Overview of Proprietary Software

Software is a set of instructions that tells a computer's hardware to perform a specific task. The set of instructions that is the basis of any software is known as source code. Some of the examples of software are : Games you play on your electronic devices, OS and applications (Google, Amazon, FB, IG, Twitter, etc.).  

When the developers release their software to the end-users (customers), the software is either released as open source or closed source.  

• Open source software refers to the software in which source code is visible to the public and the software is usually free to use.
• Anyone can use the source code, study how it works, distribute and/or modify the source code to improve the performance of the software.
• Closed source software is the opposite of open source as you can guess.
• Closed source software is also popularly known as proprietary software and commercial software.

In this article we will know about what is proprietary software, which is better open source or proprietary software and finally advantages and disadvantages of proprietary software. So, let's start exploring the topic.

What is Proprietary Software?

Proprietary means ownership. If anyone wants to use the proprietary software, then a license has to be purchased from the owner for using the software. The source code of this kind of software is not visible to anyone except the owner. The owner can be the developer or the organization releasing the software. So even when you pay the fee to obtain the license, you don't have any access and rights to view, copy, distribute or modify the source code of the proprietary software. 

In other words, you simply pay to get a "license to use as per the guidelines given by the owner" nothing else. As a buyer, you can use it. And the owner can officially distribute the software to any number of buyers. If the ownership is transferred to someone else, then that one gains the authority to view, copy, distribute, modify the proprietary software.  

History of Proprietary Software

Proprietary software refers to software owned by individuals or companies who restrict its use, modification, and distribution through licenses. In the early days of computing, software was often shared freely, but as the industry grew in the 1970s and 1980s, companies began to protect their intellectual property with proprietary licenses. The 1990s saw the dominance of major companies like Microsoft and Adobe, while the 2000s introduced open-source software as a viable alternative. Today, proprietary software coexists with open-source solutions, adapting to trends like cloud computing and SaaS.

Types of Proprietary Licenses

• Perpetual License: Users pay a one-time fee for lifetime access to the software.
• Subscription License: Users pay recurring fees for periodic access to the software, including updates and support.
• Site License: A single fee grants unlimited software access for all users at a specific site or within an organization.
• Floating License: A license for a set number of concurrent users, allowing shared use across multiple users.
• Trial License: Temporary, often free access for a limited period, used for evaluation purposes.

Open source or Proprietary software, Which One is Better ?

Open source software may seem to be the best choice since it's usually free and the source code is accessible without any restrictions.  

But that software is not customized or may not be in perfect form for the users. So the community around the world collaborates to keep improving the source code by removing errors, adding features to make the software more efficient and convenient.

Some features and technical support of the open source software may incur charges. And user-friendliness of the open software may not be as good as proprietary software.  

Proprietary software needs to be purchased in order to use it and has some restrictions as mentioned in the guidelines. Yet this software is highly customized for specific purposes and more user friendly than the open source.  

Advantages of Proprietary software

• Stability. It will work perfectly as you expected while purchasing the software.
• Reliable software and, customer service is easier to access.
• Highly user-friendly and the software is customized to specific purposes.
• Unique. Packed with multiple features.

Disadvantages of Proprietary software

• Even when you purchase the license, you have several restrictions on using the software and you can't modify it.
• The usage of the software may be restricted like 'can only be installed on one computer'. So depending on the agreement, the installation of software on different workstations varies.
• If it has any missing features or bugs, then you have to wait until they are resolved by the owner.

Some Examples of Proprietary Software :

• Microsoft Windows
• macOS
• iOS
• Avast antivirus
• Adobe Photoshop, illustrator and the rest of the software in the suite

Proprietary Software vs. Other Types of Software

Proprietary Software is developed and sold by a company or individual with restrictions on its use and distribution. Open-Source Software allows free access to the source code for modification and redistribution. Freeware is available for free but not open for modification, while Shareware offers limited functionality for free and requires payment for full access. Proprietary software generally involves licensing fees and has controlled usage rights, whereas open-source and freeware often provide broader access and modification rights.

Proprietary Software License

A proprietary software license is a legal agreement defining how users can interact with software. It dictates how the software can be used, whether it can be modified or redistributed, and what kind of support is provided. Typically, it restricts users from accessing the source code and limits the software’s use to the terms specified by the vendor, such as requiring payment for use or forbidding redistribution.

Restrictions Defined in a Proprietary Software License

Proprietary software licenses include restrictions such as:

• No Reverse Engineering: Users cannot decompile or modify the software’s code.
• No Redistribution: Users cannot share the software with others.
• Limited Use: Specifies how and where the software can be used.
• No Unauthorized Copying: Prohibits making extra copies beyond what is allowed.
• Non-Transferable License: The license cannot be transferred to another person.

Conclusion

Proprietary software has a well-established history marked by its transition from a niche technology to a dominant force in the software industry. It differs from open-source and freeware by having strict licensing terms and controlling access to source code. Proprietary licenses come in various forms, each with specific terms for usage and distribution. Understanding these licenses and their restrictions is crucial for both users and developers in navigating the software landscape effectively. The future of proprietary software will continue to evolve with technological advancements and market demands.
