OpenAI Codex Community Hackathon - Bengaluru

About

​Join us for a focused morning of building with Codex. ​Build something new, improve an existing project, or experiment with agentic software-development workflows using Codex. Explore parallel tasks, Skills, worktrees, and other ways to build with greater speed and ambition. ​This is a hands-on community hackathon designed to keep the room collaborative, high-signal, and focused on shipping. ​Who this hackathon is for ​This hackathon is designed for developers and builders curious about Codex and agentic software engineering. ​No prior experience with Codex is required, although basic familiarity with software-development tools is recommended. We will begin with a short introduction to help everyone get started. ​How it works ​Participants may work individually or in teams of up to four members. ​You could: ​Start a new project from scratch ​Extend an existing or open-source project ​Prototype a developer tool or agent workflow ​Experiment with Codex Skills and parallel tasks ​Improve an existing project using Codex ​Given the limited build time, participants are encouraged to arrive with a project idea or an existing repository they would like to develop further. ​Suggested build directions ​Projects may explore areas such as: ​Agentic Coding: Developer tools and workflows that maximise leverage from Codex ​AI-Native Developer Experience: Interfaces and workflows designed around coding agents ​Domain Agents: Agents designed for specific industries or real-world constraints ​Multimodal Applications: Applications that work across text, images, audio, or other modalities ​Agent Evaluation: Tools for measuring, debugging, and improving agent performance ​Open Source: Contributions or improvements to existing open-source projects ​These are suggestions rather than restrictions. Participants are welcome to build in any direction where Codex plays a meaningful role. ​Project demos and judging ​Participants will have an opportunity to present what they built during a short project showcase. ​Each participating team should be prepared to share: ​A brief explanation of the problem ​How Codex was used ​A short product demonstration ​A GitHub repository or project link, where applicable ​Projects will be reviewed based on what was built, how meaningfully Codex was used, and the clarity of the final demonstration. ​Prizes ​To be announced soon. ​Venue and event partner ​This hackathon is being hosted with support from Dodo Payments, the billing and payments platform for AI-first and SaaS companies. ​Dodo Payments helps digital businesses sell across 220+ countries using 80+ currencies and 40+ local payment methods, while handling tax compliance, fraud, and chargebacks.
