Publish and subscribe to Salesforce Platform Events via the Pub/Sub API SF PubSub Client is a developer tool for Salesforce engineers to publish and subscribe to Platform Events directly from the browser — no external tools, no CLI, no setup. AUTO-CONNECT Click the extension icon while on any Salesforce tab and it automatically detects your active session. No credentials to type. PUBLISH EVENTS Select any Platform Event topic, enter a JSON payload, and publish instantly. Built-in JSON formatter keeps your payload clean. SUBSCRIBE & REPLAY Subscribe to live events or replay retained events from a specific replay ID. Events appear in real time with expandable cards showing full payloads and replay IDs. BROWSE ALL TOPICS Discover all Platform Events, Change Data Capture events, and Platform Event Channels in your org from a searchable list. VIEW SUBSCRIBERS See all active Apex trigger, Flow, and Process subscribers for your org's event topics. DIAGNOSTIC LOG A live connection log shows every auth step, handshake, subscribe, and publish — making it easy to debug event delivery issues. SECURE BY DESIGN All API calls go directly to your own Salesforce org. No data is sent to any third-party server. Session tokens are stored only in your browser's local storage. Works with Developer, Sandbox, Scratch, and Production orgs.
