What is Flowise?
Flowise is an open source platform for building agentic AI systems. It offers modular building blocks that can be combined into simple compositional workflows or autonomous agents. The site describes two main approaches: Agentflow for multi-agent systems with workflow orchestration, and Chatflow for single-agent systems and chatbots that call tools and retrieve knowledge (RAG) from various data sources.
In practice you can build a visual flow, connect LLMs, embeddings and vector databases (the site mentions support for 100+ LLMs), upload documents such as PDF, DOC, CSV or Markdown, and add a human-in-the-loop step where a person reviews agent actions. Execution traces support Prometheus and OpenTelemetry for observability. The flows can be exposed through an API, a TypeScript or Python SDK, or an embedded chat widget, and deployed on-premises or in the cloud. The site notes that Flowise is being sunset.
