What is Flowise?
Flowise is an open-source development platform for building AI agents and orchestrating large language model workflows through a visual interface. Its modular components support projects ranging from straightforward compositional flows to autonomous, coordinated agent systems. Developers can run Flowise through npm, use its hosted service, or deploy it within their own infrastructure.
The platform covers single-agent assistants, multi-agent workflows, retrieval-augmented generation, human review, and application integration. The official homepage currently states that Flowise is being sunset, so prospective users should review the linked announcement before adopting it for a new or long-term project.
Key Features
- Visual workflow builder: Connects modular components to create agentic systems and LLM-powered applications with less manual orchestration code.
- Single and multi-agent flows: Supports chat assistants as well as workflows distributed across multiple coordinated agents.
- Knowledge retrieval: Builds RAG experiences using content from formats such as PDF, DOC, HTML, CSV, Markdown, SQL, and JSON.
- Human review: Adds human-in-the-loop steps so people can inspect or provide feedback on work performed by agents.
- APIs and SDKs: Connects flows to other applications through an API, embedded chat widget, and TypeScript or Python SDKs.
- Deployment and observability: Supports cloud and on-premises deployment, execution traces, horizontal scaling, Prometheus, and OpenTelemetry.
Use Cases
- Build a chatbot that answers questions from documents or other connected knowledge sources.
- Coordinate specialized agents within a multi-step business or research workflow.
- Embed an AI assistant into an existing website or software product.
- Prototype and operate LLM applications with execution tracing and human approval steps.
