Omarchy is blowing up. I've never been involved with anything in my career that has grown this fast. With Ruby on Rails, we had years to build solid institutions, teams, and relationships. With Omarchy, we've been forced to figure it all out in twelve days. It's exhausting, but also incredibly exciting. It was never sustainable with just Ryan and me running everything. That's how it was, more or less, up until Quattro. Lots of other contributors, but all the responsibility was on us to make sure the ship stayed afloat, the servers didn't crash, and fixes got pushed out quickly. Now it's time to build a proper institution. Durable, resilient, and competent. That's what we're doing here on Basecamp now. I'm spinning up teams for every facet of responsible distro management, and I'm getting an absolute outpouring of interest for all of them. Everyone wants to be part of this. We're winning hearts, minds, and volunteers at an astounding rate. Great! We need all of it to succeed. Because make no mistake: There are many people who'd love to see this rocket blow up before it reaches the moon. Aggrieved Linux users who don't like the sudden attention their exclusive hobby has received. Competing Linux distributions that are seeing our numbers explode. Mac stans who've sunk their identity into an apple. And, of course, any of the haters I've picked up in my quarter-century career speaking bluntly on the internet. They're not going to succeed. Because we've already become unstoppable. There's too much momentum, too much money, and too much support now backing this effort. We're living the Mandate From Heaven meme at the moment. And we are here to fulfill the prophecy: The Year of Linux on the Desktop! That has been a joke for two decades. But by the end of the year, nobody at Apple or Microsoft is going to be laughing. They're going to be scrambling. Because neither of these proud organizations currently has any method to counter the speed, vision, or ambition with which we're going to accelerate into the future of personal computing. This is the moment. This is the opening. This is our chance. For thirty years, we've been subject to one OS overlord or another. Dictating how we compute. Choking off competitors through platform malfeasance. Tollboothing the distribution. That ends now. Because Linux is going to win. And Linux is free. As in beer, speech, and source. But just because it's inevitable doesn't mean it's going to be easy. We have a lot of work in front of us if we actually want to make our mark. But there's never been a better time for this kind of delusional ambition. The age of agents is the unlocking factor. It sounds like a LinkedIn slogan, but it's true. Where the application of tokens goes, the innovation follows. We can fix everything. Let's do it together. Let's go. --- This is what I sent to the dozens of new volunteers who've signed up for teams within the new Omarchy organization yesterday. But we might as well broadcast our mission and intentions to the world too.
@dhh
See, here's the thing. I don't have any major problems with Apple products. Quality may have slipped on the software side recently, but ok, things happen. New guy in charge soon, maybe that turns around. And their hardware is undeniably great. I still enjoy using Apple products, and I'm cheering Apple on. The industry benefits when Apple's at the top of their game. But also... Omarchy is super interesting and super good. I try to be a curious person, and Omarchy presents an opportunity for me to stretch my curiousity, crack some habits, and try a novel different approach on for size. Linux!? I never thought. But here I am, and I'm here for it. I mean this is what we ask our HEY and Basecamp customers to do. Try something new! Be open! Be curious! We don't make software like everyone else. Our products don't look or work like anyone else's. We have a very different point of view than the mainstream. And those open to shedding their perception of what they think they need, are always in for a treat when they walk through our doors. I've essentially been following the Apple way for 40 (!) years. Maybe it's time for a break? Omarchy feels good for my brain! And I really like it! Getting more and more used to it every day. It's now my primary computer. The Macbook is sleeping, clamshell closed, under a pile of papers. The Dell XPS 16 w/ Omarchy is bright and alive. I'm writing this on it right now. I try to live my life by a few simple principles. One of those is to Like More Things. I wish that for you too.
@jasonfried
I don't think people truly understand just how determined I am at making Linux succeed on the desktop.
