Best Hack Built with GitHub Copilot
It’s time to turn your wildest ideas into reality faster than ever. Whether you’re trying a brand-new framework for the first time or cranking through complex logic, GitHub Copilot acts as your AI pair programmer to give you superpowers. So, what can you build with GitHub Copilot?
- Code from natural language: Describe what you want to build in a simple comment and watch Copilot generate a starting point.
- Learn technology on the fly: Use Copilot to explore a programming language, framework, or API you have never used before.
- Skip the tedious work: Generate boilerplate code, regular expressions, SQL queries, or unit tests so you can focus on the heart of your project.
Students get GitHub Copilot free through the GitHub Student Developer Pack — use mlh.link/GitHub for fast-tracked access. If student verification is still pending, you can use the available free tier or trial to start building.
Turn your idea into something real, and be sure to explain in your README or demo video how GitHub Copilot helped you build it.
