description: Automate Electron desktop apps (VS Code, Slack, Discord, Figma, Notion, Spotify, etc.) using agent-browser via Chrome DevTools Protocol. Use when the user needs to interact with an Electron app, automate a desktop app, connect to a running app, control a native app, or test an Electron application. Triggers include "automate Slack app", "control VS Code", "interact with Discord app", "test this Electron app", "connect to desktop app", or any task requiring automation of a native Electron application.

# Electron App Automation

Automate any Electron desktop app using agent-browser. Electron apps are built on Chromium and expose a Chrome DevTools Protocol (CDP) port that agent-browser can connect to, enabling the same snapshot-interact workflow used for web pages.

## Core Workflow

1. **Launch** the Electron app with remote debugging enabled
2. **Connect** agent-browser to the CDP port
3. **Snapshot** to discover interactive elements
4. **Interact** using element refs
5. **Re-snapshot** after navigation or state changes

```bash
# Launch an Electron app with remote debugging
open -a "Slack" --args --remote-debugging-port=9222

# Connect agent-browser to the app
agent-browser connect 9222

# Standard workflow from here
agent-browser snapshot -i
agent-browser click @e5
agent-browser screenshot slack-desktop.png
```

## Launching Electron Apps with CDP

Every Electron app supports the `--remote-debugging-port` flag since it's built into Chromium.

### macOS

```bash
# Slack
open -a "Slack" --args --remote-debugging-port=9222

# VS Code
open -a "Visual Studio Code" --args --remote-debugging-port=9223

# Discord
open -a "Discord" --args --remote-debugging-port=9224

# Figma
open -a "Figma" --args --remote-debugging-port=9225

# Notion
open -a "Notion" --args --remote-debugging-port=9226

# Spotify
open -a "Spotify" --args --remote-debugging-port=9227
```

### Linux

```bash
slack --remote-debugging-port=9222
code --remote-debugging-port=9223
discord --remote-debugging-port=9224
```

### Windows

```bash
"C:\Users\%USERNAME%\AppData\Local\slack\slack.exe" --remote-debugging-port=9222
"C:\Users\%USERNAME%\AppData\Local\Programs\Microsoft VS Code\Code.exe" --remote-debugging-port=9223
```

**Important:** If the app is already running, quit it first, then relaunch with the flag. The `--remote-debugging-port` flag must be present at launch time.

## Connecting

```bash
# Connect to a specific port
agent-browser connect 9222

# Or use --cdp on each command
agent-browser --cdp 9222 snapshot -i

# Auto-discover a running Chromium-based app
agent-browser --auto-connect snapshot -i
```

After `connect`, all subsequent commands target the connected app without needing `--cdp`.

## Tab Management

Electron apps often have multiple windows or webviews. Use tab commands to list and switch between them:

```bash
# List all available targets (windows, webviews, etc.)
agent-browser tab

# Switch to a specific tab by id (t1, t2, …; integers not accepted)
agent-browser tab t2

# Switch by URL pattern
agent-browser tab --url "*settings*"
```

## Webview Support

Electron `<webview>` elements are automatically discovered and can be controlled like regular pages. Webviews appear as separate targets in the tab list with `type: "webview"`:

```bash
# Connect to running Electron app
agent-browser connect 9222

# List targets -- webviews appear alongside pages
agent-browser tab
# Example output:
#   0: [page]    Slack - Main Window     https://app.slack.com/
#   1: [webview] Embedded Content        https://example.com/widget

# Switch to a webview
agent-browser tab t1

# Interact with the webview normally
agent-browser snapshot -i
agent-browser click @e3
agent-browser screenshot webview.png
```

**Note:** Webview support works via raw CDP connection.

## Common Patterns

### Inspect and Navigate an App

```bash
open -a "Slack" --args --remote-debugging-port=9222
sleep 3  # Wait for app to start
agent-browser connect 9222
agent-browser snapshot -i
# Read the snapshot output to identify UI elements
agent-browser click @e10  # Navigate to a section
agent-browser snapshot -i  # Re-snapshot after navigation
```

### Take Screenshots of Desktop Apps

```bash
agent-browser connect 9222
agent-browser screenshot app-state.png
agent-browser screenshot --full full-app.png
agent-browser screenshot --annotate annotated-app.png
```

### Extract Data from a Desktop App

```bash
agent-browser connect 9222
agent-browser snapshot -i
agent-browser get text @e5
agent-browser snapshot --json > app-state.json
```

### Fill Forms in Desktop Apps

```bash
agent-browser connect 9222
agent-browser snapshot -i
agent-browser fill @e3 "search query"
agent-browser press Enter
agent-browser wait 1000
agent-browser snapshot -i
```

### Run Multiple Apps Simultaneously

Use named sessions to control multiple Electron apps at the same time:

```bash
# Connect to Slack
agent-browser --session slack connect 9222

# Connect to VS Code
agent-browser --session vscode connect 9223

# Interact with each independently
agent-browser --session slack snapshot -i
agent-browser --session vscode snapshot -i
```

## Color Scheme

The default color scheme when connecting via CDP may be `light`. To preserve dark mode:

```bash
agent-browser connect 9222
agent-browser --color-scheme dark snapshot -i
```

Or set it globally:

```bash
AGENT_BROWSER_COLOR_SCHEME=dark agent-browser connect 9222
```

## Troubleshooting

### "Connection refused" or "Cannot connect"

- Make sure the app was launched with `--remote-debugging-port=NNNN`
- If the app was already running, quit and relaunch with the flag
- Check that the port isn't in use by another process: `lsof -i :9222`

### App launches but connect fails

- Wait a few seconds after launch before connecting (`sleep 3`)
- Some apps take time to initialize their webview

### Elements not appearing in snapshot

- The app may use multiple webviews. Use `agent-browser tab` to list targets and switch to the right one

### Cannot type in input fields

- Try `agent-browser keyboard type "text"` to type at the current focus without a selector
- Some Electron apps use custom input components; use `agent-browser keyboard inserttext "text"` to bypass key events

## Supported Apps

Any app built on Electron works, including:

- **Communication:** Slack, Discord, Microsoft Teams, Signal, Telegram Desktop
- **Development:** VS Code, GitHub Desktop, Postman, Insomnia
- **Design:** Figma, Notion, Obsidian
- **Media:** Spotify, Tidal
- **Productivity:** Todoist, Linear, 1Password

If an app is built with Electron, it supports `--remote-debugging-port` and can be automated with agent-browser.
