[1/3] Octoverse 2025: A new developer joins GitHub every second as AI leads TypeScript to 1 (Category Engineering)
In late October, he appeared. The latest Octoverse report from GitHub, where the authors talk about the state of the OSS world (Open Source Software)More specifically, about the state of the software development ecosystem on GitHub. In 2025 The report shows record growth in the developer community. 2025 The impact of artificial intelligence tools on the process of development and choice of technologies.
But it is worth starting with the methodology, as it is not based on surveys, unlike many other similar reports. (What is good and allows you to assess what is really happening with repositories, code, developers): Source and period of data: the report is based on the analysis of all user activity on the GitHub platform for the period of time 1 September 2024 yearly 31 August 2025 (This is called the Octoverse Year.). Data obtained directly from events on the platform (commissions, pull request, issue, etc.) Primarily from public repositories, unless otherwise agreed. This approach made it possible to compare metrics year to year, taking into account seasonality. (Trends used to compare the same month 2024 and 2025). Coverage and sample size: this is great too – the Octoverse report draws on the entire population of developers on GitHub. 2025 year-round 180 millions (on 36 million more than a year earlier). Geographical representation: data reflect the global distribution of developers. The fastest growing community is in Asia and other emerging regions, with India coming out on top for adding developers. (more 5.2 yearly)It is also the second largest community. (right after). Industry representation: In the context of the report, any GitHub user associated with software creation is considered a developer. The report covers both open-source and corporate projects: 81,5Percent of all recorded deposits came from private repositories (internal development)more 63Percent of all GitHub repositories remain public or open source. In other words, the analysis takes into account both the day-to-day enterprise development and the large-scale open ecosystem on which it relies.
- Additional studies: The report is quantitative in nature, based on GitHub telemetry rather than questionnaires. However, the authors included point-based qualitative data, such as: series With developers about the practice of code revision to evaluate the usefulness of the new tool GitHub Copilot Code Review. The results of these interviews are embedded in the analysis, for example. 72,6% of respondents noted an increase in the effectiveness of code revision due to AI.
Now that it’s clear why the report is so interesting, it’s worth moving on to its findings and key findings.
👀 Key indicators of the Octoverse ecosystem 2025
- Total number of projects reached 630 Millions, AI projects. 4,3 Millions of developers and more 180 millions Number of public contributions (commits, PRs, gits, ...) - 1,12 billion, on average 43,2 Millions of pull requests per month (+23per cent) The most popular languages are TypeScript and Python.
These record numbers reflect major trends 2025 Unprecedented community growth and widespread adoption of AI technologies Well, post We will discuss the key results in more detail.
