wpsignal

<p>WordSocket sends realtime events from your WordPress site to connected browsers.<br />
When content changes: a post is published, a comment is approved, an option is updated: the plugin pushes the event to subscribers instantly via WebSocket (with SSE fallback).</p>
<p>On WordPress 7.0+, WordSocket also registers as a WebSocket-based Yjs sync provider for realtime collaborative editing in the block editor, replacing the default HTTP polling transport with a low-latency WebSocket connection.</p>
<p>WPSignal is an independent service and is not affiliated with or endorsed by the WordPress project.</p>
<p><strong>Features:</strong></p>
<ul>
<li>One-click automatic connection via the WPSignal dashboard (no API key required)</li>
<li>Manual connection via API key for advanced setups</li>
<li>Disconnect button with inline confirmation, removes the site from the server immediately</li>
<li>WebSocket-first with automatic SSE fallback</li>
<li>Per-site JWT signing secrets: each site’s connection tokens are cryptographically isolated</li>
<li>AES-256-GCM encrypted event payloads: the WPSignal relay receives ciphertext only and never has access to plaintext message content</li>
<li>Admin toggle to disable the collaboration provider and fall back to WordPress HTTP polling</li>
<li>Built-in triggers for post updates and custom post types</li>
<li>Custom trigger builder: map any WordPress action hook to a realtime event</li>
<li>Public JavaScript API (<code>window.WPS</code>) for themes and plugins to share the connection</li>
<li>Extensible connection token: <code>wpsignal_token_channels</code> and <code>wpsignal_token_channel_prefixes</code> filters let other plugins add channels and namespace permissions to the JWT without modifying core</li>
<li>Admin explorer page with live event log, publish form, and token inspector</li>
<li>Short-lived JWTs (5 min) with automatic refresh</li>
</ul>
<p><strong>How it works:</strong></p>
<ol>
<li>Install the plugin and connect to the WPSignal service.</li>
<li>When content changes in WordPress, the plugin encrypts and publishes an HMAC-signed event to the WPSignal server.</li>
<li>The server pushes the ciphertext to all browsers subscribed to that channel.</li>
<li>The browser decrypts the payload and dispatches <code>wpsignal:*</code> DOM events. The relay never sees plaintext content.</li>
<li>On WordPress 7.0+, the block editor uses the same WebSocket connection for collaborative editing with no extra configuration.</li>
</ol>
<h4>Third-Party Service</h4>
<p>This plugin connects to the <strong>WPSignal service</strong> at api.wpsignal.io for the following operations:</p>
<ul>
<li><strong>Site registration</strong>: when you connect in the admin (via the automatic one-click flow or by entering an API key manually), the plugin registers your site with the server and receives credentials.</li>
<li><strong>Event publishing</strong>: when a trigger fires (e.g. a post is saved), the plugin sends an encrypted, HMAC-signed HTTP request to the server.</li>
<li><strong>Realtime connections</strong>: logged-in users’ browsers connect to the server via WebSocket or SSE to receive events.</li>
</ul>
<p>Event payloads are AES-256-GCM encrypted before leaving WordPress. The WPSignal server relays ciphertext and never has access to plaintext message content. Data is delivered in realtime and is <strong>not persisted</strong> on the server.</p>

WordSocket

WebSocket relay for WordPress. Realtime events plus a Yjs sync provider for WordPress 7.0 collaborative editing. No polling, no custom server.

POTAR

<p>Mesh-Plug provides a simple shortcode that connects to your MQTT broker over WebSocket and prints incoming messages to a live log.</p>
<p>Shortcode: [mesh_plug]</p>
<p>Map shortcode options:<br />
– map_tiles=”voyager|osm|light|dark” (default: voyager)<br />
– map_zoom=”13″ map_min_zoom=”2″ map_max_zoom=”18″<br />
– fit=”1|0|once” fit_max_zoom=”13″ center=”lat,lon”</p>
<h3>External services</h3>
<p>Mesh-Plug can connect to external services depending on how you configure and use it.</p>
<h4>MQTT broker (configured by the site administrator)</h4>
<p>Mesh-Plug connects directly from the visitor’s browser to the MQTT broker WebSocket URL you enter in Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> Mesh-Plug.<br />
This is required for the plugin to receive and display Meshtastic/MQTT messages.</p>
<p>Data sent: the visitor’s browser establishes a WebSocket connection to your broker; it may send a client ID and (optionally) the username/password you configured; it subscribes to the topic filter you configured.<br />
When: whenever a page containing the [mesh_plug] shortcode is loaded and the user connects (or auto-connect is enabled).</p>
<p>Terms/Privacy: this depends on the broker provider you choose. If you use a third-party MQTT hosting provider, review their terms and privacy policy.</p>
<h4>Map tile providers (CARTO / OpenStreetMap)</h4>
<p>If you use the Map tab, Mesh-Plug downloads map tiles from a free provider to render the basemap.<br />
By default, Mesh-Plug uses CARTO Voyager tiles. You can switch to OpenStreetMap tiles with shortcode map attributes.</p>
<p>Data sent: standard HTTP requests for map tiles; this typically includes the visitor’s IP address, user agent, and the requested tile coordinates.<br />
When: whenever the Map tab is opened/visible and the map needs to load tiles.</p>
<p>CARTO basemaps: https://carto.com/basemaps<br />
OpenStreetMap tile usage policy: https://operations.osmfoundation.org/policies/tiles/<br />
OpenStreetMap privacy policy: https://osmfoundation.org/wiki/Privacy_Policy</p>
