I needed a crawler that feeds a RAG workflow without drowning me in noise. The adaptive crawling with stopping criteria finally returns pages that matter. Markdown output slots right into my data lake, and parallel crawling keeps pace with my sprints. The setup for stopping criteria and selectors is a touch fiddly, but worth it.

Fast multi-domain crawling with solid domain mapping, but parsing quirks linger

Used for 3-6 months

What I liked

  • The parallel crawling accelerates data collection
  • Domain mapping & SSL handling keeps multi-domain crawls organized and secure
  • Markdown output fits directly into our ML data lake
  • Open-source flexibility makes customization feasible

What could be better

  • Initial setup for cross-domain mappings and selectors is fiddly
  • Dynamic content can produce noisy fields that need post-processing
  • More practical quick-start examples would help new users

As we build a data enrichment service, speed matters. The parallel crawling and domain mapping let me harvest data across several sites quickly, while SSL handling keeps everything secure. The Markdown output integrates cleanly with our pipelines, and the open-source nature makes customization straightforward. A few quirks with dynamic pages and the learning curve for selectors slowed me briefly.
