**WebCap** is an extremely lightweight web screenshot tool. It doesn't require Selenium, Playwright, Puppeteer, or any other browser automation framework; all it needs is a working Chrome installation. Used by [BBOT](https://github.com/blacklanternsecurity/bbot).

### Installation

```bash
pipx install webcap
```

### Web Interface (`webcap server`)

### Features

WebCap's most unique feature is its ability to capture not only the **fully-rendered DOM**, but also every snippet of **parsed Javascript** (regardless of inline or external), and the **full content** of every HTTP request + response (including Javascript API calls etc.). For convenience, it can output directly to JSON.

### Example Commands

#### Scanning

```bash
# Capture screenshots of all URLs in urls.txt
webcap scan urls.txt -o ./my_screenshots

# Output to JSON, and include the fully-rendered DOM
webcap scan urls.txt --json --dom | jq

# Capture requests and responses
webcap scan urls.txt --json --requests --responses | jq

# Capture javascript
webcap scan urls.txt --json --javascript | jq

# Extract text from screenshots
webcap scan urls.txt --json --ocr | jq
```

#### Server

```bash
# Start the server
webcap server

# Browse to http://localhost:8000
```
