The Best AI Agent For Omarchy In 2026: Five Agents Ranked, Then The Models To Run Behind Them

The best AI agent for Omarchy in 2026 is Hermes Agent, the free open-source agent from Nous Research, and Omarchy installs it for you with one command.

Claude Code is my second pick because Omarchy supports it more deeply than any other agent, and OpenCode is third because it is free and works with any model provider.

Omarchy is DHH's Linux distribution built on Arch and Hyprland, and it ships with launchers for the major AI agents already wired in.

I run Omarchy in a virtual machine and I built an Omarchy desktop tab into my Agent OS, but I have not run a head-to-head agent test on Omarchy.

So this ranking comes from my daily use of these agents, plus the Omarchy manual and each tool's official Linux docs as they read today.

I'll give you the ranked list first, then how each agent works and how to start it, then the limits, and finally the real bench scores for the models you can run behind them.

The top three AI agents for Omarchy at a glance

• 🥇 Hermes Agent is the best overall, because it is free, it remembers what it learns and it does far more than write code.
• 🥈 Claude Code is the best for serious coding, and Omarchy gives it a usage panel and account switching.
• 🥉 OpenCode is the best free coding agent, because it lets you choose the model.

What Omarchy is and why the agent choice matters

Omarchy is a Linux distribution by DHH, based on Arch Linux, the Hyprland tiling window manager and the Quickshell desktop kit.

The project calls it "Beautiful, fun & agentic Linux", and the Omarchy site describes it as the OS for the age of agents.

It is free and MIT licensed, and the current version on the site is 4.0.4.

You install it from an ISO on a USB stick, or you try it first in a virtual machine.

It is a keyboard-driven desktop that leans heavily on the terminal.

That is why terminal-native agents suit it so well.

What Omarchy ships with for AI today

I read the AI page of the Omarchy manual today so that I would not have to guess.

The manual says every major coding-agent CLI comes pre-wired as a lazy-loaded launcher.

Nothing is downloaded until the first time you run one.

The list includes Claude Code, OpenAI Codex, OpenCode, Google Antigravity CLI, GitHub Copilot CLI, Crush, Grok Build, Pi, Oh My Pi, Ori, Muse Code and Cursor CLI.

Hermes is the exception, because choosing it installs Hermes Desktop.

The manual also says Omarchy does not pick a favourite for you.

So the only real decision left is which agent you set as the default.

How I ranked the best AI agent for Omarchy

I ranked every agent on four things.

The first is how well it fits a terminal-first workflow.

The second is how much support the Omarchy manual documents for it.

The third is what its official page says about cost.

The fourth is how much I rely on it in my own daily work.

None of this was measured on Omarchy, so the order is my honest opinion.

The five best AI agents for Omarchy, ranked

How each agent works and how to start it on Omarchy

1. Hermes Agent

Hermes Agent is the self-improving AI agent built by Nous Research.

It creates skills from experience, keeps memory across sessions, runs scheduled jobs and answers on messaging apps such as Telegram, Discord and Slack.

It is free and MIT licensed, and its README says you can use any model you want.

On Omarchy you run omarchy default agent hermes, or you choose Hermes Desktop under Install and AI in the Omarchy Menu.

The manual says both routes install Hermes Desktop plus a shared Hermes runtime, and that the first install takes a few minutes.

On other Linux machines, the Hermes README gives the one-liner curl -fsSL https://hermes-agent.nousresearch.com/install.sh | bash.

On Omarchy I would use the Omarchy route, because the manual says Hermes is only ever installed through the app there.

2. Claude Code

Claude Code is Anthropic's coding agent for the terminal.

The official docs say it requires a Pro, Max, Team, Enterprise or Console account, and that the free Claude plan does not include it.

On Omarchy you type claude and sign in, because the launcher is already there.

The official setup page gives curl -fsSL https://claude.ai/install.sh | bash for macOS, Linux and WSL.

Omarchy shows your Claude plan and usage limits in its agents panel, and it can switch between several Claude subscriptions.

3. OpenCode

OpenCode is an open source AI coding agent with a terminal interface.

Its docs say you can use any LLM provider by configuring their API keys.

On Omarchy you type opencode.

The OpenCode docs list curl -fsSL https://opencode.ai/install | bash and the Arch command sudo pacman -S opencode.

It is MIT licensed, and the manual says it follows your Omarchy theme.

4. Codex CLI

Codex CLI is OpenAI's coding agent that runs locally on your computer.

The repository is licensed under Apache-2.0, and OpenAI recommends signing in with a ChatGPT Plus, Pro, Business, Edu or Enterprise plan.

On Omarchy you type codex.

The Codex README gives curl -fsSL https://chatgpt.com/codex/install.sh | sh for Mac or Linux.

