Contributing to Langflow
Hello there! We appreciate your interest in contributing to Langflow. As an open-source project in a rapidly developing field, we are extremely open to contributions, whether it be in the form of a new feature, improved infra, or better documentation.
To contribute to this project, please follow a "fork and pull request" workflow. Please do not try to push directly to this repo unless you are a maintainer.

🚩GitHub Issues
Our issues page is kept up to date with bugs, improvements, and feature requests. There is a taxonomy of labels to help with sorting and discovery of issues of interest.
If you're looking for help with your code, consider posting a question on the GitHub Discussions board. Please understand that we won't be able to provide individual support via email. We also believe that help is much more valuable if it's shared publicly, so that more people can benefit from it.
-
Describing your issue: Try to provide as many details as possible. What exactly goes wrong? How is it failing? Is there an error? "XY doesn't work" usually isn't that helpful for tracking down problems. Always remember to include the code you ran and if possible, extract only the relevant parts and don't just dump your entire script. This will make it easier for us to reproduce the error.
-
Sharing long blocks of code or logs: If you need to include long code, logs or tracebacks, you can wrap them in
<details>and</details>. This collapses the content so it only becomes visible on click, making the issue easier to read and follow.
Issue labels
See this page for an overview of the system we use to tag our issues and pull requests.
Local development
You can develop Langflow using docker compose, or locally.
We provide a .vscode/launch.json file for debugging the backend in VSCode, which is a lot faster than using docker compose.
Setting up hooks:
make init
This will install the pre-commit hooks, which will run make format on every commit.
It is advised to run make lint before pushing to the repository.
Run locally
Langflow can run locally by cloning the repository and installing the dependencies. We recommend using a virtual environment to isolate the dependencies from your system.
Before you start, make sure you have the following installed:
- Poetry (>=1.4)
- Node.js
Then, in the root folder, install the dependencies and start the development server for the backend:
make backend
And the frontend:
make frontend
Docker compose
The following snippet will run the backend and frontend in separate containers. The frontend will be available at localhost:3000 and the backend at localhost:7860.
docker compose up --build
# or
make dev build=1
Documentation
The documentation is built using Docusaurus. To run the documentation locally, run the following commands:
cd docs
npm install
npm run start
The documentation will be available at localhost:3000 and all the files are located in the docs/docs folder.
Once you are done with your changes, you can create a Pull Request to the main branch.
