Features and specs

What each product offers, as listed by its team.

ReactOS 4 features
HasData 9 features
  • 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

  • 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.
  • Sub-2s Median Latency
    Every API request completes in about 2.1 seconds on average, even under high load.
  • 99.9% uptime SLA
    Stay online with highly reliable servers, automated failover, and 24/7 infrastructure monitoring.
  • Up to 10M Requests/Hour
    Handle massive scraping operations with infrastructure built to support 10 million hourly API calls.
  • 100M+ Proxies
    Access hundreds of millions rotating IPs for global coverage and unblockable data collection.
  • JavaScript Rendering
    Extract content from dynamic, JavaScript-heavy websites without manual browser emulation.
  • Auto-Retry & Failover
    Built-in error handling and retries ensure high success rates even under volatile network conditions.
  • Clean Structured Output
    Deliver consistent, parsed JSON with metadata, images, text, listings, and links.
  • Full Anti-Bot Protection
    Bypasses Cloudflare, Datadome, and Akamai automatically — no proxy rotation or browser setup required.
  • Easy Integration
    Connect in minutes using clear API documentation, SDKs, and straightforward REST architecture.
