Theo of t3.gg is building his own OS, t3os, and on Nov. 7 he told his followers to use Omarchy instead for now: “Omarchy has almost all the agent capabilities I am trying to bake in. It’s a really good choice for remote agents, and you should probably use it.” The post passed 186,000 views.
- t3os has no release date, but Theo says it’s still coming.
- His early computer-use benchmark had macOS at 27% and Omarchy and t3os at 100%. DHH’s reply: “A saturated benchmark is a bad benchmark. Bring it on!”
- Why not Ubuntu? “Too many permission issues and computer use edge cases on Ubuntu by default.”
- Caveat from Theo: Omarchy is “not optimized for headless usage,” but agents work around it.
My take
Take the numbers lightly. There’s no published task list, and t3os ties for first in Theo’s own test. But it matches what I see running my bots: a lean Arch box with sane defaults is easy for agents to drive. Omarchy 4.5’s agents panel now tracks 23 agents and providers.
God Bless, and May the Source Be with You!
