IDC09/2026Europe
A protocol that maintains a persistent, bidirectional connection between client and server. Both sides can send data at any time, making it suitable for chat and real-time updates.
Why it matters
Maintains an open, bidirectional channel: server and browser can send data to each other at any moment. Chat, collaborative editing, and live data work without refreshing.
What's missing without it
Without a persistent connection, updates require polling in a loop — delays increase, and servers face thousands of empty requests.
When it is used
Used for chat, notifications, collaborative editing, and anything requiring real-time two-way communication.
How we use it
AI assistant chat streams response tokens and tool status in real time.
