Flowise - Build AI Agents, Visually

What

Flowise is an open-source visual development platform for building AI agents, chat assistants, and agentic workflows. It is aimed at developers, technical teams, and organizations that want to design, test, and deploy LLM-based applications using modular building blocks rather than coding every orchestration step from scratch.

The product appears positioned between no-code/low-code workflow design and production-oriented AI application infrastructure. Its core workflow centers on visually composing single-agent chat flows or multi-agent systems, connecting models and data sources, adding human review where needed, and then exposing the result through APIs, SDKs, or embedded chat interfaces.

Features

• Visual agent and workflow builder — Provides modular building blocks to create anything from simple compositional workflows to more autonomous agent systems with a visual interface.
• Multi-agent orchestration — Supports coordinated multi-agent systems through Agentflow, which is useful for splitting complex tasks across specialized agents.
• Chat assistants with RAG and tool calling — Enables single-agent chatbots that can retrieve knowledge from multiple file and data formats and call tools to complete tasks.
• Human-in-the-loop review — Lets humans review tasks performed by agents, which can help teams add oversight to higher-risk or higher-value workflows.
• Observability and execution traces — Includes execution tracing and support for Prometheus, OpenTelemetry, and related tools to improve debugging, monitoring, and operational visibility.
• Developer and deployment support — Offers APIs, embedded chat, TypeScript and Python SDKs, plus cloud or on-premises deployment options with horizontal scaling via message queues and workers.

Helpful Tips

• Validate the visual builder against your target complexity — Flowise appears well suited for prototyping and productionizing LLM workflows, but teams should test whether its orchestration model fits their specific governance and reliability requirements.
• Map use cases to agent patterns early — Simple support or retrieval tasks may only need Chatflow, while more complex business processes may benefit from Agentflow and human review steps.
• Plan observability from the start — Since execution traces and telemetry support are available, teams should define logging, tracing, and failure-analysis practices before moving important workflows into production.
• Review deployment needs carefully — The site states support for both cloud and on-premises environments, so buyers should evaluate infrastructure, security, and scaling expectations in line with their internal policies.
• Confirm model and data-source fit during evaluation — Flowise supports many LLMs, embeddings, and vector databases, but specific implementation details for a given stack should be verified in documentation or testing.
