GitHub announced on January 25, 2023, that more than 100 million developers worldwide were using the platform—about two years earlier than its original 2025 target. That was a historical milestone, not a count of 100 million paying customers or monthly active professional programmers. GitHub’s 2025 Octoverse report later put its scale at more than 180 million developers, so the 100-million figure is best understood as the point at which GitHub’s developer network crossed a symbolic threshold.
What GitHub announced
GitHub CEO Thomas Dohmke announced that “more than 100 million developers” were using GitHub on January 25, 2023. The company had set a goal in 2019 of reaching 100 million developers by 2025, so it said the milestone arrived roughly two years early. The original announcement is available at GitHub’s company blog.
The wording matters: GitHub said more than 100 million, rather than exactly 100 million. It presented the figure as the size of its worldwide developer community, not as an independently audited census of software engineers.
What “100 million developers” does—and does not—measure
GitHub’s announcement does not fully publish a monthly-active-user methodology. The figure should therefore not be read as any of the following:

- 100 million full-time or professional programmers;
- 100 million people committing code every month;
- 100 million paying customers or paid seats;
- 100 million unique people who use no other code-hosting service; or
- 100 million contributors to public open-source repositories.
Later Octoverse reporting uses terms such as “global developer accounts” and “developers who build on GitHub.” GitHub’s 2023 analysis covered anonymized platform data from October 1, 2022, through September 30, 2023. That supports treating the headline as a platform-population metric, while leaving questions such as inactive accounts, multiple accounts, and the precise definition of “developer” unresolved. The methodology and period are described in GitHub’s 2023 Octoverse research.
How large is GitHub now?
The 100-million milestone is no longer GitHub’s latest reported scale. Its official 2025 Octoverse report says more than 180 million developers were building on GitHub, with more than 36 million joining during that year. GitHub described that as 23% year-over-year growth and said the average sign-up pace exceeded one new developer per second. Those are GitHub’s own 2025 measurements, not a real-time active-user counter; see the 2025 Octoverse report.
| Measure | Reported value | Qualification |
|---|---|---|
| Milestone | More than 100 million developers | Announced by GitHub on January 25, 2023 |
| Original target | 100 million by 2025 | GitHub said it arrived about two years early |
| 2023 growth | Nearly 26% increase in global developer accounts | Compared with the prior year in GitHub’s 2023 Octoverse report |
| Latest cited scale | More than 180 million developers | GitHub’s 2025 Octoverse report |
Why GitHub became so large
GitHub began as a convenient home for Git repositories, but its value comes from the workflow surrounding each repository. GitHub documents repositories, branches, commits, pull requests, issues, code review, and integrations as connected parts of the platform; its overview of Git is at GitHub Docs.
One place for collaboration
- Code hosting: Teams store source code, history, branches, and release artifacts.
- Review and planning: Pull requests, issues, discussions, and project tools organize changes before they reach production.
- Automation: GitHub Actions can run tests, builds, packaging, and deployment workflows.
- Security: Dependency information, secret scanning, and code-scanning features connect security checks to repositories and pull requests.
- Packages and integrations: Teams can publish packages and connect marketplace tools to existing workflows.
- Learning and reputation: Public repositories, documentation, and contribution histories give students, maintainers, and job candidates a visible portfolio.
Open source is important—but private development is larger
GitHub’s scale is often equated with public open source, yet its 2023 Octoverse report said more than 80% of activity was associated with private projects. GitHub also reported 301 million contributions to open-source projects during 2023. These figures describe different kinds of activity and should not be combined into a user count.
The practical conclusion is that GitHub serves two overlapping markets: public collaboration among maintainers and contributors, and private software delivery inside companies. Commercially backed projects attracted substantial contributor activity, while private repositories supported everyday product development that outsiders cannot see.
Enterprise adoption and Microsoft ownership
GitHub said 90% of Fortune 100 companies used the platform in 2023, and repeated a “more than 90%” figure in a 2024 announcement. Company adoption is not the same as paid seats, organization size, or universal use by every employee. The compliance context appears in GitHub’s enterprise governance article and its FedRAMP announcement.
Microsoft’s ownership gives GitHub access to a major enterprise, cloud, identity, and AI ecosystem, while GitHub continues to operate as a distinct developer-facing platform. That combination helps explain why the service can appeal both to an open-source maintainer and to a large organization with governance requirements. It does not prove that Microsoft ownership alone caused the user milestone.
Copilot and GitHub’s move into AI development
GitHub crossed 100 million developers during the rapid adoption of AI coding tools. Copilot expanded GitHub’s role from storing and reviewing code to assisting with code completion, explanation, debugging, and other development tasks. GitHub later said Copilot was writing nearly half of the code in files where it was enabled, while its 2023 research reported that 92% of surveyed developers were using or experimenting with AI coding tools.

