OpenAI is developing its own code-hosting platform to compete directly with Microsoft’s GitHub, according to reporting from The Information on March 3, 2026. The move creates an awkward situation: Microsoft owns GitHub (acquired for $7.5 billion in 2018), holds approximately 27% of OpenAI, and has invested $13 billion in the partnership. The trigger? GitHub experienced 37 outages in February 2026 alone, leaving OpenAI engineers unable to commit code for hours at a time.
If commercialized and bundled with OpenAI’s Codex AI coding agent, this would mark an unprecedented competitive strike against one of the company’s biggest backers. Just one week after both companies issued a joint statement reaffirming their partnership, this news reveals the tensions simmering beneath the surface.
GitHub’s Reliability Crisis Is Real
GitHub’s stability has deteriorated sharply over the past year. The platform experienced 37 incidents in February 2026 alone, representing a 23% increase in incident frequency year-over-year. In the first half of 2025, GitHub logged 109 total incidents—up 58% from 69 in the same period the previous year. Seventeen were classified as “major,” totaling over 100 hours of disruption. At one point in 2025, uptime fell below 90%, violating service level agreements.
The outages aren’t minor annoyances. On March 3, GitHub.com request failures hit approximately 40%, with API failures reaching 43%. Two days later, Actions degraded so severely that 95% of workflow runs failed to start within five minutes. Developer Aakash Gupta tweeted: “GitHub had 37 incidents in February 2026 alone. Incident frequency is up 23%. Uptime dropped below 90% at one point in 2025. And GitHub is having another outage right now, today, as this story drops.”
The root cause? GitHub’s ongoing migration from its legacy data center to Microsoft Azure, which began in October 2025. As of February 2026, traffic is split between the two infrastructures—a transition that has introduced instability at the worst possible time. For OpenAI engineers, these outages don’t just delay work. They halt CI/CD pipelines, prevent commits, break webhooks, and stop AI coding agents like Codex from functioning.
Competing with Your Biggest Investor
The strategic implications are stark. Microsoft doesn’t just own GitHub—it’s OpenAI’s largest investor and cloud infrastructure provider. On February 26, 2026, both companies issued a joint statement reaffirming their partnership amid investor concerns about OpenAI’s $110 billion funding round led by Amazon. The statement emphasized “deep collaboration and shared success.”
One week later, The Information revealed OpenAI is building a GitHub competitor. Sources inside both companies paint a different picture. According to GeekWire’s investigative reporting: “There are people inside both companies that hate this thing. There are people inside Microsoft that don’t like it. There are people inside OpenAI that don’t like it.”
The project is still early-stage and “likely months away from completion,” according to The Information. Employees have discussed selling access to OpenAI customers, though the platform could remain internal-only. If OpenAI does commercialize this—particularly bundled with Codex—it would directly cannibalize Microsoft’s GitHub revenue and challenge one of the company’s flagship developer products.
OpenAI’s Play to Control the AI Development Stack
This isn’t just about reliability. OpenAI is positioning to control the entire AI development lifecycle: AI models (GPT-5.4), coding agents (Codex), and now code hosting. The platform would integrate tightly with Codex, enabling AI-native workflows where agents commit code, review pull requests, and manage repositories as first-class users—not just assistants.
Consider OpenAI’s recent moves. GPT-5.4 supports up to 1 million tokens of context with native computer-use capabilities. Codex agents can now “work in parallel across projects, completing weeks of work in days.” A proprietary code-hosting platform would complete the stack: developers could use OpenAI models, let Codex agents write and commit code, and host everything on OpenAI’s infrastructure. One vendor, end-to-end.
Tech Startups reports OpenAI is seeking “tighter control over how developers build, store, and deploy AI-driven applications.” The vision is compelling: GitHub wasn’t designed for AI agent-driven development. OpenAI’s platform could be. However, it also raises vendor lock-in concerns. Teams using OpenAI’s models, Codex, and code hosting may find switching prohibitively expensive later.
Timeline and Reality Check
Temper expectations. The project is in “early stages” and “probably won’t be completed for months,” according to The Information. There’s no firm commitment to commercialization. OpenAI could decide the project is too risky politically—straining the Microsoft relationship further—or strategically difficult given GitHub’s network effects with 100 million developers.
Even if OpenAI ships a commercial product, success isn’t guaranteed. GitHub’s ecosystem—Actions, Packages, integrations with every CI/CD tool—took 15 years to build. Developers trust GitHub with production code. Will they trust OpenAI, especially given concerns about AI training on private repositories? The platform could remain internal-only, serve only OpenAI API customers, or never launch at all.
But the fact that OpenAI is even exploring this signals serious dissatisfaction with GitHub’s reliability and Microsoft’s control. Whether or not the platform ships, the message is clear: OpenAI wants strategic independence.
What This Means for Developers
For developers, this creates uncertainty. GitHub dominates with 100 million users and 90% of Fortune 100 companies, but reliability issues are pushing teams to evaluate alternatives. GitLab holds 29% cloud market share with strong DevOps integration. Bitbucket serves 21% of the market, particularly in Atlassian shops. Self-hosted options like Gitea and Codeberg are gaining traction for critical infrastructure.
OpenAI’s entry could fragment the market further—teams spread across GitHub, GitLab, OpenAI, and self-hosted options, making collaboration harder. Or it could consolidate AI-focused development onto one platform. The risk is betting on vaporware. The opportunity is competition forcing GitHub to improve reliability and innovation.
Don’t make platform decisions based on unshipped products. But watch GitHub’s uptime closely. If incidents continue at February 2026 levels, OpenAI won’t be the only company exploring alternatives.
Key Takeaways
- OpenAI is building a GitHub competitor triggered by 37 outages in February 2026, exposing deep tensions with Microsoft despite public partnership statements
- GitHub’s reliability has deteriorated sharply: 109 incidents in H1 2025 (up 58% YoY), with uptime falling below 90% during Microsoft Azure migration
- OpenAI aims to control the entire AI development stack—models, coding agents, and code hosting—potentially displacing GitHub for AI-native workflows
- The project is months away and may never commercialize, but signals OpenAI’s push for strategic independence from Microsoft infrastructure
- Developers should monitor GitHub reliability but avoid switching based on vaporware—competition may improve GitHub faster than alternatives materialize
