👋 Welcome to Langflow
Langflow is an easy way to build from simple to complex AI applications. It is a low-code platform that allows you to integrate AI into everything you do.
🚀 First steps
Installation
Make sure you have Python 3.10 installed on your system.
You can install Langflow with pipx or with pip.
Pipx can fetch the missing Python version for you, but you can also install it manually.
_10# Remember to check if you have Python 3.10 installed_10python -m pip install langflow -U_10# or_10pipx install langflow --python python3.10 --fetch-missing-python
Or you can install a pre-release version using:
_10python -m pip install langflow --pre --force-reinstall_10# or_10pipx install langflow --python python3.10 --fetch-missing-python --pip-args="--pre --force-reinstall"
Please, check out our Possible Installation Issues section if you encounter any problems.
We recommend using --force-reinstall to ensure you have the latest version of Langflow and its dependencies.
⛓️ Running Langflow
Langflow can be run in a variety of ways, including using the command-line interface (CLI) or HuggingFace Spaces.
_10python -m langflow run # or langflow --help
🤗 HuggingFace Spaces
Hugging Face provides a great alternative for running Langflow in their Spaces environment. This means you can run Langflow without any local installation required.
The first step is to go to the Langflow Space or Langflow 1.0 Preview Space
Remember to use a Chromium-based browser for the best experience. You'll be presented with the following screen:
From here, just name your Space, define the visibility (Public or Private), and click on Duplicate Space to start the installation process. When that is done, you'll be redirected to the Space's main page to start using Langflow right away!
Once you get Langflow running, click on New Project in the top right corner of the screen. Langflow provides a range of example flows to help you get started.
To quickly try one of them, open a starter example, set up your API keys and click ⚡ Run, on the bottom right corner of the canvas. This will open up Langflow's Interaction Panel with the chat console, text inputs, and outputs.
🖥️ Command Line Interface (CLI)
Langflow provides a command-line interface (CLI) for easy management and configuration.
