pages. If you just want a simple reader to subscribe to a few feeds and you don't need a mobile client or all the bells and whistles, this is a great choice. Vivaldi's RSS reader is free and built-in to the...

  • Firefox will have an option to disable all AI features
    The solution for the (as of yet) small group of people who cares about these things is very simple: community driven forks. With the bonus that you also get a set of great (and per fork different yet handy) features. These include: Waterfox (Firefox) - https://www.waterfox.com/ Zen Browser (Firefox) - https://zen-browser.app/ Librewolf (Firefox) - https://librewolf.net/ Helium (Chrome/Chromium) -... - Source: Hacker News / 8 months ago
  • I tried 6 next-gen browsers - here's what I found
    Last, but not least in my journey to find the perfect browser for me is Vivaldi. This browser was developed back in 2015 by a former Opera co-founder and markets itself to primarily power users. The browser strives to be the all-in-one solution, fully customizable per every userโ€™s needs. - Source: dev.to / 10 months ago
  • Washington Post's Privacy Tip: Stop Using Chrome, Delete Meta Apps (and Yandex)
    I use Vivaldi[1], it seems to work fairly well. Also has built-int adblocker although I'm not sure how good it is compared to Ublock or others. [1] https://vivaldi.com/. - Source: Hacker News / about 1 year ago

  • Microsoft Needs Windows Lite
    There is already a "Windows Lite", and it's called ReactOS [0]. Except, the last thing we need is for Microsoft to own / embrace-extend-exterminate this. It's best that it's kept as an independent project, enabling developers to target the Windows API if they feel like it, while ensuring that they only target the Wine-compatible parts of it, which then enables their software to also run seamlessly on other... - Source: Hacker News / about 2 months ago
  • Microsoft's "Fix" for Windows 11: Flowers After the Beating
    Kinda off-topic, but I wonder if a hypothetical OS that reimplements the Windows APIs (like ReactOS[0], but with perfect modern hardware support) would be better for end users than a Linux distro with a modern DE. In the past, this hypothetical OS would be a revolution. But I feel that, in recent years, this gap is not as big anymore and Linux supports way more apps than in the past. Such an OS might even not be... - Source: Hacker News / 5 months ago

  • Using GNU toolchain for Windows kernel-mode drivers
    Compiling into object code is easy but linkig is tricky. For reference of possilbe options, I used an example from ReactOS project. ReactOS is the only working (sort of) full reverse-engineered NT operating system kernel. It is a cool project. ReactOS Github repo has a collection of build options for kernel-mode drivers that can be carved out of CMake files. - Source: dev.to / 10 months ago
  • YouTube is taking down videos on performing nonstandard Windows 11 installs
    Would this help you? https://reactos.org/ This is an open source reimplementation of winxp. I think they can even run drivers made for windows now. - Source: Hacker News / 10 months ago
