OpenAI is building a code-hosting platform to rival Microsoft’s GitHub, according to The Information’s report published March 3, 2026. The internal project stems from repeated GitHub outages that disrupted OpenAI engineers’ workflows—outages attributed to GitHub’s ongoing migration from legacy data centers to Microsoft Azure. Employees working on the project have discussed making it available to OpenAI’s customer base, which would mark a bold competitive move against Microsoft, which owns GitHub and holds a 27% stake in OpenAI.
GitHub Outages During Azure Migration Sparked Alternative
GitHub experienced major multi-hour outages in June 2025 and February 2026, with service disruptions attributed to the platform’s incomplete migration from legacy data centers to Microsoft Azure. On June 25, 2025, a “routine database migration” cascaded across Actions, repositories, and APIs, disrupting millions of developers. In February 2026, developers reported the web UI was “mostly unusable,” with inability to create or review pull requests and GitHub Actions failing across the board.
As of February 2026, GitHub traffic remains split between the legacy data center and Azure infrastructure—the migration that began in October 2025 is still incomplete. Azure itself experienced multiple outages in October 2025 and February 2026, affecting VMs and identity services for over 10 hours. These reliability problems affected OpenAI’s engineering teams and ultimately prompted the decision to build an alternative.
GitHub serves 180 million developers and 90% of Fortune 100 companies. When the platform goes down, the impact is global. For OpenAI—a company shipping AI products at breakneck speed—GitHub unavailability isn’t just inconvenient. It’s a business risk.
The Partnership Paradox: Competing with Your Investor
Here’s the irony: Microsoft holds approximately 27% of OpenAI on an as-converted diluted basis following the October 2025 restructuring. Microsoft invested over $13 billion in OpenAI ($11.6 billion funded to date). Microsoft also acquired GitHub for $7.5 billion in 2018. Now OpenAI is building a competitor to its investor’s multibillion-dollar acquisition.
This is rare in tech partnerships. Companies typically avoid competing in spaces where their investors have major stakes. Yet the OpenAI-Microsoft relationship has evolved significantly. Following the October 2025 restructure, OpenAI no longer has an exclusive Azure compute requirement. The company contracted $250 billion of Azure services but can also use other providers. OpenAI shares 20% of revenue with Microsoft, creating a complex web of financial interdependence.
Building a GitHub alternative signals strategic independence. It’s about reducing reliance on Microsoft infrastructure as much as solving technical problems. When your investor’s product repeatedly goes down and disrupts your engineering workflows, you have two choices: tolerate it or build your own. OpenAI chose the latter.
Early Stage Project with Uncertain Commercial Future
The OpenAI code-hosting project is in early stages and likely won’t be completed for months, according to The Information. Employees have considered making the platform available for purchase to OpenAI’s customer base, but no official commitment to commercialize it has been announced. It may remain an internal tool or launch as a commercial product—the decision appears unresolved.
If OpenAI does commercialize it, the company would enter the developer infrastructure market beyond just AI models. This would pit OpenAI directly against GitHub in a market with massive network effects and ecosystem lock-in. As Reuters coverage noted, “If OpenAI does sell the product, it would mark a bold move by the creator of ChatGPT to compete directly against Microsoft, which holds a significant stake in the firm.”
The most likely outcome is a limited enterprise offering for OpenAI customers rather than a mass-market GitHub alternative. OpenAI could differentiate through AI-native features—Codex-powered code review, intelligent merge suggestions, automated documentation—and integrate tightly with its API platform. However, displacing GitHub as the default code hosting platform would require overcoming enormous barriers.
Network Effects Make GitHub Hard to Displace
GitHub has 180 million developers, 630 million repositories, and 42% market share of AI coding assistants through GitHub Copilot. Every CI/CD tool, deployment platform, and security scanner integrates with GitHub. Switching costs are massive: migrating repositories, reconfiguring integrations, retraining teams, losing public repository visibility and developer portfolios.
Existing alternatives have struggled despite years of trying. GitLab offers comprehensive DevSecOps features and self-hosted options. Bitbucket provides Atlassian integration for enterprises. Gitea and Gogs serve teams wanting lightweight self-hosted solutions. None have seriously challenged GitHub’s dominance. Network effects are that powerful.
Even if OpenAI builds a technically superior product, convincing developers to switch requires overcoming ecosystem lock-in. However, the project still matters. It validates developer concerns about GitHub reliability during the Azure migration. It signals that major companies are willing to invest in alternatives when a platform’s availability becomes a business risk. And it adds competitive pressure on GitHub to complete the Azure migration and improve reliability.
Whether OpenAI’s platform remains internal or launches commercially, the message is clear: GitHub’s Azure migration problems are serious enough to justify building an alternative. For 180 million developers, that’s worth paying attention to.
Key Takeaways
- GitHub’s Azure migration (started October 2025, still incomplete February 2026) caused major outages in June 2025 and February 2026, disrupting millions of developers including OpenAI’s engineering teams
- OpenAI is building an internal code-hosting alternative with possible commercial release to customers—a rare case of a company competing with its investor’s $7.5 billion acquisition while the investor holds 27% stake
- The project signals strategic independence from Microsoft infrastructure despite the $13 billion partnership, highlighting tensions around service reliability and platform dependency
- Network effects make GitHub difficult to displace—180 million developers, 630 million repositories, and ecosystem lock-in create massive switching costs even if alternatives are technically superior
- Whether the platform launches publicly or stays internal, it validates concerns about GitHub reliability and creates competitive pressure to complete the Azure migration successfully