@dhh
I have never tried Omarchy so far but there are a few reasons why I think what DHH is trying to do with Linux on the Desktop could be significant. There is the right mix of AI help with many boring and costly tasks (drivers for instance), MacOS dropping in quality, and the fact the only reason why Linux never succeeded in the Desktop is that UX requires an opinionated development path from some entity able to also fuel it, not the distributions setup Linux historically had. For all this reasons, a few starts aligned, so this could be the right time. Also ROCm / Vulkan / CUDA GPU hardware options are evolving, and could end creating a compelling alternative to Apple hardware for local inference: but this is also the major risk, if Apple wins the local inference hardware battle, MacOS could become a forced choice for many.
@antirez
The Omarchy Core Team has been formed. It includes @ryanrhughes, @tobi, @iamdothash, @hancore_linux, @SpencerGBull, and yours truly. Pouring the foundations for a durable distro that can go the distance. Firmitas, utilitas, venustas! https://omarchy.org/news/2026/09/the-omarchy-core-team/
@dhh
Something I routinely am in awe about is the compute amplification every commit has today vs. 20 years ago, at least personally. Back then, my personal computer was only non-idle when I was working locally. I ran tests locally. When I pushed, there was no CI. The tests themselves were minimal maturity (simple unit tests, some e2e). Today when I push, CI exists. It fans out to 200+ jobs across macOS, Linux, and Windows that take ~20 minutes to complete in totality. A successful CI triggers ~8 beefy machines for tip releases. Tip releases trigger Apple notarization machines. Simultaneously, I have dedicated machines running 24/7 doing fuzz testing at basically 100% CPU constantly. Locally, my computer is using CPU much more of the day due to background agents. My average CPU utilization on my M4 Max overnight the last 7 days was over 20%. "Low" but before my average would've been 0% (deep sleep)! Plus, those agents are commanding a ton of GPU utilization elsewhere. I'm not making any judgement here of whether this is good or bad, because I think there are both good elements and bad elements. Simply that its quite astonishing how much compute my daily work amplifies in 2026 vs. 2006.
@mitchellh
It was the right call by @dhh to move Omarchy to use Quickshell, it is a delight to use, very happy I just migrated from waybar to it, so much more polished and pretty. Only took me a few hours to build this.
@samsaffron
I'm so happy Apple pissed off @dhh to the degree that he is now going on a decade long vendetta. 2026 is the year of Linux on my desktop.
@mschoening
I've updated my list of hardware recommendations for Omarchy. We really are spoiled with some killer options now! The Dell XPS 14/16 is my top laptop pick and the Framework Desktop my top desktop pick. https://learn.omacom.io/3/omacom/74/good-linux-hardware
@dhh
Linux adoption among programmers is about to go parabolic. Any missing app can be recreated easily. The open-source advantage with agents is unstoppable. Nobody is going to be waiting for Apple to sign their shit. Just keep a Mac Mini as a remote builder for iOS work. Done.
@dhh
Fair warning: Omarchy is leaning fully into the future and the age of agents. This is how we truly democratize Linux, bring the malleable OS to all, and capture as much of this newfound intelligence as possible. If that's not your jam, there's a lot of anti-AI distro options ✌️
@dhh
Hey fellow linux lovers, shouldI I install omarchy over my ubuntu lniux server on my spare ssd?
@BlockedPaths
New native Codex app for Linux looking great on Omarchy. Good job, @OpenAI! We'll have it hosted on the OPR and available for immediate install in Quattro.
@dhh
Great to see Dell collecting their well-deserved accolades for the XPS 13. And doubly so that YouTube reviewers are now focusing so much on Linux compatibility! The XPS 13 is a great choice for an Omarchy terminal/agent deck. https://www.youtube.com/watch?v=A2B7oI0FYqo
@dhh
I have over 40 Claude agents/subagents running right now and my Framework desktop is barely breaking a sweat. Machine is a beast but the real star is Linux. I am so tired of MacOS for dev 🙃
@theo
Claude Desktop is now available on Linux (Ubuntu and Debian) in beta. Alongside the browser and terminal, you now get a first-class desktop experience with Claude Code, Claude Cowork, and chat on all paid plans.
@ClaudeDevs
