AUV means Application Use Via ....

Think of it as a programmable computer use, without agents.

Getting Started

Install

Install directly from GitHub:

cargo install --git https://github.com/moeru-ai/auv auv-cli --bin auv
auv --help

After installation, use the auv CLI directly:

auv --help
auv invoke --help

Setup

macOS

OS permissions are required to be granted to the process that launches AUV, usually your terminal app.

Open System Settings -> Privacy & Security and enable:

Permission Needed for
Accessibility AX tree reads, focused element control, keyboard/pointer automation.
Screen Recording Screenshots, OCR, visual inspection, and evidence capture.
Automation AppleScript/System Events app activation and foreground fallback paths.

After changing permissions, restart the terminal process and rerun:

auv doctor
auv invoke app.probePermissions

Understand AUV

For Cua, agent-browser, and similar computer-use projects, it is common to execute screenshot, read image, click, type, wait, and follow-up verification steps in sequence, then ask LLMs or agents to judge the next move.

flowchart LR
  A[Agent] --> B[screenshot]
  B --> C[read image]
  C --> D[decide next step]
  D --> E[click]
  E --> F[wait]
  F --> G[type]
  G --> H[verify]
  H --> D

Many of those repeated sequences can be squashed into reusable GUI operations. Opening an app, waiting for readiness, filling a form, and checking the result should be callable as one command instead of spending tokens on the same step-by-step loop every time.

Modern agents often use skills or project instructions to orchestrate tool calls, CLIs, and scripts. But built-in computer-use surfaces, such as OpenAI Computer Use or Claude Computer Use, are still primarily interactive model-tool loops, not scriptable GUI automation libraries.

Similar to Playwright, what if we could organize those actions into executable scripts, reusable?

}

AUV expects agents to write, test, and improve reusable GUI automation for E2E tests and rapid application actions.

In fact, AUV is not a computer-use agent. It does not ship an agent or harness. It offers tools, CLIs, drivers, and verifiable observable results so agents can build reusable GUI operations.

AUV is meant to work with coding agents and agent products such as:

That means:

  • If your agent can call a CLI, AUV can be used as computer use.
  • If your agent can write code, AUV can move repeated GUI work into reusable Rust or JavaScript/TypeScript operations. Python bindings remain planned. Once a GUI flow is finalized as an operation, repeated execution can approach zero reasoning-token cost.

Why even build AUV?

AUV born from the grounding knowledge of building general gaming agents for Project AIRI, since 2024, we tried to build agents to allow LLMs to play the following games, you can find how we implement the agents in the following repos:

There are more games we implemented where you can find in Project AIRI organization, but these four requires YOLO, OCR, screen understanding, and computer-use capabilities.

Now you have the framework to build for any applications, games.

Since Vercel published the agent-browser, we fell in love with it and have it assisted agents to build many web projects, but we found that the loop it requires for agents to call agent-browser CLI to execute the commands is too slow and inefficient, while in computer use world, many operations can be repeated thousands of times, just like how Playwright/Vitest would allow us to write E2E test for applications, why don't we expand this idea of writing code to control application to computer use world?

  • Scroll scan is a major reason AUV exists. Most desktop automation stacks can scroll or read a screenshot, but they do not turn a native app's visual list into page records, row candidates, crop artifacts, OCR fragments, and inspectable stop reasons. AUV's current scroll-scan implementation is still contract work, so the old public scan window-region CLI was removed until the reusable API is clear.
  • Feedback means the automation returns machine-readable evidence after an attempt: what input path was used, what changed, what artifacts were captured, whether verification passed, and why an operation should retry, stop, or fail.
