web2llm 0.5.1

A tool to scrape web content into clean Markdown for LLMs.

Web2LLM

A command-line tool to scrape web pages, GitHub repos, local folders, and PDFs into clean, aggregated Markdown suitable for Large Language Models.

Description

This tool provides a unified interface to process various sources—from live websites and code repositories to local directories and PDF files—and convert them into a structured Markdown format. The clean, token-efficient output is ideal for use as context in prompts for Large Language Models, for Retrieval-Augmented Generation (RAG) pipelines, or for documentation archiving.

Installation

For standard scraping of static websites, local files, and GitHub repositories, install the base package: ___bash pip install web2llm

---

To enable JavaScript rendering for Single-Page Applications (SPAs) and other dynamic websites, you must install the [js] extra, which includes Playwright: ___bash pip install "web2llm[js]"

---

After installing the js extra, you must also download the necessary browser binaries for Playwright to function: ___bash playwright install

---

Usage

Command-Line Interface

The tool is run from the command line with the following structure:

___bash web2llm -o <OUTPUT_NAME> [OPTIONS]

---

• <SOURCE>: The URL or local path to scrape.
• -o, --output: The base name for the output folder and the .md and .json files created inside it.

All scraped content is saved to a new directory at output/<OUTPUT_NAME>/.

General Options:

• --debug: Enable debug mode for verbose, step-by-step output to stderr.

Web Scraper Options (For URLs):

• --render-js: Render JavaScript using a headless browser. Slower but necessary for SPAs. Requires installation with the [js] extra.
• --check-content-type: Force a network request to check the page's Content-Type header. Use for URLs that serve PDFs without a .pdf extension.

Filesystem Options (For GitHub & Local Folders):

When scraping a local folder or a GitHub repository, web2llm will automatically find and respect the rules in the project's .gitignore file. This ensures that the scrape accurately reflects the intended source code of the project.

• --exclude <PATTERN>: A .gitignore-style pattern for files/directories to exclude. Can be used multiple times.
• --include <PATTERN>: A pattern to re-include a file that would otherwise be ignored by default or by an --exclude rule. Can be used multiple times.
• --include-all: Disables all default, project-level, and .gitignore ignore patterns, providing a complete scrape of all text-based files. Explicit --exclude flags are still respected.

Configuration

web2llm uses a hierarchical configuration system that gives you precise control over the scraping process:

1. Default Config: The tool comes with a built-in default_config.yaml containing a robust set of ignore patterns for common development files and selectors for web scraping.
2. Project-Specific Config: You can create a .web2llm.yaml file in the root of your project to override or extend the default settings. This is the recommended way to manage project-specific rules.
3. CLI Arguments: Command-line flags provide the final layer of control, overriding any settings from the configuration files for a single run.

Examples

1. Scrape a specific directory within a GitHub repo: ___bash web2llm 'https://github.com/tiangolo/fastapi' -o fastapi-src --include 'fastapi/'

---

2. Scrape a local project, excluding test and documentation folders: ___bash web2llm '~/dev/my-project' -o my-project-code --exclude 'tests/' --exclude 'docs/'

---

3. Scrape a local project but re-include the LICENSE file, which is ignored by default: ___bash web2llm '.' -o my-project-with-license --include '!LICENSE'

---

4. Scrape everything in a project, including files normally ignored by .gitignore: ___bash web2llm . -o my-project-full --include-all --exclude '.git/'

---

5. Scrape just the "Installation" section from a webpage: ___bash web2llm 'https://fastapi.tiangolo.com/#installation' -o fastapi-install

---

6. Scrape a PDF from an arXiv URL: ___bash web2llm 'https://arxiv.org/pdf/1706.03762.pdf' -o attention-is-all-you-need
