⚡ Open-Source Content Management Systems

Open-source content management systems are platforms whose source code is publicly available, allowing anyone to inspect, modify, and redistribute the software under open licenses.

They are typically used to build and manage websites with a high degree of flexibility, offering community-driven development, extensibility through themes and plugins, and the ability to self-host and customize functionality without vendor lock-in.
