Flowise

Open-source visual builder for AI agents — drag, drop, and deploy LLM flows and chatbots.

What is Flowise?

Flowise is an Apache-2.0-licensed visual builder for LLM applications: drag nodes for models, prompts, memory, vector stores, and tools onto a canvas, wire them together, and deploy as chatbots, agents, or API endpoints. Built originally around LangChain's component ecosystem, it exposes hundreds of integrations — every major LLM provider, embedding model, and vector database — through configurable nodes, with newer releases adding multi-agent orchestration (Agentflows) and human-in-the-loop steps. Embedding is a strength: a generated script tag drops your assembled chatbot into any website, and REST APIs/SDKs serve programmatic use. Teams self-host via Docker (free, full control) or use Flowise Cloud from about $35/month. Compared to Dify's full-platform approach, Flowise is lighter and more component-flexible but expects more assembly; its permissive license also makes it the safer base for building commercial products on top.

FAQ

Is Flowise free?

Self-hosting is free under Apache 2.0. Flowise Cloud starts around $35/month for managed hosting with predictable limits.

Can I embed a Flowise chatbot on my website?

Yes — every chatflow generates an embed script you paste into any site, plus REST endpoints and SDKs for deeper integration.

Flowise or Langflow?

They're close cousins. Flowise (Node.js) leads on chatbot embedding and commercial-friendly licensing; Langflow (Python) appeals to Python teams and DataStax-ecosystem users.