The Omarchy agents panel covers Codex as well.

5. Pi

Pi describes itself as a minimal, extensible agent harness that you can make your own.

It is MIT licensed, and you connect a subscription or an API key with /login.

On Omarchy you type pi.

The Pi README gives the installer curl -fsSL https://pi.dev/install.sh | sh.

Its README also says it skips features like sub-agents and plan mode on purpose.

The Omarchy commands every agent user should know

You set a default with omarchy default agent followed by the agent name, or in the Omarchy Menu under Setup, Defaults and Agent.

If the agent is not installed yet, choosing it installs it first.

The shortcut Super + Shift + Ctrl + A launches your default agent in a dedicated terminal window.

The command a runs the default agent inline in the current terminal.

The command omarchy agent prompt "Review this project" launches it straight into a task.

The shortcuts c, cx and cy start OpenCode, Claude Code and Codex directly.

The command omarchy update keeps the pre-wired launchers current.

The honest limits of running agents on Omarchy

The manual says agents launched through the default-agent shortcut run unattended in their don't-stop-to-ask modes.

It adds that you should be ready for them to actually do things.

The c, cx and cy shortcuts use auto-approving modes too.

So I would start in a project folder that holds nothing sensitive, and I would use the plain command when I want the agent to ask first.

Omarchy also ships an Omarchy Skill that teaches agents to tailor the system, and the manual calls it experimental.

The manual suggests plan mode first and names omarchy reinstall configs as the reset if an agent makes a mess.

Hermes has no instant launcher on Omarchy, and the manual does not name it in the usage panel.

Claude Code's official system requirements name Ubuntu, Debian and Alpine but not Arch, so I'd trust the Omarchy launcher there.

My own Omarchy testing is limited to a virtual machine, where Hermes has answered real prompts and created a real file for me.

Which Omarchy agent should you pick?

Pick Hermes Agent if you want one free agent for automations, research, content and code.

Pick Claude Code if you code all day and already pay for Claude.

Pick OpenCode if you want free software and your choice of model.

Pick Codex CLI if you pay for ChatGPT.

Pick Pi if you want something minimal.

The agent is only the body, so pick the brain

Here is the part most agent lists skip.

Hermes Agent, OpenCode and Pi do not ship their own model, because each one runs whatever model you connect.

Claude Code runs Anthropic's Claude models, and Codex CLI runs OpenAI's models.

So the same agent can feel brilliant or useless depending on the brain behind it.

GoldieBench scores those brains, and it does not score agents or operating systems.

Nothing below was benched on Omarchy, because I run the board from my own machines.

The scores still tell you how each model handles a hard one-shot build, which is the same kind of job you give an agent.

The Claude models behind Claude Code

These are live averages from the board on 14 October 2026, and each model link opens its full page.

The older Opus 5 scores higher than Opus 5.5 on my tasks, which is a good reason to check the board before you assume newest means best.

The OpenAI model behind Codex CLI

In my own Codex setup I run GPT-5.6 Sol, and its live average is 8.16 across 50 tasks on its model page.

That puts it just behind Claude Opus 5 on the same builds.

So if you already pay for ChatGPT, Codex CLI on Omarchy gives you a brain that scores near the top of my board.

Strong brains for Hermes Agent and OpenCode

Hermes and OpenCode let you choose the model, so these are the ones I would look at first.

For the Hermes-specific breakdown, read the best Hermes Agent model and the best LLMs for Hermes Agent.

Models from the other vendors Omarchy pre-wires

Omarchy also pre-wires Grok Build from xAI, Muse Code from Meta and Google's Antigravity CLI.

I have not ranked those agents, but I have benched a model from each of those vendors.

I can't tell you which model each of those agents runs by default on Omarchy, so please check each agent before you rely on these numbers.

Local models on Omarchy

The Omarchy manual recommends LM Studio and Ollama for running local models, and both install under Install and AI in the Omarchy Menu.

A local model keeps the whole setup free, but the board shows how wide the quality gap can be.

I ran all of these on my own Mac and not on Omarchy, so your speed on a Linux machine will depend on your hardware.

The local models board shows every local model I have run, and the best local model for Hermes Agent goes deeper.

You can also put any three models side by side on the compare page.

What GoldieBench does and does not tell you about an Omarchy agent

GoldieBench gives every model the same one-shot prompt to build a game, a page or a simulation, and then scores the rendered result from 0 to 10.

The methodology page explains exactly how each build is scored.

That maps well to the build jobs you hand an agent on Omarchy.

It does not measure how well an agent uses the terminal, how good its memory is or how well it fits Omarchy.

No agent on this list is on the board, because the board scores models.

So use the board to choose the brain, and use this ranking to choose the agent.
