DevTools

In dev mode, the Vite plugin injects an in-browser overlay that shows active streams, RPC history, and connection status. Toggle with Ctrl+Shift+L.

The overlay is stripped from production builds. Disable it in dev with:

realtime({ devtools: false })

What you can see

• Active WebSocket connection state
• All RPC calls with timing, arguments, and responses
• Active stream subscriptions and their current values
• Published events flowing through topics
• Connection/reconnection events
