Flowise is an open-source visual builder for LLM apps, RAG pipelines, and multi-agent workflows that you can self-host for free or run on Flowise Cloud.
Flowise is an open-source visual builder for LLM apps, RAG pipelines, and multi-agent workflows that you can self-host for free or run on Flowise Cloud.
Flowise is an Apache-2.0 licensed visual LLM and agent builder. Drag-and-drop canvas for chains, RAG, and multi-agent flows on top of LangChain and LlamaIndex, with broad model and vector store support. Self-host free or run on Flowise Cloud. MCP client support is built in.
Strong bridge between low-code builders and developer-owned LangChain-style workflows. Main caution: The /pricing route redirected to sign-in during research, so pricing should be manually verified before publishing.
Build multi-agent systems with workflow orchestration distributed across multiple coordinated agents. Each agent can have its own tools, memory, and instructions, with handoffs between agents for complex task decomposition.
Build single-agent systems and chatbots with support for tool calling and knowledge retrieval (RAG) from various data sources. Supports document formats including TXT, PDF, RTF, DOC, HTML, CSV, MD, and SQL.
Allow humans to review tasks performed by agents within the feedback loop before final execution. This is critical for regulated industries and high-stakes decisions where AI outputs need human validation.
Full execution traces support Prometheus, OpenTelemetry, and other observability tools out of the box. Track every node execution, LLM call, tool invocation, and token usage across your workflows.
Extend and integrate to your applications using REST APIs, TypeScript and Python SDKs, and an embeddable chat widget. Deploy any chatflow as a /api/v1/prediction/:id endpoint with a single click.
