scrapling（scrapling 命令行）

scrapling

Scrapling is a powerful Python web scraping library with a comprehensive CLI for extracting data from websites directly from the terminal without writing code. The primary use case is the extract command group for quick data extraction.

Installation

Install with the shell extras using uv:

uv tool install "scrapling[shell]"

Then install fetcher dependencies (browsers, system dependencies, fingerprint manipulation):

scrapling install

Update to the latest version:

uv tool update "scrapling[shell]"

Extract Commands (Primary Usage)

The scrapling extract command group allows you to download and extract content from websites without writing any code. Output format is determined by file extension:

Note: All examples use --ai-targeted by default. This flag extracts only main body content, strips noise tags (script, style, noscript, svg), removes hidden elements, strips zero-width unicode characters, and removes HTML comments - ideal when output is destined for an AI model.

• .md - Convert HTML to Markdown
• .html - Save raw HTML
• .txt - Extract clean text content

Quick Start
