Hacktoberfest Repositories To Contribute To In 2025

Publish Date: Sep 29

Hacktoberfest is nearly here again. It's the perfect time to make your first open source contribution or give some love to your favorite projects. Whether you're new to coding or have years of experience, there's always a way to help.

I've put together a short list of repositories that are beginner friendly and fun to work on. I'd also love for you to share your own projects in the comments so others can discover them too.

🐍 Python Projects

If you like Python, here are a few cool projects that welcome contributions:

These are great for practicing your Python skills and building something useful at the same time.

🧰 Go and Dev Tools

Want to dive into Go or developer tooling? Check these out:

  • Diffium - A CLI tool that makes git diffs easier to understand. Super helpful if you work with AI coding agents.

JavaScript CLI Tools

  • pg-wire-mock - A mock PostgreSQL server for learning and hacking.

Both are great projects if you're into CLI tools and developer experience.

🌊 Laravel and SaaS

For PHP and Laravel fans:

  • Wave - A Laravel SaaS starter kit. You can help improve the docs, add translations, fix issues, or build plugins.

This one has an active community and is great for anyone building web apps with Laravel.

📚 Beginner Friendly Repos

These projects are great if you're just getting started. You can help by fixing typos, improving docs, adding examples, or tackling beginner issues.

All of these have a lot of small contributions that can make a big difference for new learners.


💬 Share Your Project

Hacktoberfest is all about collaboration and discovery. If you maintain a cool repo that people can contribute to, drop a link in the comments below. It doesn't have to be a big project. Even a small one with clear contribution guidelines can attract awesome contributors.

    Love this list. Hacktoberfest = that magical season when fixing a typo in docs makes you feel like a 10x dev. I’ll definitely check out Diffium & Wave and maybe finally stop being ‘README-only’ contributor 😂
