Co-Authors Plus v4.1.1 is a free WordPress plugin with 20K+ active installs, 3.5/5 rating from 77 reviews, updated June 26, 2026, requires WordPress 6.4+ & PHP 7.4+. Download the latest GPL version below — free, with live demo included.
Assign multiple bylines to posts, pages, and custom post types via a search-as-you-type input box. Co-authored posts appear on a co-author’s archive page and in their feed. Co-authors may edit the posts they are associated with, and co-authors who are contributors may only edit posts if they have not been published (as is core behavior).
Add writers as bylines without creating WordPress user accounts. Simply create a guest author profile for the writer and assign the byline as you normally would.
On the frontend, use the Co-Authors Plus template tags or the block editor blocks to list co-authors anywhere you’d normally list the author.
