Codex Community Hackathon - Bengaluru
Join us for a day of building with Codex — OpenAI’s coding agent that helps you build and ship faster!
Bengaluru's first official Codex hackathon 🚀
This event is designed for developers who already use AI coding tools daily and are comfortable shipping production-grade code. No prior experience with Codex is required, but this is not an introductory workshop. Expect to hit the ground running fast.
Build something new from scratch or push an existing open-source project further with Codex. Spin up parallel tasks, use Skills, and leverage worktrees to operate at a higher level of velocity and ambition.
Attendance is capped (maximum of 4 members per team) to keep the room high-signal and deeply hands-on.
Please note that due to venue capacity, registration is subject to approval. Kindly complete the registration form with your accurate details, as incomplete or inaccurate submissions may not be admitted. If you intend to participate as a team, all members must register individually and receive approval separately.

Just a few quick reminders to help the day run smoothly:
1) Approval is on an individual basis
If you're attending as a team, each member needs to be registered and approved separately.
Because space is limited, we will only be able to admit approved participants.
Due to security measures, there will not be any on spot registrations and we cannot make any exceptions. Please do not arrive at the venue without approval.
2) Arrival timing
Registration opens at 9:00am, and we’ll begin at 10:00am sharp.
To keep things fair for everyone, check-in closes at 10:00am and we won’t be able to admit late arrivals.
3) In-person event
This is an in-person-only event.
If your plans change or you can’t arrive by 10:00am, we’d really appreciate you cancelling your spot so someone on the waitlist can join.
We do keep track of no-shows to help us plan future community events fairly.
