It supports Agentflows for multi-agent orchestration, Chatflows for single-agent RAG-enabled assistants, and HITL (Human-in-the-Loop) workflows. The platform exposes a REST API and TypeScript/Python SDKs, supports embedded chat widgets, and integrates with 100+ LLMs, embedding models, and vector databases. It offers full execution tracing with support for Prometheus and OpenTelemetry, and can be scaled horizontally using message queues and workers.
