A staging site, also known as a development site or testing environment, is a replica of a live website that is used to test changes or updates before they are made live on the actual site.
Web designers and developers use staging sites to test new features, plugins, themes, and other updates in a safe and controlled environment, without affecting the live site. This allows them to identify and fix any bugs or issues before deploying changes to the live site, which can prevent potential downtime or other negative impacts on the user experience.
Staging sites are typically created on a separate server or subdomain from the live site and may require a separate login or password to access. They can be built using the same technology stack and configuration as the live site, but with different data, such as a copy of the site’s database. Once changes have been tested and approved on the staging site, they can be deployed to the live site with confidence.
