Problem

Designing with AI takes too many steps

You usually connect MCP servers and edit settings before the agent can touch your file.

The usual way
Omastrator on Omarchy
The Omarchy menu with Omastrator 0.2 Beta highlighted.
Open Omastrator
The command bar with the request: make 3 design variations of this page.
Press /
The agent's cursor, tagged Claude, works in the first variation.
The agent works in your file

With a default agent set in Omarchy

Agitate

Neither kind of tool feels right

AI-first tools do not feel like design tools. Established apps add AI on top of manual tools.

Solution

A real design tool with agents at its core

On Omarchy, Omastrator starts your default agent for you, already connected. No MCP setup. No settings.

Agent
Variation A, a design the agent drew as real frames and layers.
You
The Text tool caret in the headline of Variation A, where the designer types new words.

FAQ

Questions

Is it finished?

No. Version 0.2.3 is a beta. It installs as omastrator-beta next to 0.1. The two do not change each other's files.

Do I need Omarchy?

You need Arch Linux with pacman. Omarchy adds the bar pages and the menu entry, and starts your agent already connected. Without it, run claude mcp add omastrator -- omastrator-beta --mcp.

Which machines?

x86_64 and aarch64.

Which agents?

On Omarchy, the app starts your default agent for you, already connected: Claude Code, Codex, OpenCode or Gemini CLI, with the model you set in it. No MCP setup. No settings. Set a default agent in Omarchy first (Setup → Default → Agent); other agents open in a terminal. Manual setup is optional: omastrator-beta setup connects Claude Code or Gemini CLI sessions outside the app. For Codex or OpenCode, add omastrator-beta --mcp by hand.

What about privacy?

Your files stay on your computer. The app needs no account, sends no usage data, and goes online only for a Browser View site or a deploy you start. Your agent sends what it reads to its model provider.

How do I report a problem or an idea?

In the app, open the project menu and choose Report an issue or idea… You can also use the buttons in Feedback.

What does it cost?

The beta is free. Agent use counts against your agent plan.

Install

Install the beta

One line in a terminal.

curl -fsSL https://get.seanireton.com/omastrator | bash
Then
omastrator-beta setup

Read the script x86_64 package SHA-256 aarch64 package SHA-256

The script checks the SHA-256 sum and installs with pacman. Direct download: sudo pacman -U <file>

0.2.3 beta 5
