How to Contribute in OpenDevin?


1. Fork the Official Repository


Fork OpenDevin repository into your account. Clone your forked repository into your local environment.

git clone [email protected]:<YOUR-USERNAME>/OpenDevin.git

2. Configure Git


Set the OpenDevin official repository as your upstream to synchronize with the latest updates in the official repository. Add the original repository as an upstream

cd OpenDevin
git remote add upstream [email protected]:OpenDevin/OpenDevin.git

Make sure that the remote is set.

git remote -v

You should get both origin and upstream in the output.

3. Synchronize with the Official Repository


Synchronize the latest commit with the official repository before start coding.

git fetch upstream
git checkout main
git merge upstream/main
git push origin main

4. Create a New Branch And Open a Pull Request


Once you finish implementing, open the forked repository and locate the source branch, which is your new branch. The target branch is OpenDevin/OpenDevin main . Once you’ve found both branches, you should see a PR in OpenDevin PRs.

Then OpenDevin team will review your code.

PR Rules


1. Pull Request title


As described here, a valid PR title should begin with one of the following prefixes:

  • feat: A new feature
  • fix: A bug fix
  • doc: Documentation only changes
  • refactor: A code change that neither fixes a bug nor adds a feature
  • style: A refactoring that improves code style
  • perf: A code change that improves performance
  • test: Adding missing tests or correcting existing tests
  • ci: Changes to CI configuration files and scripts (example scopes: .githubci (Buildkite))
  • chore: Other changes that don’t modify src or test files
  • revert: Reverts a previous commit

For example, a PR title could be:

  • refactor: modify package path
  • feat(frontend): xxxx, where (frontend) means that this PR mainly focuses on the frontend component.

You may also check out the previous PRs in the PR list.

As described here, we create several labels. Every PR should have a better tag with corresponding labels.

2. Pull Request description


  • If your PR is small (such as a typo fix), you can go brief.
  • If it is large and you have changed a lot, it’s better to write more details.

How It Works




export OPENAI_API_KEY="..."
export WORKSPACE_DIR="/path/to/your/project"
python -m pip install -r requirements.txt
uvicorn opendevin.server.listen:app --port 3000

Then, in another terminal, execute this:

cd frontend
npm install
npm run start -- --port 3001

Now you can access OpenDevin from  localhost:3001

Choosing a Model


LiteLLM has been used in this tutorial, OpenDevin can run with any foundation model provided by LiteLLM, including OpenAI, Claude, and Gemini. For a full list of providers, you can visit LiteLLM’s website.

To change the model, set the LLM_MODEL and LLM_API_KEY environment variables.

For example, if you want to run Claude:

export LLM_API_KEY="your-api-key"
export LLM_MODEL="claude-3-opus-20240229"

OpenDevin Frontend


Getting Started with the OpenDevin Frontend


Available Scripts


In the project directory, you can run:

npm start


Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits.
You will also see any lint errors in the console.

npm run build


Builds the app for production to the dist folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.
Your app is ready to be deployed!



The OpenDevin terminal is powered by Xterm.js.

The terminal listens for events over a WebSocket connection. The WebSocket URL is specified by the environment variable REACT_APP_TERMINAL_WS_URL (prepending REACT_APP_ to environment variable names is necessary to expose them).

A simple websocket server can be found in the /server directory.
