In 2025, GitHub experienced unprecedented growth, with over 36 million new developers joining the platform, bringing the total to over 180 million. The introduction of GitHub Copilot Free in late 2024 significantly boosted developer sign-ups, coinciding with a surge in repository activity, pull requests, and code pushes. For the first time, TypeScript became the most used language on GitHub, surpassing both Python and JavaScript, illustrating a shift towards typed languages that enhance reliability in AI-driven coding environments. India emerged as a major contributor, adding more than 5 million developers, and is projected to account for one in three new developers by 2030. The adoption of generative AI tools has become standard, with 80% of new developers using GitHub Copilot within their first week, and more than 1.1 million public repositories now incorporating an LLM SDK. The open-source ecosystem thrived, with AI projects driving significant contributions, while enterprise-level collaboration predominantly occurred in private repositories. GitHub's data highlights a global shift in developer demographics and technological preferences, underscoring the increasingly diverse and AI-integrated landscape of software development.
