Automation Free tier (card may be required)
Documentation: pusher.com ยท Checked Sep 13, 2026
About
Pusher Channels is a hosted realtime messaging API that pushes events from your server to browsers and mobile apps over WebSockets, with automatic fallback for older clients. The free Sandbox plan includes 100 concurrent connections and 200,000 messages per day, which is plenty for development and small projects. Triggering events is one REST call or SDK method, and the debug console shows every event in real time. Note the sandbox is intended for non-production use.
