// como funciona

Como funciona

  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.

// recursos

Por que as pessoas gostam tanto

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.

Execute você mesmo

  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.

O que você pode criar

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.

// perguntas frequentes

Perguntas frequentes

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.
