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.
Reviewers mostly see GitHub as the default home for software work: reliable version control, clean pull requests, issue tracking, broad integrations, and strong CI/CD through Actions. Users repeatedly praise how it keeps teams organized, supports open source, and makes sharing, learning, and shipping easier. A few caveats come up: beginners can find Git workflows, Actions, and advanced settings confusing; support is seen as weak; and some mention pricing, slower Actions at scale, and AI-related concerns. Makers of TestSprite and others also credit its PR and automation infrastructure for real production workflows.
GitHub is fantastic because it seamlessly integrates version control, collaboration, and automation into one unified developer platform. It not only makes code sharing effortless but also enables teams to work transparently, efficiently, and at scale. The ecosystem around pull requests, CI/CD, code review, and community contributions elevates the entire development workflow and empowers engineers to build better software together.
vs Alternatives
We chose GitHub because it provides the most comprehensive and mature ecosystem for modern software development. Its seamless integration of version control, collaboration tools, CI/CD, security features, and open-source communities makes it the most reliable platform for teams of any size. GitHub’s user experience, extensibility, and strong community support allow us to develop, review, and ship software more efficiently than any alternative.
