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.
Within Copilot Workspace, developers can brainstorm, plan, build, test, and run code in natural language. This new task-centric experience leverages different Copilot-powered agents from start to finish, while giving developers full control over the process.
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 Copilot Agent Mode (Preview) is the autonomous coding feature in VS Code Insiders. Copilot plans, codes, runs tests, and fixes errors – all driven by your natural language requests.
BreveTest lets testers run end-to-end API tests using simple natural-language inputs. Just add one dependency and write a .breve file with credentials, API URL, request type, and expected results. No coding, no frameworks. What’s new? A fast, human-readable testing format that turns intent into executable tests. Unit testing in natural language is coming next.
