Anatomy of an open source project

Open source software thrives on collaboration. Contributors adopt various roles—writing code, managing releases, improving documentation—to ensure a project’s success. Whether you’re an experienced developer or new to open source, understanding these roles helps you make the greatest impact.

Core Roles in Open Source Communities

Role	Responsibilities	Example Actions
Author	Initializes the project; selects license; creates the first commit and repository.	Choose an MIT License; launch the repository on GitHub.
Owner	Holds legal rights; manages project governance and hosting.	Configure organization settings; delegate admin permissions; manage billing and domain names.
Maintainer	Reviews and merges PRs; enforces coding standards; organizes releases.	Use `git merge`; update CI/CD workflows; publish release notes.
Contributor	Submits code, documentation, bug reports, or support.	Open pull requests; report issues; write tutorials or translations.
Community Member / User	Provides feedback; reports bugs; helps others via forums and Q&A platforms.	Comment on issues; vote for features; assist newcomers on Stack Overflow.

Note

Roles often overlap. An author can also be a maintainer, and active users frequently evolve into contributors.

1. Author

The author (individual or organization) kick-starts the project by:

Selecting an open source license.
Creating and initializing the repository.
Publishing the first project announcement.

2. Owner

Owners hold legal authority and manage the project’s infrastructure. Key tasks include:

Managing billing, domains, and hosting.
Granting or revoking admin permissions.
Defining governance models (e.g., Benevolent Dictator For Life).

Warning

Ensure ownership agreements and licensing terms are clearly documented to avoid legal disputes.

3. Maintainer

Maintainers organize the codebase and oversee contributions:

Reviewing and merging pull requests.
Maintaining CI/CD pipelines.
Updating documentation and release notes.

Learn more in the GitHub Maintainer Guide.

4. Contributor

Contributors enhance projects through code, docs, bug reports, and more:

Fork the repository and submit pull requests.
Improve existing documentation or translate content.
Report and triage issues.

Contributor Workflow

# Clone the repository
git clone https://github.com/example/project.git
cd project

# Create a branch for your feature
git checkout -b feature/my-improvement

# Make changes, then commit and push
git add .
git commit -m "Add improved README section"
git push origin feature/my-improvement

5. Community Member / User

Users drive growth by:

Reporting bugs and suggesting features.
Voting and commenting on issues.
Helping others on forums like Stack Overflow.

Active community members often become contributors or maintainers as they deepen their knowledge of the codebase.
