GitHub - 0xMassi/webclaw: Fast, local-first web content extraction for  LLMs. Scrape, crawl, extract structured data — all from Rust. CLI, REST  API, and MCP server. · GitHub

Recently, while working on a RAG project, I needed to feed a large volume of technical documentation into a large language model.

At first, I used a conventional web crawling approach, but the retrieved content was disastrous—navigation bars, footers, ads, and script code all mixed together. In a 50,000-token HTML page, the truly useful content was less than 800 tokens.

Even more frustrating was that some websites had Cloudflare protection, directly returning 403 errors or captcha pages. Using Playwright to run a headless browser was slow and heavy, with each request taking several seconds.

I searched through countless projects on GitHub and tried tools like trafilatura, newspaper3k, readability, etc., but the results were all unsatisfactory.

Until I discovered webclaw, it truly opened the door to a new world!
