Flowise

Flowise is an open source agentic systems development platform that enables users to build AI agents visually. It provides modular building blocks for constructing systems ranging from simple compositional workflows to autonomous agents. Users can create multi-agent systems with workflow orchestration across multiple coordinated agents, or build single-agent chatbots with tool calling and knowledge retrieval (RAG) from various data sources. The platform supports human-in-the-loop review of agent tasks, full execution traces with observability tool integration (Prometheus, OpenTelemetry), and offers APIs, SDKs, and an embedded chat widget for extending and integrating into applications. Flowise supports over 100 LLMs, embeddings, and vector databases, and can be deployed on-premises or in the cloud with horizontal scaling via message queues and workers.
