🚀 Open Source Hack Day — Hacktoberfest 2026
BUILD. CONTRIBUTE. COLLABORATE.
Ready to go beyond tutorials and make something real?
Join us for a hands-on Open Source Hack Day where you'll learn how modern open-source development works, build with real technologies, collaborate through GitHub, and turn your ideas into working projects.
Whether you're making your first open-source contribution or already comfortable with Git and GitHub, there's a way for you to participate.
🧑💻 What You'll Experience
You'll work with real, organizer-maintained GitHub projects and learn the complete contribution workflow:
Explore → Understand → Build → Test → Pull Request → Review
Depending on your experience level, you'll tackle challenges involving:
Feature development
Bug fixing and debugging
Testing and reliability
Documentation
Security
Performance
Refactoring and code quality
The event is structured across five difficulty levels — Novice, Beginner, Competent, Proficient and Expert — allowing participants to take on challenges appropriate to their experience.
🔥 More Than Just Open Source Contributions
Hack Day also includes official MLH prize challenges, giving participants the opportunity to build and demonstrate projects using open-source and open-weight AI.
🏆 Best Open-Source AI Project
Build an original project where open-source or open-weight AI plays an important role.
💎 Best Use of Gemma 4

These challenges are part of the official Hacktoberfest Hack Day program and have their own eligibility, submission and judging requirements.
🌱 What You'll Learn
By the end of the event, you'll have practical experience with:
Git & GitHub
Open-source contribution workflows
Issues, branches and Pull Requests
Debugging and testing
Code review
Software development practices
Open-source and open-weight AI
Building and presenting working projects
