Simplicity and Flexibility at its core.

Langflow is designed to redefine the boundaries of AI development in experimentation and real-world scenarios.

Prompt Variables

Dynamic inputs are introduced using curly brackets {}.

Fine-Tuning

Harness the full potential of LLMs by easily fine-tuning them from spreadsheets.

Group Components

Higher-level components naturally emerge from AI building blocks. Store and share your creations.

Custom Components

Go beyond the surface and code your own components.

Not just the UI.
Not just the Logic.

Langflow is a dynamic graph where each node is an executable unit. Its modular and interactive design fosters rapid experimentation and prototyping, pushing hard on the limits of creativity.

from langflow import load_flow_from_json

flow_path = 'myflow.json'
flow = load_flow_from_json(flow_path, build=False)


>> Graph:
>> Nodes: ['ChatOpenAI-vy7fV', 'LLMChain-UjBh1', 'PromptTemplate-5Qowg', 'ConversationBufferMemory-Lu2Nb' ]

>> Connections:
>> ChatOpenAI-vy7fV --> LLMChain-UjBh1
>> PromptTemplate-5Q0W8 -> LLMChain-UjBh1
>> ConversationBufferMemory-Lu2Nb --> LLMChain-UiBh1

And it's Python Based.

Python is the go-to language for data scientists. By being Python-native, Langflow leverages the most powerful data manipulation and machine-learning libraries out there.

Eeeeendless Components...

Discover the magic of composable building blocks. Pre-built components can be combined in numerous ways to create AI apps.

...with Powerful Integrations

Langflow is a no-code AI ecosystem, integrating seamlessly with the tools and stacks your team knows and loves.

    Explored @LangChainAI earlier this week & was blown away by its potential! 🚀 Then, I discovered @logspace_ai , making it a game-changer for low-code & no-code devs with a visual interface. 🤯

    This looks great. I think canvases are perfect for prompt chaining.

    Awesome! Got it up and running (the YouTube video was a bit easier on the eyes than the image on the README, btw). Kudos!
