Cross-platform accessibility library for reading and interacting with accessibility trees. One API for macOS, Windows, and Linux.

**Use cases:** UI testing, AI agent tooling, assistive technology, desktop automation.

**[Documentation](https://xa11y.dev)** | **[Rust API](https://docs.rs/xa11y)** | **[Python API](https://xa11y.dev/api/python/)**

## Quick Example

```python
import xa11y

# Find elements with CSS-like selectors via locator
app = xa11y.locator('application[name="Safari"]')
for button in app.descendant("button").elements():
    print(button.name)

# Interact with elements via locator (re-resolves every call)
app.descendant("button[name='Submit']").press()

app.descendant("text_field[name^='Search']").set_value("hello world")
```

## Installation

```bash
pip install xa11y
```

Requires Python 3.9+. Pre-built wheels available for Linux, macOS, and Windows.

> **macOS:** Grant your terminal **two** permissions in **System Settings > Privacy & Security**:
> 1. **Accessibility** — required for all accessibility API access.
> 2. **Screen & System Audio Recording** (macOS 26+) — required to read window content. Without this, only menu bars are visible.
>
> Restart your terminal after changing permissions.
>
> **Linux:** AT-SPI2 must be running (default on GNOME/most DEs). No special permissions needed.
>
> **Windows:** No special permissions needed.

## Selector Syntax

| `textfield[name*='email']` | Text field whose name contains "email" |
| `group > button` | Buttons that are direct children of a group |
| `window button` | Buttons anywhere inside a window |
| `button:nth(2)` | The 2nd button match |
