GitHub recently published this year's Octoverse, the state of the open-source ecosystem.
Below are my key takeaways:
AI doesn t replace developers it brings more people into the ecosystem. A new developer joined GitHub every second in 2025. Top 5 developer populations: 1. United States, 2. India, 3. China, 4. Brazil, 5. United Kingdom.
Open source remains the foundation. Fastest-growing OSS projects by contributors include @Zen Browser, @VS Code, and AI-focused @Continue.
TypeScript is now the most used language on GitHub, overtook both Python and JavaScript. The AI effect? 80% of new repositories used just six languages: Python, JavaScript, TypeScript, Java, C++, and C#.
Gen AI is now standard in development. 1.1M public repositories now use an LLM SDK.
Agents are here. Coding agents created 1M+ pull requests (PR) in the last 6 months, and it's just getting started.
With GitHub Learning Lab, you’ll learn through issues opened by a bot in a GitHub repository. After you finish tasks, the bot will comment on your work and even review your pull requests like a project collaborator would.
GitHub CLI is a free and open-source command-line for GitHub.
It provides GitHub's graphical features like pull requests, issues, releases, etc. into a terminal. So, anyone can perform the whole GitHub operation from a terminal or with a script.
GitHub Mission Control is a unified command center that follows you wherever you work. It’s not a single destination; it’s a consistent interface across GitHub, VS Code, mobile, and the CLI that lets you direct, monitor, and manage every AI-driven task. With mission control, you can choose from a fleet of agents, assign them work in parallel, and track their progress from any device.
GitHub Copilot works alongside you directly in your editor, suggesting whole lines or entire functions for you. Powered by OpenAI its trained on billions of lines of public code, saving you time and helping you stay focused.
