Top 10 Open Source Projects for Beginners to Contribute To

Getting into open source can feel like showing up to a party where everyone already knows each other. You want to help, but where do you even start? The truth is, contributing early builds real skills — Git workflows, code review etiquette, reading unfamiliar codebases — that you just can’t get from tutorials. And the good news? There are tons of projects actively looking for beginner help.

Here are 10 beginner-friendly open source projects that welcome new contributors, with practical tips on how to get started.

1. first-contributions (GitHub)

Repo: https://github.com/first-contributions/first-contributions

This isn’t a real-world app — it’s a training ground. It walks you through forking, branching, committing, and opening a PR with a simple text file edit.

Why it’s great:

  • Zero coding required.
  • Step-by-step guide with visuals.
  • Instant feedback via automated checks.

Quick start:

git clone https://github.com/your-username/first-contributions.git
cd first-contributions
# Add your name to Contributors.md
git add Contributors.md
git commit -m "Add <your-name>"
git push origin main
Enter fullscreen mode Exit fullscreen mode

Then open a PR. Done. You’ve contributed.

2. The Odin Project

Repo: https://github.com/TheOdinProject/theodinproject

A free curriculum for learning web dev — built by the community, for the community.

Beginner tasks:

  • Fix typos in lesson markdown files.
  • Improve code examples.
  • Translate content.

How to find issues:
Look for labels like good first issue or content.

Example fix:

<!-- In a lesson file -->
- Use `const` for variables that won't be reassigned.
+ Use `const` for variables that won't be reassigned. Prefer it over `var`.
Enter fullscreen mode Exit fullscreen mode

Small edits matter — especially when thousands are learning from it.

3. Public APIs

Repo: https://github.com/public-apis/public-apis

A curated list of free APIs. No code, just Markdown.

Good for:

  • Learning Git basics.
  • Practicing PR etiquette.
  • Helping others discover tools.

Contribute by:

  • Adding a new API (with auth type, HTTPS, CORS).
  • Fixing broken links.

Example PR:

| API | Description | Auth | HTTPS | CORS |
|-----|-------------|------|-------|------|
| [JSONPlaceholder](https://jsonplaceholder.typicode.com) | Fake REST API | No | Yes | Yes |
Enter fullscreen mode Exit fullscreen mode

Check the PR template — they’re strict about formatting.

4. freeCodeCamp

Repo: https://github.com/freeCodeCamp/freeCodeCamp

One of the largest open source education platforms. Thousands of contributors.

Beginner paths:

  • Fix bugs in the learning platform (React/Node.js).
  • Update curriculum (Markdown).
  • Improve accessibility.

Pro tip: Run the app locally first:

git clone https://github.com/freeCodeCamp/freeCodeCamp.git
cd freeCodeCamp
# Install dependencies
pnpm install
# Start dev server
pnpm run dev
Enter fullscreen mode Exit fullscreen mode

Look for first-timers-only or help-wanted issues.

5. Zulip

Repo: https://github.com/zulip/zulip

Open source team chat app (like Slack). Python/Django + JavaScript.

Why it’s beginner-friendly:

  • Excellent contributor docs.
  • Friendly community.
  • Many small frontend/backend bugs labeled good first issue.

Example: Fix a typo in a button

// In frontend code
<button className="btn">
-  "Submit Resonse"
+  "Submit Response"
</button>
Enter fullscreen mode Exit fullscreen mode

They use GitHub workflows and have a live dev chat — ask questions freely.

6. Jupyter Notebook

Repo: https://github.com/jupyter/notebook

The tool millions use for data science. Python-based.

Beginner tasks:

  • Improve documentation.
  • Fix small UI bugs.
  • Write tutorials.

Tip: Start with type: docs or good first issue labels.

Even updating a docstring helps:

def save_notebook(self):
    """Save the current notebook to disk."""
    # Add error handling docs
    pass
Enter fullscreen mode Exit fullscreen mode

They use GitHub + Discourse for discussion.

7. VS Code (via Monaco Editor or Docs)

Repo: https://github.com/microsoft/vscode

You don’t have to touch the core editor. Start with docs or the website.

Easier entry points:

Example: Update a code snippet

<!-- In a markdown doc -->
Enter fullscreen mode Exit fullscreen mode


js
console.log("Hello World")

→ Add semicolon
Enter fullscreen mode Exit fullscreen mode


js
console.log("Hello World");

Enter fullscreen mode Exit fullscreen mode

They get tons of PRs — keep commits clean and focused.
