David Heinemeier Hansson—better known as DHH, the 37signals co-founder behind the Omarchy Linux distro—has issued a public challenge to Microsoft. He wants the company to ship native versions of Office for Linux, and he’s asking CEO Satya Nadella directly to make it happen.
Posting on X, DHH wrote that “Microsoft should ship Office for Linux natively. Excel and Word are still the GOATs in their segments. What do we need to do to make this happen @satyanadella?”
It’s a straightforward ask, but it lands on a longer-running debate about whether Linux has ever truly been ready as a daily-driver desktop. DHH built Omarchy precisely to answer that question—an opinionated, pre-tuned Arch Linux-based desktop designed to strip away the endless terminal configuration that typically scares people away from the platform. But he acknowledges that productivity software remains the one gap holding Linux back.
The “last 10%” problem
Before Microsoft ships anything, DHH wants to be clear about what’s missing. The web version of Microsoft 365—the browser-based Office suite—already runs on Linux, and it’s free. But he says it still falls short by roughly “10% fidelity” for power users who depend on the full desktop experience.
That gap isn’t just cosmetic. According to Microsoft’s own documentation, the online versions of Word and Excel ship with fewer features than their desktop counterparts. The web apps are missing things like captions, citations, advanced collaboration tools, and document parts in Word alone. In other words, Microsoft has effectively confirmed the very gap DHH is pointing at.
Excel is where the case for a native port is strongest. Its advanced data-modeling engine, Power Pivot, doesn’t exist on the Mac version at all, according to Microsoft’s support answers. Power Query exists on Mac in a limited form. Neither comes close to matching the full Windows experience—and Power Pivot in particular supports DAX, relationships, and the kind of enterprise data modeling that makes Excel a staple for analysts.
Why Microsoft’s money no longer lives in Windows
DHH’s central argument is that Microsoft is no longer married to Windows as a business. He contends that the money comes from elsewhere these days, and Microsoft’s own financial results back him up.
In its FY2026 Q4 results, Windows OEM and Devices revenue fell 7% year over year. By contrast, Microsoft 365 Commercial cloud revenue grew 14%, Azure grew 43%, and total Microsoft Cloud revenue hit $59.3 billion, up 27%. Windows Latest estimated that Windows client revenue accounts for just over 5% of the company’s total, even as Windows still counts 1.6 billion monthly users.
The point isn’t that Windows is irrelevant—1.6 billion users is a massive base. It’s that Microsoft’s financial center of gravity has shifted to cloud and subscriptions, which makes DHH’s case far more plausible than it would have been a decade ago.
There’s also the counterargument that a native Office suite would cannibalize Windows sales. But much of Windows moves through OEM deals and enterprise agreements bundled with endpoint management, and a Linux user can still pay for Microsoft 365, Teams, Azure, or Defender. Microsoft doesn’t need you to buy Windows to make money off you.
The real moat is the ecosystem, not the interface
Matching Word and Excel’s interface is one thing; matching decades of document formats, calculation logic, macros, and edge cases is another. That’s why the internet’s common “just vibe-code Office for Linux” reply misses the mark. AI can replicate a UI, but replicating the full fidelity of complex workbooks takes far more.
The actual moat is the ecosystem wired into the apps: Power Query, Power Pivot, VBA, Power BI, SharePoint, OneDrive, Teams, and enterprise identity management. This is also why LibreOffice—while a legitimate alternative for most people—doesn’t eliminate demand for Microsoft’s version. Office remains the compatibility reference point for complex Excel workbooks and enterprise workflows.
Microsoft is already betting that its services should follow users wherever they are. It now officially supports Edge on Linux, and its Linux resources page pushes Edge, VS Code, PowerShell, and Defender to Linux users. It’s also optimized WSL so developers get Linux tooling without leaving Windows. The strategy is clear: win the subscription, not the operating system.
Is native Office for Linux realistic?
Linux has seen some real growth, though not the “10% of Windows market share” figure that circulated recently—that claim was proven inaccurate. Ubuntu is even growing faster through WSL on Windows 11 than as a native install, according to Canonical. But even so, Linux desktop usage is nowhere near large enough to make a native Office port an obvious business call for Microsoft.
Microsoft has announced no such plan. DHH’s request is strategically interesting, but it would still cost significant engineering time for a comparatively small desktop market.
What this means for you
For everyday Windows users, nothing changes today—there’s no new Office for Linux to install, and no announcement that one is coming. For Linux users who lean on Excel’s advanced features, the practical takeaway is that the web version is still your only official route, and it will keep falling short of the desktop experience until Microsoft decides otherwise.
If you’re a power user who can’t live without Power Pivot or VBA, you’ll likely want to stick with Windows (or run Windows workloads through WSL) for now. The good news is that Microsoft’s Linux support is expanding in other directions, so the gap may narrow over time even without a native Office suite.
What to do
Keep an eye on Microsoft’s official announcements—there’s no timeline to report. If native Office for Linux ever materializes, it would likely arrive through your existing Microsoft 365 subscription rather than a separate purchase. Until then, the web version remains the free, cross-platform option for basic Word and Excel work.
