On June 4, 2018, Microsoft announced it had acquired GitHub for $7.5 billion—a deal that sent shockwaves through the tech world. The acquisition wasn’t just about buying a platform; it was about securing control over the backbone of modern software development. GitHub, with its 28 million users and 85 million repositories, wasn’t just a code-hosting service—it was the digital agora where developers collaborated, innovated, and built the future. The question of what company purchased GitHub wasn’t just about who wrote the check; it was about who would now shape the rules of open-source collaboration.

The deal was met with skepticism. Critics warned of Microsoft’s history of anti-competitive practices, while others saw it as a strategic masterstroke to bridge the gap between proprietary and open-source ecosystems. GitHub’s CEO, Nat Friedman, framed it as a way to "empower every developer on the planet," but the skepticism lingered. Was this a move to monopolize developer tools, or a genuine commitment to fostering open-source growth?

Five years later, the debate persists. Microsoft’s integration of GitHub into its Azure cloud services, the rise of Copilot (an AI-powered coding assistant), and the platform’s continued dominance in developer workflows prove that the acquisition wasn’t just a financial transaction—it was a pivot point in how software is built, shared, and monetized. Understanding what company purchased GitHub requires peeling back layers of corporate strategy, cultural resistance, and the evolving nature of open-source itself.

The Complete Overview of What Company Purchased GitHub

The acquisition of GitHub by Microsoft in 2018 was the culmination of years of strategic maneuvering. Microsoft, under CEO Satya Nadella, had undergone a transformation from a Windows-centric monopoly to a cloud-first, developer-friendly enterprise. GitHub, founded in 2008 by Tom Preston-Werner, Chris Wanstrath, and P.J. Hyett, had become the de facto standard for version control and collaboration. By 2018, it was clear that what company purchased GitHub would determine the future of developer tools—and Microsoft was the only player with the resources to compete with GitLab, Bitbucket, and other emerging platforms.

The $7.5 billion deal was the largest acquisition in Microsoft’s history at the time, dwarfing even its purchase of LinkedIn. The price reflected GitHub’s market dominance: 95 million developers used the platform monthly, and it hosted over 100 million repositories. But the real value wasn’t just in the user base—it was in GitHub’s role as the nervous system of open-source development. Microsoft’s bet was that by controlling GitHub, it could influence not just how code was written, but how it was deployed, scaled, and monetized in the cloud.

Historical Background and Evolution

GitHub’s origins trace back to 2007, when the original creators sought to make Git—a distributed version control system—more accessible. By 2008, the platform launched, offering free hosting for Git repositories with a web-based interface. Within a decade, it had become indispensable. Developers relied on GitHub for everything from open-source contributions to proprietary project management. The platform’s pull request system, issue tracking, and integration with CI/CD pipelines made it the default choice for teams worldwide.

Microsoft’s interest in GitHub predated the acquisition. In 2015, the company began hiring key GitHub employees, including CEO Nat Friedman, who had previously worked at Microsoft. The strategy was clear: Microsoft wanted to embed itself in the open-source ecosystem without alienating developers who distrusted its past. The acquisition was framed as a way to "preserve GitHub’s independence" while leveraging Microsoft’s cloud infrastructure. Yet, the move was also a response to Google’s Anthos and Amazon’s AWS, which were encroaching on GitHub’s territory by offering their own developer tools.

Core Mechanisms: How It Works

The acquisition wasn’t just about buying a product—it was about integrating GitHub’s infrastructure into Microsoft’s broader ecosystem. Post-acquisition, GitHub remained free for open-source projects, but Microsoft began bundling enterprise features with Azure. For example, GitHub Actions—now a cornerstone of CI/CD—was tightly integrated with Azure Pipelines. This allowed Microsoft to capture value from both the developer community and corporate clients migrating to the cloud.

Another critical mechanism was the introduction of GitHub Copilot, an AI-powered code assistant trained on public repositories. While Copilot sparked debates about licensing and copyright, it also demonstrated Microsoft’s ability to monetize GitHub’s vast repository of open-source code. The company positioned Copilot as a productivity tool, but its underlying model relied on GitHub’s data—raising questions about whether the acquisition was truly about empowering developers or extracting value from them.

Key Benefits and Crucial Impact

The acquisition of GitHub by Microsoft had immediate and long-term consequences for the tech industry. For developers, the biggest benefit was the continued free access to GitHub’s core features, including unlimited private repositories. For Microsoft, the acquisition provided a foothold in the developer tools market, which was previously dominated by open-source alternatives. The move also accelerated Microsoft’s shift from a Windows-centric company to a cloud and AI-driven enterprise.

Yet, the impact wasn’t without controversy. Some developers feared Microsoft would use its dominance to stifle competition or push proprietary solutions. Others saw the acquisition as a net positive, giving Microsoft a stake in the open-source community it had historically marginalized. The reality fell somewhere in between: GitHub’s growth continued, but Microsoft’s influence over its direction became undeniable.

"GitHub is where the world builds software, and Microsoft’s acquisition means they now have a direct line to every developer on the planet." — Nat Friedman, Former GitHub CEO
