Real Time Streaming Chat Interface With Websocket Support

via “real-time streaming chat interface with websocket support”

No-code LLM app builder with visual chatflow templates.

Unique: Implements token-by-token streaming at the execution engine level, where each node can emit partial results that are immediately sent to the client via WebSocket. The built-in chat UI supports markdown rendering, code highlighting, and custom formatting, with full streaming support from the first token.

vs others: Better UX than polling-based chat interfaces because streaming is push-based and real-time, and the execution engine supports streaming at every node (not just the final LLM). More integrated than building a custom chat UI on top of REST APIs because streaming is built into the core execution model.
