JS Morisset

The JSM Show Post Metadata plugin displays post (ie. posts, pages, and custom post types) meta keys (aka custom field names) and unserialized values in a metabox at the bottom of the post editing page.
Note that if you’re using WooCommerce HPOS (High-Performance Order Storage), available since WooCommerce v8.2, then your WooCommerce orders are NOT post objects and you should use the <a href="https://wordpress.org/plugins/jsm-show-order-meta/" rel="ugc">JSM Show Order Metadata</a> plugin instead.
There are no plugin settings – simply install and activate the plugin.
<h4>Available Filters for Developers</h4>

<pre><code>'jsmspm_metabox_table_metadata' ( array $metadata, $post_obj )

JSM Show Post Metadata

I've started recently to use this plugin to discover post meta values, I must say it's cleaner than other plugins I've used before.

Thanks for the latest update release 2.0.0, the ability to have post meta updated without having to load the page is pretty awesome.

I use the plugin almost everyday. I recommend it to anyone who wants to see what's in post meta.

Keep it up!

Useful and Very Clean Post Meta Viewer Plugin

It's great for letting me see hidden metadata without having to open up the database.  Plus, it's great for allowing non-technical users to see the information without the risk of sending them to the database.  

Super helpful tool!


I'm definitely not making full use of its potential but, for what I need it, it has proved to be dependable and very useful.



Thank you for sharing your work.

This plugin is incredibly helpful when converting and managing legacy websites, especially for uncovering all kinds of hidden metadata - even the obscure ones.


Thanks a lot for this great plugin!

Show post metadata (aka custom fields) in a metabox when editing posts / pages - a great tool for debugging issues with post metadata.

Aura Frontend Inspector is a professional-grade debugging tool designed for WordPress developers and agencies who need to ensure their sites are compliant, accessible, and error-free.
Unlike traditional auditors, Aura is built for the AI era. It features the ARF 1.0 (Aura Report Format), a structured data standard that allows you to copy detected issues directly into AI tools like ChatGPT or Claude to receive instant, context-aware code fixes.

Every issue detected by Aura includes a “Copy AI Prompt” button. This assembles a high-signal prompt containing the exact HTML snippet, site environment, and error metadata in the ARF 1.0 format. Simply paste it into your favorite LLM for a precise solution tailored to your WordPress site.
<h3>Professional Accessibility (A11y) Auditing</h3>
Ensure your site meets WCAG 2.1 standards with real-time detection of: 
* Duplicate IDs: Finds elements sharing IDs that break screen readers and ARIA landmarks. 
* Missing Labels: Identifies form inputs without accessible names. 
* ARIA Integrity: Detects broken <code>aria-labelledby</code>, <code>aria-describedby</code>, and hidden focusable elements. 
* Semantic Structure: Validates heading levels (H1-H6), main landmarks, and page titles. 
* Interactive Elements: Flags non-interactive elements with click handlers and buttons without types.
<h3>Developer-First Features</h3>
<ul>
<li>Persistent Logging: Issues are stored in a dedicated database table with rate-limiting and deduplication.</li>
