I need a news feed/messenger plugin/standalone App which can be embedded into my WordPress website.
Existing plugins/Software is acceptable. It does not have to be installed on the WordPress website as long as it can be embedded with HTML.
This needs to update live on the website without refreshing the whole page.
This needs to have the latest posts at the top
It needs to be easy to add posts to this.
Need to be able to easily add an image into the post.
It needs to be responsive to screen size.
Admin login will be required to post
See examples below of similar.
