Comment ça marche

  1. Install Langflow

    Install it into a fresh environment with uv, per the README: uv pip install langflow -U (Python 3.10–3.13).

  2. Start the builder

    Run uv run langflow run and open http://127.0.0.1:7860 — the visual editor, playground and component library are all in the browser.

  3. Build, then deploy the flow

    Drag components into a flow, test it in the playground, then call it through the generated API endpoint or publish it as an MCP server.

// fonctionnalités

Pourquoi on l'adore

Visual flow building

Agents and RAG pipelines composed on a canvas from prebuilt components — prompts, models, tools, vector stores — each editable down to the Python.

Deploy as API or MCP

A finished flow becomes a REST endpoint, or an MCP server that other agents and tools can invoke directly.

Multi-agent orchestration

Flows can coordinate several specialised agents, with a playground for tracing each step before anything ships.

LangChain underneath

The component ecosystem is LangChain-based, so mainstream models, embeddings and retrievers are available without glue code.

Lancez-le vous-même

  1. Install with uv

    The README install path: uv is the recommended installer.

    uv pip install langflow -U
    uv run langflow run
  2. Run with Docker

    The official image, with an admin password set at first run.

    read -rsp "Langflow administrator password: " LANGFLOW_SUPERUSER_PASSWORD; echo
    export LANGFLOW_SUPERUSER_PASSWORD
    docker run -p 7860:7860 -e LANGFLOW_SUPERUSER_PASSWORD langflowai/langflow:latest
  3. Open the editor

    Once it starts, the whole builder runs in the browser.

Ce que vous pouvez créer

Automation is not only pipelines. PennyWise AI Tracker automatically reads the transaction SMS messages your bank sends and turns them into a trackable expense record, and Well promises the same spirit for household finance — "no more Sundays on Finance." Also on this shelf: bricks — Local, open-source Clay alternative for AI lead enrichment.

Questions fréquentes

Who makes Langflow?

The Langflow open-source project (langflow-ai on GitHub); it grew out of the Logspace team and is now stewarded with backing from DataStax/IBM.

Is Langflow free?

Yes — MIT licensed and fully self-hostable. You pay only for your own infrastructure and any model API keys you plug in.

Do I need to code?

No for standard flows — the builder is visual. Custom components are Python, and every built-in component can be opened and edited when you outgrow the defaults.

How does it compare to a well-known alternative?

Against n8n, Langflow is AI-first: its canvas is built around models, prompts and agents rather than app integrations. Against code frameworks like LangChain itself, it trades some flexibility for a visual builder and one-click API/MCP deployment.

How do I get started?

uv pip install langflow -U, then uv run langflow run and open http://127.0.0.1:7860.
