[2/3] Octoverse 2025: A new developer joins GitHub every second as AI leads TypeScript to 1 (Category Engineering)
Continue. story yearly GitHub report on the state of the ecosystem Developing software on the platform, I will tell you more about its results.
📈 Unprecedented Community Growth
- The platform is more than full. 36 Millions of new developers are the highest absolute growth on record.
- Developers created around 121 Millions of new repositories per year (before 630 million)
- The number of commissions has almost reached 1 billion 2025 year (+25percentage 2024)
- Monthly merge of order. 43,2 Millions of pull requests (+23percentage 2024) This dynamic coincided with the launch of the free version of GitHub Copilot at the end. 2024It has attracted a wave of new users and projects.
🤖 AI has become an integral part of development Generative AI over the year has turned from a novelty into a standard developer tool.
- GitHub already has an order. 4,3 Millions of AI-related repositories (calculation through tagging repositories and highlighting part of the tags as related to AI projects).
- Above. 1,1 Millions of public projects use SDKs to work with large language models (LLM) - and 693 thousand They were created in the last few years. 12 months (growth178year-on-year) Beginners immediately implement AI in the work: almost 80Percent of new developers start using GitHub Copilot in their first week
All of this confirms that AI tools are now expected “by default” in the developer environment. The growth in the use of AI tools is accompanied by an increase in the contribution to code: a record was merged over the year 518,7 Millions of pull requests (+29% of the previous year)The total number of contributions to open projects has exceeded 1,12 billion (+13per cent).
🚀 TypeScript is out now 1place among languages For the first time in the last decade, the leader in the popularity of programming languages on GitHub changed: in August 2025 TypeScript Overtakes Python (The longtime leader of JavaScript) It became the most used language on the platform. The rapid growth of TypeScript is due to two factors.
- Modern front-end frameworks (React, Angular et al.) Generate project templates on TS by default
- Teams increasingly prefer strictly typed code when using AI: advanced TypeScript typing makes autogenerated AI code more reliable
During the year, the TypeScript community grew by1,05 million (+66per cent), while Python added ~850 thousand (+48per cent). Despite losing first place, Python remains a key language for AI and data science. 2,6 Millions of active contributors, and the Jupyter Notebook continues to serve as the primary environment for experimentation. (≈403 Thousands of repositories within AI projects). TypeScript and Python communities are now>5,2 million (near 3Percentage of active users of GitHub).
This shift confirms that AI influences not only the speed of coding, but also the choice of technologies - teams are more willing to trust AI-generated code to languages with strict typing, especially for production systems.
💯 AI is changing development preferences and practices Octoverse data points to a clear link between the adoption of AI tools and the evolution of the developer technology stack
- Starting with 2025 Python’s rise in popularity is almost parallel to JavaScript/TypeScript, indicating the universal impact of AI on ecosystems ranging from web development to data analytics. There are new approaches to working with code, such as "vibe coding" AI assistants have significantly lowered the entry threshold: if AI continues to simplify the creation of software, the number of people capable of “coding” may increase dramatically. On the horizon is the era of autonomous assistants (AI agents). There are already tools that can independently generate code, run tests and even open pull request for human verification.
In detention Let’s talk about the world of open source and the impact of AI on the productivity of development, as well as give conclusions.
