FlowiseAI

FlowiseAI is an open-source, low-code platform for developers and businesses building customized LLM applications, AI agents, and agentic workflows with a visual drag-and-drop interface.

Key capabilities include:

• Visual builders for different complexity levels: Assistant (beginner-friendly chat assistants with tools and RAG), Chatflow (single-agent systems, chatbots, and advanced techniques like Graph RAG), and Agentflow (multi-agent systems and complex workflow orchestration).
• Broad model and data ecosystem support: works with 100+ LLMs, embeddings, vector databases, document loaders, tools, and data integrations for retrieval-augmented generation and knowledge-based assistants.
• Production operations and governance: tracing and analytics, execution logs and visual debugging, evaluations, human-in-the-loop, plus security controls such as RBAC, SSO, encrypted credentials, rate limiting, and restricted domains.
• Deployment and scale options: self-hosted and air-gapped deployments, cloud options, and vertical or horizontal scaling (including message queues and workers), with API, CLI, and SDK access and an embeddable chat widget.

Pricing: Freemium, open-source core with cloud services and enterprise plans.

Notable for combining a low-code visual editor with multi-agent orchestration and production features (monitoring, evaluations, and security controls). It is YC-backed and has been cited as a Challenger in the multi-agent systems and orchestration market alongside vendors such as Microsoft and LangChain.
