RenderWhen for Blocks adds conditional visibility to every block in the WordPress block editor. Decide who sees what, and when, with a panel that reads exactly how you’d say it out loud:
<blockquote>
Show this block when the user is logged in. 
 Show this block when the date is between March 1 and March 31. 
 Show this block when the device is mobile.
</blockquote>
RenderWhen is built around two ideas that set it apart from other visibility plugins:
<ul>
<li>Server-side rendering only. When a block is hidden by a condition, it is not rendered into the page output at all. No CSS <code>display: none</code>, no DOM bloat, no leaked content in view-source. Search engines, screen readers, and your page weight all benefit.</li>
<li>Public Conditions API. The three built-in conditions are registered through the same public API your plugin or theme can use to add your own. No hacks, no internal-only code paths.</li>
</ul>
In the editor, a subtle dashed border marks every block that carries a visibility rule, so a rule-bearing block never disappears from the published page as a surprise. A “Preview as audience” sidebar lets you simulate a logged-out visitor, a specific role, or a different device class right in the editor — blocks whose rule would hide them fade out with a clear badge, no save-and-reload cycle required.
<h4>Built-in conditions (v1.0)</h4>
<ul>
<li>User state — show to logged-in users, logged-out users, or specific roles</li>
<li>Date range — show between two datetimes, timezone-aware</li>
<li>Device type — show on desktop, tablet, or mobile</li>
</ul>
<h4>Designed for</h4>
<ul>
<li>Agencies and freelancers building client sites who want a clean, predictable visibility tool</li>
<li>Developers who need an extension point, not another walled garden</li>
<li>Anyone who cares about page weight and SEO hygiene</li>
</ul>
<h4>What this plugin deliberately does NOT do</h4>
It does one thing well rather than ten things adequately. Out of scope in v1.0:
<ul>
<li>Multi-condition AND/OR groups (planned for v1.1)</li>
<li>URL / cookie / referrer / geolocation conditions</li>
<li>WooCommerce, ACF, or membership integrations</li>
<li>A settings dashboard</li>
</ul>
If you need those today, <a href="https://wordpress.org/plugins/conditional-blocks/" rel="ugc">Conditional Blocks</a> and <a href="https://wordpress.org/plugins/block-visibility/" rel="ugc">Block Visibility</a> are excellent and well-established choices.
<h4>For developers</h4>
Register a custom condition in three steps. Implement the interface, add it to the registry, ship.
<pre><code>add_action( 'renderwhen_register_conditions', function ( $registry ) {
 $registry->register( new My_Plugin\\Conditions\\Country_Condition() );
} );
</code></pre>
Your condition class implements <code>RenderWhen\Conditions\Interface_Condition</code>:
<pre><code>namespace My_Plugin\Conditions;

use RenderWhen\Conditions\Interface_Condition;

class Country_Condition implements Interface_Condition {
 public function get_id(): string {
 return 'country';
 }

 public function get_label(): string {
 return __( 'Visitor country', 'my-plugin' );
 }

 public function get_schema(): array {
 return array(
 'type' => 'object',
 'properties' => array(
 'countries' => array(
 'type' => 'array',
 'items' => array( 'type' => 'string' ),
 ),
 ),
 );
 }

 public function evaluate( array $settings, array $context ): bool {
 $current = my_plugin_detect_country();
 return in_array( $current, $settings['countries'] ?? array(), true );
 }
}
</code></pre>
The full set of public filters:
<ul>
<li><code>renderwhen_register_conditions</code> — register your conditions here</li>
<li><code>renderwhen_evaluate_{condition_id}</code> — last-mile override of any condition’s result</li>
<li><code>renderwhen_render_block_hidden</code> — fires when a block is hidden, useful for cache busters and SEO tools</li>
<li><code>renderwhen_device_type</code> — swap in your own device detection</li>
</ul>
The plugin is developed openly on GitHub. Issues, PRs, and architecture discussions welcome: https://github.com/abhishekfdd/renderwhen

RenderWhen for Blocks

Show or hide any block when conditions match. Developer-first API and true server-side rendering — hidden blocks never reach the browser.
