Winners announced

Fri, Apr 17, 2026 - Vienna, Austria

Welcome to Vienna's first Codex Community Hackathon.

Join us for a day of building with Codex alongside our friends at Sentry.

This is a hands-on builder event designed for developers already comfortable with AI coding tools and production workflows.

Build directions include agentic coding tooling, AI-native interfaces, multimodal applications, domain agents, and eval tooling.

This event is organized by Alex Gavrilescu in his capacity as OpenAI Codex Ambassador.