They show that AI became part of GitHub’s broader platform strategy. In its 2025 report, GitHub said nearly 80% of new developers used Copilot within their first week.
GitHub also introduced GitHub Models, offering a model playground and connections toward Codespaces, Visual Studio Code, and Azure AI. Model availability, limits, and commercial terms change, so current details should be checked in GitHub’s Models announcement rather than assumed from its launch description.
What the milestone means for developers
Benefits
- A larger potential pool of collaborators, reviewers, maintainers, and employers.
- More examples, documentation, packages, and reusable open-source components.
- A familiar workflow for moving from an issue to a reviewed change, automated tests, and a release.
- Greater visibility for a public portfolio or open-source contribution history.
Responsibilities and risks
- Privacy: Check repository visibility, organization permissions, secrets, and branch protections before publishing code.
- Security: A popular platform still requires access control, dependency review, scanning, and incident response.
- AI review: Copilot suggestions need testing, human review, security checks, and license awareness; faster generation is not automatically better software.
- Concentration: Relying on one vendor creates exposure to outages, pricing changes, policy decisions, API limits, and moderation rules.
What it means for companies evaluating GitHub
The milestone demonstrates reach, not that every organization should buy a paid plan. Free access can suit individuals, students, hobbyists, and public projects. Teams may need organization administration and collaboration features, while larger companies may require enterprise governance, compliance, security, and support. Codespaces, Actions, Advanced Security, and Copilot can add separate usage or subscription costs; current allowances and prices should be verified on the official pages.
| Option | Typical fit | Check before committing |
|---|---|---|
| GitHub Free | Individuals, students, hobbyists, and public open source | Whether private collaboration, compute, or governance needs exceed included features |
| GitHub Pro | Individual professionals | Current allowances, plan inclusions, and Copilot terms at GitHub pricing |
| GitHub Team | Small and medium-sized engineering teams | Administration, security requirements, and Actions or Codespaces consumption |
| GitHub Enterprise | Large organizations with governance and compliance needs | Sales-led pricing, identity controls, data requirements, and support |
| GitHub Copilot | Teams seeking integrated AI assistance | Plan limits, data policies, model access, and review procedures at Copilot plans |
When an alternative may be better
- GitLab: Consider its integrated DevSecOps and hosted or self-managed options; compare at GitLab and GitLab pricing.
- Bitbucket: Its Jira and Atlassian integration can suit organizations already centered on that ecosystem; see Bitbucket and pricing.
- Azure DevOps: Azure-standardized enterprises may prefer its broader planning, pipelines, repositories, and testing tools; see Azure DevOps and pricing.
Self-hosting, data-residency rules, existing Atlassian or GitLab investments, cost structure, and vendor-diversification policies can outweigh GitHub’s network effects. No competitor’s user figure should be compared directly with GitHub’s without checking how each company defines accounts, activity, and customers.

The important fact is not simply that a counter passed 100 million. GitHub connects developers, repositories, employers, open-source communities, package ecosystems, automation, security tools, and AI services. Each additional participant can make the platform more useful to others, creating a network effect. The trade-off is greater dependence on one company’s infrastructure and rules.
For readers assessing GitHub as a tool or business platform, the sensible questions are practical: Which repositories must be public or private? What governance and security controls are required? How much Actions, Codespaces, or Copilot usage is expected? Can the organization export code and workflows if policies or prices change? Those answers matter more than the headline number alone.
