Open source refers to software whose source code is freely available for anyone to view, modify, and distribute. Open source platforms like WordPress allow developers to customise and improve the software. This collaborative approach often leads to robust, frequently updated systems. Open source platforms can be cost-effective and flexible, as they’re not tied to a single vendor. However, they might need more technical knowledge to implement and maintain.
