LangFlow Installation on Windows (via Docker Desktop)

Installing LangFlow with Docker Desktop was much more stable on Windows than installing Langflow OSS with uv or pip.

Prerequisites

1. Install Docker Desktop
   Download and install from the official site: https://docs.docker.com/desktop/install/windows-install

2. Run the installer (.exe file)

3. Log in or skip login
   You can optionally connect your GitHub account during setup.

Step-by-Step: Install LangFlow via Docker

1 - Create a project folder

mkdir langflow-docker
cd langflow-docker

2 -Clone the LangFlow GitHub repository

git clone https://github.com/langflow-ai/langflow.git
cd langflow

3 - Start Docker Desktop

Make sure Docker is running before proceeding.

4 - Start the Docker container

cd docker_example
docker compose up --build

After a few minutes, you'll see a success message like:
