Open Source projects often rely on community contributions and may lack formal technical support. Closed Source products often come with customer support, user guides, and warranty, offered by the company that owns the software. This makes Closed Source software often more user-friendly but at the expense of adaptability.

Open Source software allows developers and users to access, modify, and distribute its source code. This fosters a collaborative environment and often results in rapid development and debugging. Closed Source software, on the other hand, keeps its source code hidden and proprietary, which often results in more polished but less adaptable products.

Open Source platforms usually allow for a great degree of customization, as users can modify the source code to better fit their needs. Closed Source software typically offers less flexibility because you cannot access or alter the source code, thus limiting customization to the features that the developers provide.
