Difference between search.maven.org and mvnrepository.com

Question

What's the difference between https://search.maven.org/ and https://mvnrepository.com/ ?

Answer 1

The first one is the official central search engine of Central Repository handled and very well maintained by

• Sonatype Inc.
• with support etc. https://central.sonatype.org/
• Status Information about Central: https://status.maven.org/

Whereas the part https://repo.maven.apache.org/maven2/ is the real Central repository (distributed world wide via CDN) which is being used by default by Apache Maven , Gradle etc.

The second one is a search engine (not always up to date) and sometimes misused as a repository, which does not work cause it's only a search engine . Not really visible by whom it's being maintained/used etc.
