If you need a free author bio box for WordPress, start with the job you need it to do: Simple Author Box is the clearest fit for a basic byline card, while WP Post Author and Molongui Authorship describe broader options for guest authors and multiple contributors. PublishPress Authors and Starbox are also listed in WordPress.org’s author-bio category, but the available information is not detailed enough to compare their current free features responsibly. That means there are five credible options to investigate—not a verified ranking of seven free plugins.
Plugin features, free-versus-paid boundaries, and WordPress compatibility can change. The details below reflect official listings and documentation accessed on September 30, 2026; check each live listing before installing.
Which author bio box plugin should you choose?
| Plugin | Best starting point | What the available evidence establishes |
|---|---|---|
| Simple Author Box | A basic author or guest-author box | WordPress.org describes responsive boxes and social icons. The listing reported 90,000+ active installations and testing through WordPress 7.1.2 when accessed in 2026. |
| WP Post Author | A site considering guest authors or multiple contributors | Its listing describes multiple authors, guest authors without accounts, local avatars, ratings, registration forms, and block, widget, and shortcode output. Confirm which features are available free. |
| Molongui Authorship | More control over author display and guest/co-author handling | The developer describes configurable profile information, layouts, and social links. Some advanced features are explicitly Pro-only. |
| PublishPress Authors | A candidate to investigate for author management | It appears in WordPress.org’s author-bio category, which reported 20,000+ active installations in 2026. Current free-tier scope was not established here. |
| Starbox | A candidate to investigate for author boxes | It appears in WordPress.org’s author-bio category, which reported 10,000+ active installations in 2026. Current free-tier scope was not established here. |
Installation counts are WordPress.org directory snapshots, not ratings or evidence of quality. Likewise, a “tested up to” label is a developer-reported compatibility signal, not a guarantee that a plugin will work with every theme, editor, or plugin combination.
What to check before installing
Choose based on the publishing workflow and where the box needs to appear, rather than the number of features in a plugin description.
Recommended Free Tools
#1 Best Overall
- Single-author posts: Check whether the box appears automatically and whether you can control the displayed name, biography, avatar, social links, and styling.
- Guest contributors: Verify that guest profiles can be created without WordPress user accounts and find out how those profiles are assigned to posts.
- Co-authored posts: Check whether the plugin supports multiple authors and whether it shows one shared box or a separate box for each author.
- Placement: Confirm whether you can use automatic placement, a block, widget, shortcode, or manual insertion—and whether your preferred method is included in the free version.
- Content types: If you need boxes on pages or custom post types, confirm support for those exact types. Availability may differ between free and paid tiers.
- Compatibility: Review the listing’s tested WordPress version, recent update information, and user reports relevant to your theme and editor.
- Free-tier limits: Compare the features you actually need with the plugin’s current free-versus-Pro documentation. A feature mentioned in a general product listing is not automatically free.
What each plugin’s official information says
Simple Author Box
Simple Author Box is the most straightforward starting point for a responsive author or guest-author card with social icons. WordPress.org’s listing reported version 2.61, a minimum of WordPress 4.6, testing through WordPress 7.1.2, and 90,000+ active installations when accessed in 2026. These are directory details, not independent tests; revisit the WordPress.org listing for current metadata.
WP Post Author
The WP Post Author listing describes a wider set of tools, including multiple authors, guest authors without accounts, locally uploaded avatars, ratings, registration forms, and display through a Gutenberg block, widget, or shortcode. That list does not establish that every feature is included free. Identify the specific capability you need and verify its current tier before building a workflow around it.
Molongui Authorship
Molongui’s WordPress.org listing and changelog record an update dated September 11, 2026, that added WordPress 7.1 compatibility. The developer’s feature comparison describes configurable author information, multiple layouts, and social links, while identifying custom post type support, shortcode availability, and structured data as Pro features. Its FAQ also says custom post types require Pro. Check the current free/Pro comparison against your intended placement and content types.
PublishPress Authors
PublishPress Authors appears in WordPress.org’s author-bio category, which reported 20,000+ active installations when accessed in 2026. That count can help you identify it as an option to investigate, but it does not show which current features are free or establish a particular workflow fit. Review its live listing and documentation before choosing it.
Starbox
Starbox also appears in the WordPress.org author-bio category, which reported 10,000+ active installations when accessed in 2026. The directory figure is not a measure of plugin quality, and the available feature information does not establish its current free-tier boundaries. Check its current listing and documentation to see whether it supports your required profile fields, placement, and content types.
Why this is a five-plugin shortlist, not a seven-plugin ranking
WordPress.org’s author-bio category includes these five prominent options, but the available official information does not verify seven plugins’ current free functionality in enough detail for a fair comparison. Adding two more names would create the appearance of a complete “best seven” list without enough evidence to tell readers what they can actually use for free.
For the same reason, this is a shortlist rather than a scored ranking. Active-installation totals do not establish quality, and the information available does not provide comparable independent testing of performance, display quality, or reliability. Check the live plugin pages for changes to counts, compatibility claims, and feature tiers.

The official sources cited here describe plugin features, not measured effects on rankings, trust, or conversions. Treat an author box as a way to display contributor information—not as a demonstrated SEO improvement. If author details matter to your readers, make sure the information is accurate and useful regardless of which plugin displays it.
