Flowise

Flowise is a low-code, visual builder for LLM apps and AI agents. Instead of hand-writing orchestration, you drag nodes onto a canvas and connect them into chains, agentic systems, and retrieval-augmented (RAG) flows — its homepage positions it plainly as "Build AI Agents, Visually," an open-source agentic-systems development platform.

It targets developers and technically-minded builders who want to prototype and ship LLM features fast without wiring every model call, memory store, and tool by hand. Run it locally with one npm command, self-host the Apache-2.0 core on your own infrastructure, or use the managed Flowise Cloud. Because every flow is exposed as an API and an embeddable widget, Flowise fits an AI-assisted workflow as the visual layer between a model provider and a real product surface.

Highlights

• Drag-and-drop flow builder — assemble logic visually on a canvas, inspect each node's input/output, and iterate without redeploying code.
• Agents, RAG, and chains as nodes — build multi-agent systems, retrieval pipelines over your documents, and tool-using chains from composable building blocks.
• Self-hostable with an API — own the deployment, then call any flow over its REST API or drop in the embed widget to put it in an app.
• Large integration ecosystem — connect many model providers, vector stores, document loaders, and tools, so flows reach real data and services.

In an AI-assisted workflow

Flowise sits between your model provider and your product: build a flow visually, test it on the canvas, then call its endpoint from your app. Spin it up locally in seconds:

npx flowise start
# open http://localhost:3000

Good to know

License matters here. The Community Edition is Apache-2.0 — permissive enough to self-host, modify, and use commercially, including running it as a service. A separate Enterprise Edition ships inside the repo's /enterprise directory under a commercial license and stays inactive without a license key, so confirm which edition you're deploying before building a SaaS on it. Flowise Cloud is the paid managed path (a free tier plus paid plans starting around $35/month — verify current pricing on the official site). For how it stacks up against other visual builders, see Best AI App Builders (2026).
