TL;DR.
Installing Langflow and Flowise involves setting up an environment using Miniconda, installing Node.js via NVM, and creating the necessary directories and scripts. Langflow, a user-friendly interface for LangChain, allows easy AI application creation with minimal coding. Flowise, an open-source platform for building AI workflows, supports extensive integrations and operates in secure environments. Both tools are designed to streamline AI application development but cater to different needs: Langflow is used for rapid prototyping and Flowise is used for customizable workflows. The choice between these tools depends on specific requirements like ease of use, customization, and deployment scope.

An Introduction.
Langflow and Flowise are are two AI tools that that serve different purposes. This means that using both tools expands my ability to create amazing AI experiences.
The purpose of this post is to describe the installation of Langflow and Flowise.
The Big Picture.
- Below is an image of the newly-installed Langflow UI:
- Below is an image of the newly-installed Flowise UI:
Combined, these tools provide a wide range of options when developing AI solutions.
Prerequisites.
Updating my Base System.
- From the (base) terminal, I update my (base) system:
sudo apt clean && \
sudo apt update && \
sudo apt dist-upgrade -y && \
sudo apt --fix-broken install && \
sudo apt autoclean && \
sudo apt autoremove -y
NOTE: The Ollama LLM manager is already installed on my (base) system.
What is Node.js, NPM, and NVM?
Node.js is a free, JavaScript (JS) server runtime. It runs JS code as single-threaded, non-blocking, asynchronous programs, which makes it very memory efficient. Node.js performs many system-level tasks, but is commonly used to run JS servers.
NPM (Node Package Manager) is the world's largest software registry. Open source developers use it to share packages with each other. Many organizations use NPM to manage private development as well. Most developers interact with NPM using the CLI (Command Line Interface), and usually ships with Node.js.
NVM (Node Version Manager) is used to switch between versions of Node.js. NVM works on any POSIX-compliant shell (sh, dash, ksh, zsh, bash) and runs on Linux distros, macOS, and Windows WSL.

Node.js must be installed (node -v) before continuing with this post.
Installing Node and NPM with NVM.
I open a terminal.
I install CURL:
sudo apt install -y curl
- I install the NVM (Node Version Manager):
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash
NOTE: The version numbers are listed on the NVM GitHub page.
source ~/.bashrc
- I use the NVM to install the LTS version of Node.js:
nvm install --lts
NOTE: The Node and NPM versions are listed on the screen.
- I make Node LTS the default NVM version, as listed in the previous command:
nvm alias default 20.12.2
- I confirm the Node installation:
node -v
- I confirm the NPM installation:
npm -v
What is Anaconda and Miniconda?
Python projects can run in virtual environments. These isolated spaces are used to manage project dependencies. Different versions of the same package can run in different environments while avoiding version conflicts.
venv is a built-in Python 3.3+ module that runs virtual environments. Anaconda is a Python and R distribution for scientific computing that includes the conda package manager. Miniconda is a small, free, bootstrap version of Anaconda that also includes the conda package manager, Python, and other packages that are required or useful (like pip and zlib).
http://www.anaconda.com/↗,
https://docs.anaconda.com/free/miniconda/index.html↗, and
https://solodev.app/installing-miniconda.
I ensure Miniconda is installed (conda -V) before continuing with this post.
Creating a Miniconda Environment.
- I use the
conda command to display a list of Miniconda environments:
conda env list
- I use
conda to create, and activate, a new environment named (-n) (Flow):
conda create -n Flow python=3.11 -y && conda activate Flow
NOTE: This command creates the (Flow) environment, then activates the (Flow) environment.
Creating the Flow Home Directory.
NOTE: I will now define the home directory in the environment directory.
- I create the Flow home directory:
mkdir ~/Flow
- I make new directories within the (Flow) environment:
mkdir -p ~/miniconda3/envs/Flow/etc/conda/activate.d
- I use the Nano text editor to create the
set_working_directory.sh shell script:
sudo nano ~/miniconda3/envs/Flow/etc/conda/activate.d/set_working_directory.sh
- I copy the following, paste (CTRL + SHIFT + V) it to the
set_working_directory.sh script, save (CTRL + S) the changes, and exit (CTRL + X) Nano:
cd ~/Flow
- I activate the (base) environment:
conda activate
- I activate the (Flow) environment:
conda activate Flow
NOTE: I should now, by default, be in the ~/Flow home directory.
What is Langflow?
Langflow is a user-friendly interface for LangChain, built using react-flow. It lets me easily create, and test, different setups by dragging and dropping components and using a chat box. Each part of the graph in Langflow works on its own. It's designed to help me quickly try out new ideas and build AI applications without needing to write much code. Langflow comes with ready-to-use components that I can mix and match to build AI apps. It fits perfectly with the tools I already use and makes it simple to develop basic, or advanced, AI applications. Langflow is all about making AI integration straightforward and expanding what I can do with AI in both tests and real-life uses.
https://docs.langflow.org/↗.
Installing Langflow.
- I use pip to install Langflow:
pip install langflow[local] -U --force-reinstall
langflow run
- Langflow is accessed using a browser:
http://localhost:7860/
What is Flowise?
Flowise is an open-source, low-code platform that helps me easily create customized AI workflows and agents. It simplifies the development of AI applications, which usually require many iterations, by allowing for quick changes from testing to production. Chatflows link AI models with various tools like memory, data loaders, and cache, along with over a hundred other integrations including LangChain and LlamaIndex. This setup enables the creation of autonomous agents and assistants that can perform diverse tasks using custom tools. I can build functional agents and OpenAI assistants, or opt for local AI models to save costs. Flowise supports extensions and integrations through APIs, SDKs, and embedded chat features. It is platform-agnostic, meaning Flowise can work with local, open-source AI models in secure, offline environments using local data storage. It is compatible with various platforms and technologies like Ollama, HuggingFace, AWS, Azure, and GCP, offering flexibility in deployment.
