Init Chat Engine – Real-Time, Community, Extensible

A lightweight, real-time community chat system built with REST API and Vanilla JS. No jQuery, no reload. Full admin panel with moderation tools.

wpsignal

WordSocket sends realtime events from your WordPress site to connected browsers. 
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).
On WordPress 7.0+, WordSocket also registers as a WebSocket-based Yjs sync provider for real-time collaborative editing in the block editor, replacing the default HTTP polling transport with a low-latency WebSocket connection.
Features:
<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>Real-time collaborative editing in the block editor (WordPress 7.0+, via Yjs sync provider)</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>
How it works:
<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>
This plugin connects to the WPSignal service at api.wpsignal.io for the following operations:
<ul>
<li>Site registration: 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>Event publishing: when a trigger fires (e.g. a post is saved), the plugin sends an encrypted, HMAC-signed HTTP request to the server.</li>
<li>Realtime connections: logged-in users’ browsers connect to the server via WebSocket or SSE to receive events.</li>
<li>Collaborative editing: on WordPress 7.0+, Yjs document updates are relayed over the same WebSocket connection.</li>
</ul>
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 not persisted on the server.
