Self-hosted refers to a website or application that is hosted on a server owned and managed by the organization or individual that created it, rather than on a shared server or a server owned by a third-party hosting company.
Self-hosting gives organizations and individuals greater control over their website or application, including the ability to customize it to their specific needs and requirements.
It also allows them to manage their own data and security, and to have full control over their own web presence.
However, self-hosting also requires a greater level of technical expertise and resources, and may not be suitable for everyone.
