About this event
It’s that time of year again—GitHub Summerfest is back, bigger and better than ever! This year, we’re turning up the heat with an expanded format. In addition to our classic one-hour virtual event—featuring the latest news, live demos, expert Q&A, and plenty of GitHub swag—we’ve added two 45-minute sessions for deep technical dives.
When:
📅 June 18, 2025

Main stage (15:00 - 16:00 CEST)
- What’s new from GitHub
We’re kicking off GitHub Summerfest with the latest and greatest from GitHub, featuring updates around AI, compliance, and productivity.
- Artificial intelligence models for developers: Easy and free with GitHub Models
See how easy it is to experiment with top AI models from OpenAI, Mistral, Llama, Cohere and others. All you need is your GitHub account: just start GitHub Codespaces and start prototyping.
- From code to cone: Building a flavor-picking API with GitHub Copilot
Join us for a hands-on demo that showcases the power of GitHub Copilot. We’ll build a mood-based "ice cream matcher" API using Copilot, then integrate it with Copilot Chat for an interactive, personalized experience. . It’s a fun, tasty look at how Copilot can be enhanced with custom data to streamline development and create engaging, AI-driven experiences.
- Quiz time
Test your GitHub knowledge with a live quiz—and win some swag while you’re at it.
Stage B (16:00 - 16:45 CEST)
Modernizing legacy systems with GitHub for stress-free vacation
Aviation remains the safest way to travel, yet much of its software is considered legacy. Carefully maintained and state-of-the-art software stack is needed to aim for rock-solid reliability, ensuring safety and efficiency. Discover how GitHub can enable developers to modernize critical application systems in a modern world. For this case, Emmanuel will show how to leverage Copilot for AI-powered code understanding, test generation, and iteration; GitHub Advanced Security to detect and fix vulnerabilities with secret protection, code scanning, and dependency reviews; and finally, GitHub Actions to automate workflows for efficient, reliable software delivery.
Stage C (16:00 - 16:45 CEST)
Copilot agents: Vibe coding, fueled by MCP
We’re diving into GitHub’s agentic mode and showing how MCP (model-centric platform) takes Copilot agents to the next level. From initial setup to building full features in minutes, this demo showcases how MCP enables custom skills, multi-agent workflows, and real developer acceleration. You'll see what all the hype is about—and why combining Copilot agents with MCP isn’t just cool, it’s a game-changer. Whether you're building tools, automating workflows, or just here to vibe-code, this is where productivity meets summer energy.
