Schema markup validator launched, replacing Google’s structured data testing tool
the Structured data testing tool by Google is a popular web application used by SEOs and webmasters to debug and validate Schema.org structured data.

The news was not well received as the rich results test is very limited in scope and usefulness.
Several months later, on December 15, 2020, Google announced that it would keep the tool but move it to a new domain due to the comments received.
To better support open standards and the development experience, we are refocusing the structured data testing tool and migrating it to a new domain serving the schema.org community by April 2021.

Schema.org. and keep it relevant to schema.org users.

Well spotted, although I was going to announce it after some documentation tweaks! Think of yourself as early adopters.
New Schema markup validator if it is virtually identical to Google’s structured data testing tool.
Although the tool is marked as beta, SEOs and webmasters can start using it right now.
