Microsoft's GitHub Under Siege As SpaceX's Cursor Takes The AI Stack

GitHub's long-standing dominance as the central code host is under scrutiny following a major outage that coincided with Cursor's (now SpaceX-owned) launch of Origin, its new code hosting platform. Origin aims to disrupt the industry by providing an integrated pipeline, from editing to deployment, specifically designed for the increasing role of AI agents in writing and managing code. This strategic move by AI companies to own core infrastructure challenges the traditional reliance on single vendors. While Origin is in beta with unreleased data terms, its emergence prompts businesses to re-evaluate their development stack dependencies and consider a future where AI agents drive software creation at unprecedented speeds.

And the question was “Where to store your company’s code?”

You wrote it, you put it on GitHub, and you got on with your day. The engineering teams treated it like plumbing that was essential, invisible, and never on the agenda.

GitHub has over 180 million developers worldwide, with a new user joining every second and over 630 million total repositories. Over 90% of Fortune 100 companies use the platform.

This week Cursor asked a question the industry has been avoiding. What happens when developers stop thinking of GitHub as the center of Software Development?

On Monday, Cursor opened the beta of Origin, its own code hosting platform, to paid users.

GitHub picked that same morning to have one of its worst days in recent memory. A global degradation dragged on for six hours and 42 minutes, pushing error rates nearly 20% percent across pull requests, issues, and the API and nearly 50% percent to archive and raw downloads. Cursor did not plan the timing. The outage made Origin’s argument better than any launch post could.

If you have never touched a repository, here is the short version.

A code host is the shared filing cabinet for software. It stores every version of a project, tracks who changed what, and gives teams a place to review each other’s work before it goes live.

GitHub, owned by Microsoft, is that filing cabinet for most of the world’s developers. It has recorded 257 incidents between May 2025 and April 2026, according to analysis by Incident tracking data, and its own chief technology officer acknowledged the platform was not built for the scale it is now being asked to handle.

The breaking story is that AI companies no longer want to sit on top of existing developer infrastructure. They want to own it. Cursor already controls the editor where code gets written. It bought the code review startup Graphite in December 2025 for an undisclosed price which reportedly went above its last valuation of $290 million.

Now it controls where code lives. Per the Cryptonomist, Origin launched with day- one integrations with Vercel, Depot, and Buildkite, the companies that handle deployment, builds and testing, which means Cursor is assembling the entire pipeline, not one link in it.

The logic makes sense once you see who is really pushing the code.

Origin is built for an era where software agents are writing much of the code themselves, making changes at a frequency human-centered platforms were never designed to absorb.

The logic makes sense once you see who is really pushing the code. At Cursor itself, roughly 35% of the merged pull requests are now written by autonomous agents. Origin is built for an era where software agents are writing much of the code themselves, making changes at a frequency human centered platforms were never designed to absorb.

If your agent writes the code, reviews the code and ships the code, the company that owns your agent wants to own the pipeline too. Cursor now sits inside SpaceX after a reported $60 billion all stock acquisition, which puts real capital behind that ambition.

Before anyone declares a changing of the guard, look at what the adoption data will show over the next two quarters. Origin is a beta, gated to paid Cursor users and it rolled out opt out by default, no opt in and its retention, residency and data training terms are still unpublished.

That means some companies’ developers may already be hosting proprietary code on a SpaceX-owned platform whose data terms do not exist in writing yet.

Enterprises do not move their filing cabinet on a bad outage day. Watch whether Origin publishes governance terms and whether GitHub’s incident count keeps climbing. Those two numbers will tell you if this is a moment or not.

Ask your engineering team one question this week about GitHub and other repositories. If our code host disappeared for 7 hours, what would stop?

Then map out which vendors own multiple layers of your development stack.

Concentration is convenient right up until it is a dependency.

Whether GitHub stays the center of software development will be decided by the companies asking these questions now, and discovered by everyone else.
