What It Does

WP Post Author adds a customizable author box to your WordPress posts and pages, displaying bios, avatars, and social links. It supports multiple authors per post, guest authors without separate user accounts, and local avatar uploads so authors can avoid relying on Gravatar. The plugin also lets you assign custom author roles and display co-author contributions across archives and feeds.

Who It's For

This plugin suits multi-author blogs, news outlets, and publishing teams that regularly publish collaborative content or feature guest contributors. It is a good fit for organizations that need to credit multiple writers on a single post without creating full WordPress accounts for each one.

Who Should Skip It

Solo bloggers and single-author sites will not benefit from the multi-author and guest author features and would be better served by a lighter author box plugin. Sites already using a dedicated publishing workflow like PublishPress Authors or a full editorial suite may find this plugin redundant.

The Bottom Line

WP Post Author earns a 78.01 overall score and delivers the core multi-author and guest author features most collaborative sites need, with a strong maintenance record. The lack of any logged support activity is a minor concern, but the active development and broad WordPress compatibility are genuine strengths. It is a reasonable mid-tier choice, though Simple Author Box or PublishPress Authors may be safer picks for sites where community size and support history matter more.
