Participants will have the opportunity to:
Build projects using open-source software and open-weight AI models
Collaborate with fellow developers and community members
Learn from maintainers, contributors, and experienced builders
Showcase projects and demos
Participate in official Hacktoberfest challenges
Receive Hacktoberfest swag and prizes (subject to availability)
Before You Apply
Hacktoberfest Hack Day Mumbai is a curated, hands-on build event focused on Open-Source AI

Building a new project
Contributing to an existing Open Source project
Developing with Open-Source AI
Collaborating with other participants
Taking part in project demos and showcase activities
Due to limited capacity and strong community interest, applications will be reviewed to ensure a balanced mix of first-time builders, contributors, maintainers, and professionals.
Submitting an application does not guarantee attendance.
