Flowise

Flowise is an open-source, visual platform for building agentic systems and LLM-powered applications. It provides a drag-and-drop interface to create custom workflows, orchestrate multiple agents, and build conversational AI applications. Key features include support for tool calling, knowledge retrieval via RAG, and human-in-the-loop feedback. It enables users to integrate over 100 LLMs, embedding models, and vector databases. Flowise is designed for both cloud and on-premises deployment, scaling horizontally with message queues and workers. It also offers APIs, SDKs (Typescript & Python), and embedded widgets to extend and integrate applications. Observability is enhanced through execution traces, Prometheus, and OpenTelemetry support. Use cases include building chat assistants, multi-agent systems, and AI-powered features in existing platforms.
