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 see GitHub as the default place to manage code: strong for version control, pull requests, issue tracking, open-source discovery, and everyday team collaboration. Users repeatedly praise Actions and integrations for automating builds, tests, releases, and deployments, while also calling it reliable and easy to fit into existing workflows. Makers of TestSprite, Metabase, and Welltory reinforce that view, though specific detail mainly comes from TestSprite’s use of PR and Actions infrastructure. Main drawbacks: beginner learning curve, complex settings and permissions, uneven support, and some concerns about pricing, scale, and AI-related direction.
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.
