Open Source Software vs Proprietary Software

Open Source Software (OSS)

  • Open Code: The source code is publicly available for anyone to see, modify, and redistribute.
  • Collaborative Development: Anyone can contribute to the software’s development by fixing bugs, adding features, and improving functionality.
  • Cost-Effective: Often free or significantly cheaper than proprietary software, reducing costs for individuals and organizations.
  • Transparency: Openness of code builds trust and allows users to verify what the software does.
  • Security: Large community involvement can lead to faster bug fixes and improved security.

Examples: Linux operating system, Firefox web browser, LibreOffice productivity suite, WordPress content management system.

Proprietary Software

  • Closed Code: The source code is kept secret, only accessible to the software’s developer or owner.
  • Controlled Development: Development is limited to the software company’s employees or contracted developers.
  • Costly: Usually licenses require purchase or subscription fees, potentially leading to higher overall costs.
  • Black Box: Users trust the software to work as advertised without knowing how it does so.
  • Security: May be slower to fix bugs as updates rely solely on the developer.

Examples: Microsoft Windows operating system, Adobe Photoshop editing software, Microsoft Office productivity suite, QuickBooks accounting software.
