GitLab's AI hackathon ran from February to March 2026, attracting nearly 7,000 developers who built 600+ AI agents and flows on the GitLab duo Agent Platform. The $65,000 prize pool was split across multiple categories. The grand prize went to 'lore' (Living organizational Record Engine), an eight-agent system that captures institutional knowledge before it walks out the door with departing engineers. Other notable winners include gitdefender (automated security fixes in code review), graphdev (code impact mapping), and greenpipe (CI/CD carbon footprint analysis). A sustainability track rewarded projects that reduced compute costs and carbon emissions, with one project cutting costs 96% from $556 to $18/month. The next hackathon is planned with richer cross-project context capabilities.
