Codex Community Hackathon - Hanoi
Codex Community Hackathon — Hanoi
The Codex Community Hackathon has arrived in Hanoi!
Join Codex Community Vietnam for a day of building with Codex. It's a hackathon for people who want to ship real AI products — not pitch decks. Form a team or build solo, then spend the day turning an idea into a working prototype.
Build something new from scratch or push an existing project further. Powered by Codex, OpenAI's coding agent, you'll run parallel tasks, experiment with Skills, and use worktrees to operate with greater speed and ambition.
This is a hands-on builder event designed to keep the room high-signal and focused on shipping.
Who This Event Is For
This event is for builders who want to ship something real:
Engineers
Startup founders and aspiring founders
Product builders
Indie developers
Whether you ship production code daily or you're newer to agentic software engineering, you'll find a place here — though some familiarity with coding tools is recommended.
How It Works
Build something meaningful with Codex. Over the course of the day you'll:
Form a team (up to 4 members) or build solo
Turn an idea into a functional prototype
Present your work to our judging panel
Projects can be B2B, B2C, consumer, agentic, infrastructure — or entirely weird. The only rule: it must be real, functional, and built during the hackathon.
Tracks
Eligibility: Tracks 1–3 require a new idea conceived during the event. Track 4 requires a product that's already live.
Track 1 — Market Scale: For products with serious business potential. Judges look for a large reachable market, a clear first customer, and a credible path to adoption.
Track 2 — Engineering Depth: For technically ambitious builds. Judges look for real engineering difficulty, strong execution, and creative use of Codex to ship something that would normally be hard to build in a day.
Track 3 — Impact to Vietnam: For products that create meaningful, Vietnam-specific impact. Judges look for deep understanding of Vietnamese users, culture, market behavior, and real-world adoption.
Track 4 — Best Use of Codex: For teams with an existing product, startup, or live business. Show how Codex and/or OpenAI models can transform your product, user experience, internal workflows, engineering velocity, or business model. Judges look for actual and deep transformations that not easily replicable by other Coding Agents or AI Labs' models.
Prizes
Tracks 1–3:
1st Prize: 12 months of ChatGPT Pro ($200) for every team member
2nd and 3rd Prize: 6 months of ChatGPT pro ($100) for every team member
Track 4:
1st Prize: $10,000 USD in OpenAI API credits
2nd Prize: $5,000 USD in OpenAI API credits
The best teams from each of the 3 tracks presents their product on stage.
Judges
To be announced. Our panel is being finalized and will bring together some of Vietnam's most influential voices in tech and business:
C-level leaders at major companies
Senior engineers with deep domain expertise
Active early-stage investors
Full lineup announced soon.
