What WaterCrawl is

WaterCrawl is a crawling framework aimed at the preparation step: scrape pages, clean the content and emit structured data that a language model can use, rather than leaving teams to build that plumbing themselves.

What you can do with it

  • Crawl sites for retrieval content
  • Clean scraped pages automatically
  • Output structured data for pipelines
  • Keep model inputs current
  • Automate recurring collection

Who it is for

  • Developers building retrieval applications
  • Data teams preparing corpora
  • AI application builders

What to watch out for

  • Crawling must respect robots directives and site terms; the framework does not change your obligations
  • Scraped pages often contain personal data, so lawful basis and retention apply
  • Content changes constantly, which becomes a correctness problem for retrieval
  • Structured output needs validation before it reaches anything users see

Pros & cons

✓ What we like

  • Handles the whole preparation step
  • Output shaped for model use
  • Free tier to test

! What to watch out for

  • Robots and terms still govern crawling
  • Personal data in scraped pages
  • Staleness affects retrieval
