GitHub’s 2025 Report Reveals Some Surprising Developer Trends

GitHub released its Octoverse 2025 report last week. The platform now hosts over 180 million developers globally. If you are not familiar, Octoverse is GitHub's annual research program that tracks software development trends worldwide.

It analyzes data from repositories and developer activity across the platform.

This year's report shows TypeScript overtaking Python and JavaScript as the most used programming language, while India overtook the US in total open source contributor count for the first time.

Octoverse 2025: The Numbers Don't Lie

The report takes in data from September 1, 2024, to August 31, 2025, to paint an accurate picture of GitHub's fastest growth rate in its history. More than 36 million new developers joined the platform in the past year. That is more than one new developer every second on average.

Developers pushed nearly 1 billion commits in 2025, marking a 25% increase year-over-year (YoY), and monthly pull request merges averaged 43.2 million, marking a 23% increase from last year. August alone recorded nearly 100 million commits.

Let's dive into the highlights right away! 👇

630 Million Projects

GitHub now hosts 630 million total repositories. The platform added over 121 million new repositories in 2025 alone, making it the biggest year for repository creation.

According to their data, developers created approximately 230+ new repositories every minute on the platform.

Public repositories make up 63% of all projects on GitHub. However, 81.5% of contributions happened in private repositories, indicating that most development work happens behind closed doors.

Open Source's Focus on AI

Six of the 10 fastest-growing open source repositories (by contributors) were AI infrastructure projects. The demand for model runtimes, orchestration frameworks, and efficiency tools seems to have driven this surge.

Projects like vllm, cline, home-assistant, ragflow, and sglang were among the fastest-growing repositories by contributor count. These AI infrastructure projects outpaced the historical growth rates of established projects like VS Code, Godot, and Flutter.

India Rising...But Not as Contributor (Yet)

India added over 5.2 million developers in 2025. That's 14% of all new GitHub accounts, making India the largest source of new developer sign-ups on the platform. The United States remains the largest source of contributions. American developers contributed more total volume despite having fewer contributors.

India, Brazil, and Indonesia more than quadrupled their developer numbers over the past five years. Japan and Germany more than tripled their counts. The US, UK, and Canada more than doubled their developer numbers.

India is projected to reach 57.5 million developers by 2030. The country is set to account for more than one in three new developer signups globally, continuing its rapid expansion trajectory.

Six Languages Rule the Repos

Nearly 80% of new repositories used just six programming languages. Python, JavaScript, TypeScript, Java, C++, and C# dominate modern software development on GitHub. These core languages anchor most new projects.

TypeScript is now the most used language by contributor count. It overtook Python and JavaScript in August 2025, growing by over 1 million contributors YoY. This growth rate hit 66.63%.

Python grew by approximately 850,000 contributors, a 48.78% YoY increase. It maintains dominance in AI and data science projects. JavaScript added around 427,000 contributors but showed slower growth at 24.79%.
