Software can be classified into two broad categories based on how their source code is distributed and controlled. Proprietary software restricts access to its source code, keeping control with the company or individual who created it. Open source software, on the other hand, makes its source code freely available for anyone to view, modify, and distribute under specific licensing conditions.

What is proprietary software?
Proprietary software is developed, owned, and controlled exclusively by a specific company or individual. The source code remains protected and inaccessible to users. Only the organization that created the software has the right to modify it. Users must purchase or license the software to use it, and this license comes with strict restrictions.
These restrictions typically include limits on the number of installations allowed, prohibitions on sharing the software with others, and restrictions on modifying the code. Users need a valid license to install proprietary software on their computers. The company providing the software is also responsible for maintenance, updates, and technical support, which are usually offered as paid services.
Examples of widely used proprietary software include Microsoft Office, Adobe Creative Cloud, Windows, macOS, and Norton AntiVirus. These applications are developed and maintained by for-profit organizations that protect their intellectual property rights through copyright and licensing agreements.
What is open source software?
Open source software makes its source code publicly available on the internet. Programmers can freely access, study, modify, and enhance the software without any cost. The Open Source Initiative defines open source licenses as those that allow software to be freely used, modified, and shared.
This software is developed and tested through open collaboration by a community of developers. Unlike proprietary software, there is no single company controlling its development. The open source community manages the software collectively, with contributions from developers worldwide. While the software itself is generally free, some organizations offer commercial support services for maintenance.
Open source software grants users several fundamental freedoms. They can use the software for any purpose, study how it works, modify and improve the program according to their needs, and redistribute copies without restrictions. Popular examples include Linux, Android, Firefox, WordPress, Python, VLC Media Player, and GIMP.
Key differences between proprietary and open source software
Source code accessibility
The most fundamental difference lies in source code access. Proprietary software is not distributed with its source code, which remains owned and controlled by a private team. Open source software makes the source code publicly available, allowing anyone with programming knowledge to examine and understand how the software functions.
Cost and licensing
Open source software can typically be obtained free of charge, though users may incur costs for hosting, implementation, and ongoing developer maintenance. Proprietary software requires upfront payment and often involves recurring licensing fees. Users may also face long-term contracts that lock them into using specific software even if they find alternatives.
Flexibility and customization
Open source software offers unlimited customization options. Developers can modify the code to suit specific requirements, extend functionality, and integrate it with other systems. Proprietary software is rigid due to restricted source code access, hard-coded features, and locked-in product scope. Customization is limited to the options provided by the vendor.
Development and maintenance
Proprietary software is developed by a closed team within the company that owns it. The vendor is completely responsible for fixing bugs, releasing updates, and adding new features. Open source software benefits from community-driven development, where multiple contributors worldwide collaborate to improve the software. Bug fixes in open source software are often faster due to community involvement.
Support and documentation
Proprietary software typically comes with dedicated customer support provided by the vendor. Users can contact technical support teams for assistance, though this service is often included in the licensing fee. Open source software relies primarily on community support through forums, documentation, and mailing lists. However, many open source projects also offer commercial support options for organizations that need guaranteed assistance.
Understanding open source licenses
Open source software is distributed under various licenses that define how the software can be used, modified, and redistributed. In India, popular licenses include GPL, Apache License, and MIT License, each with its own specific rules.
Copyleft licenses
Copyleft licenses require that any modified or derivative versions of the software must also be distributed under the same license terms. The GNU General Public License is the most well-known copyleft license. It ensures that software remains free by requiring all modifications to be released under the same terms. Other copyleft licenses include the Affero GPL, which adds network usage provisions, and the Lesser GPL, which allows proprietary programs to link to open source libraries.
Permissive licenses
Permissive licenses impose minimal restrictions on how software can be used and redistributed. The MIT License allows users to do almost anything with the software, including creating closed source versions, as long as copyright notices are preserved. The Apache License provides similar freedoms but explicitly addresses patent rights. The BSD licenses come in different variants with varying levels of requirements regarding attribution and name usage.
Legal considerations in India
Software in India is protected under the Copyright Act of 1957, which recognizes computer programs as literary works. The Indian Copyright Act protects software as a distinct category of creative work. Developers using open source software must ensure compliance with license terms, maintain proper attribution for third-party code, and conduct regular software audits to identify potential license violations.
Choosing between proprietary and open source software
The choice between proprietary and open source software depends on specific project requirements, budget constraints, technical expertise, and long-term goals. Organizations with limited budgets and strong technical teams often prefer open source solutions for their flexibility and cost savings. Companies requiring extensive support, refined out-of-the-box features, and minimal customization may opt for proprietary software.
Many successful technology strategies involve using a combination of both types. Businesses might use proprietary software for critical applications requiring guaranteed support while leveraging open source tools for development, infrastructure, and internal systems. This hybrid approach allows organizations to balance cost, control, and functionality.
What do you think? How does the choice between proprietary and open source software impact innovation in the technology sector? What factors should Indian startups consider when deciding which type of software to build their products on?
