Kylix: The Rise and Fall of Borland’s Cross-Platform IDE
Kylix, introduced by Borland Software Corporation in 2000, stands as one of the most ambitious and short-lived attempts at creating a cross-platform Integrated Development Environment (IDE) for software development. This IDE was primarily designed to bring the power of Delphi’s Object Pascal language to Linux, aiming to compete with other platforms like Microsoft’s Visual Studio and Eclipse. However, Kylix’s initial promise eventually gave way to a series of challenges that led to its eventual demise. In this article, we explore the rise, features, limitations, and ultimate downfall of Kylix, examining how it reshaped Borland’s trajectory in the software development market and the broader tech landscape.

The Genesis of Kylix
At the dawn of the 21st century, Borland Software Corporation, which had already established a significant presence in the software development world with products like Delphi and C++ Builder, decided to tap into a new market: Linux development. The move came at a time when Linux was gaining traction as a robust, open-source alternative to proprietary operating systems like Windows and macOS. However, despite its growing adoption, Linux lacked a comprehensive, user-friendly development environment for building GUI applications. Borland sought to fill this gap by bringing its Delphi IDE, which was highly praised for its ease of use and powerful visual design tools, to the Linux platform.
Kylix was essentially a Linux version of Delphi, with a few key modifications to make it compatible with the open-source operating system. It featured a rich graphical development environment and support for both Object Pascal (the language of Delphi) and C++. The primary goal of Kylix was to make Linux development accessible to developers who were already familiar with Delphi, thus fostering a smoother transition from Windows to Linux for enterprise applications.
Key Features and Capabilities
Kylix offered a number of innovative features that aimed to differentiate it from other available development tools at the time. Some of the key highlights include:
-
Cross-Platform Development: Kylix was designed to enable developers to create applications that could run on both Windows and Linux platforms with minimal changes to the underlying code. This was achieved by leveraging the cross-platform capabilities of the Delphi environment, which was known for its rapid application development (RAD) framework.
-
Graphical User Interface (GUI) Design: One of the standout features of Kylix was its drag-and-drop GUI designer, a hallmark of Borland’s Delphi products. This visual development tool allowed developers to build complex interfaces without writing a single line of code, which made Kylix highly appealing to those working on enterprise applications that required rich UIs.
-
Support for Object Pascal and C++: Just like Delphi, Kylix supported Object Pascal, a high-level language known for its simplicity and speed, as well as C++, which was more widely used in enterprise-level applications. This made Kylix a versatile tool for a range of different development needs.
-
Database Integration: Kylix was designed with strong database integration in mind. It offered support for popular database engines like InterBase (which was also a Borland product), MySQL, and PostgreSQL. This made it an attractive option for developers working on data-driven applications.
-
Component Library: Kylix came with a comprehensive library of pre-built components, including those for database access, network communication, and user interface design. These components allowed developers to quickly assemble applications without having to write everything from scratch.
-
Native Code Compilation: Kylix allowed developers to compile their applications into native code for the target platform, meaning that applications could run with minimal overhead and take full advantage of the underlying operating system’s performance.
Kylix’s Limitations and Challenges
Despite the promising features, Kylix was not without its limitations and challenges, many of which ultimately contributed to its decline:
-
Limited Linux Adoption: In the early 2000s, while Linux was becoming more popular as a server operating system, it was still far from being a mainstream choice for desktop computing. Many developers were hesitant to adopt Kylix for Linux development because of the platform’s relatively small user base. In addition, the lack of standardization in Linux distributions at the time made it difficult to create applications that worked seamlessly across different versions of the operating system.
-
Incomplete Feature Set: Kylix, although feature-rich, lacked some of the capabilities that developers expected from an enterprise-level IDE. For example, it did not have as extensive debugging tools or as refined a performance analysis suite as its Windows-based counterparts, making it less appealing for complex application development.
-
Compatibility Issues: Kylix was designed to be cross-platform, but in practice, developers found that the code they wrote for Linux often required significant tweaks to run on Windows, and vice versa. This incompatibility undermined Kylix’s value as a true cross-platform tool and made the development process more cumbersome than anticipated.
-
Competition: By the time Kylix was released, other cross-platform development environments were emerging, such as Eclipse and the Mono project, which focused on bringing .NET applications to Linux. These alternatives presented a significant challenge to Kylix, as they were open-source and enjoyed wide community support.
-
Market Shifts: As Linux matured as an operating system, its primary focus remained on server environments, and the demand for Linux desktop applications remained limited. This shift in the market meant that Kylix’s target audience—the developers of Linux desktop applications—was smaller than Borland had hoped.
The Decline of Kylix
Kylix’s future began to falter soon after its initial release. Despite the excitement surrounding its cross-platform potential, several factors led to its decline. Firstly, Borland’s commitment to the product began to wane as the company faced financial difficulties and shifted its focus towards other areas of software development. As a result, Kylix did not receive the updates and improvements necessary to stay competitive with other IDEs, both on Linux and Windows.
Secondly, the Linux community itself was divided over the use of proprietary tools like Kylix. Many developers in the open-source community were wary of Borland’s closed-source approach, preferring to rely on tools like GCC (GNU Compiler Collection) and open-source alternatives like Eclipse. This made it difficult for Kylix to gain traction within the very community it was designed to serve.
By 2003, Borland announced that it would no longer continue to develop Kylix. The IDE was discontinued, and Borland eventually abandoned the Linux market altogether, focusing more on its Delphi and C++ Builder products for Windows.
Aftermath and Legacy
Despite its relatively short lifespan, Kylix had a lasting impact on the software development world, particularly in the context of Linux development. It highlighted the challenges and limitations of bringing proprietary development tools to an open-source platform, and it underscored the importance of community involvement in the success of any software project.
While Kylix itself is no longer in use, its influence can still be seen in the development of modern IDEs, particularly in the realm of cross-platform development. The challenges that Kylix faced also contributed to the growth of open-source tools like Eclipse and Qt, which are now popular choices for Linux developers.
Kylix also served as an early indication of the complexities involved in cross-platform development, especially in a world where multiple operating systems have distinct behaviors and requirements. Its failures and lessons continue to inform the development of modern IDEs and cross-platform frameworks, even as new tools like Visual Studio Code and JetBrains’ IntelliJ IDEA take center stage in the development world.
Conclusion
Kylix remains an interesting chapter in the history of software development, particularly for those who witnessed the early days of Linux adoption. Despite its shortcomings and ultimate failure to gain widespread traction, Kylix’s attempt at creating a cross-platform development environment for Linux marked a pivotal moment in the evolution of programming tools. The lessons learned from its rise and fall continue to influence how developers approach cross-platform development today. Though Borland’s ambitions for Kylix were not fully realized, the IDE’s impact on the broader development community and its role in the maturation of both Delphi and Linux development are undeniable.
While Kylix itself is now a relic of the past, it stands as a testament to the innovative spirit of software development—a reminder of how the pursuit of a great idea can sometimes be stifled by technical, market, and community challenges.
