Flowise

Open source drag and drop for LLM apps.

Visual and no code

Flowise is a self hosted canvas for building chatflows and agents. It ships an API and an embeddable widget, so a flow you build in the UI becomes something your product can call.

Reach for it when

  • You want a self hosted visual builder
  • You need an API and a chat widget out of the box
  • You are prototyping fast and iterating with others

Look elsewhere when

  • You want everything in version control
  • Your logic is better expressed in code

Common questions

Is Flowise free to use?

Flowise is open source and free to run yourself. You still pay whichever model provider you point it at, and this tutorial is free with no signup.

Do I need to know Python to use Flowise?

No. Flowise is built around a visual canvas, so you can get a working flow without writing code.

When should I not use Flowise?

You want everything in version control. Your logic is better expressed in code.

Lessons for Flowise are being written. Meanwhile the LangGraph tutorial covers the same ground: state, tools, loops, memory and human approval. Most of it carries straight over.
