URL → Markdown
Convert company sites into clean markdown for enrichment, scoring, and LLM pipelines.
Use Case Enrich leads from
Enrich leads from
real websites
Most enrichment scripts fail on the modern web due to Cloudflare, dynamic rendering, and geo blocks. BrowserCity gives you a bulletproof extraction primitive so your pipeline has fewer holes.
Stealth For Real Websites
Avoid bot walls that break “simple” enrichment scripts. Stealth defaults mean fewer missing fields.
Batch When It’s a Dataset
Move from a list of leads to a pipeline: batch endpoints + concurrency with predictable outputs.
Interactive Fallbacks
When a site needs clicks or login, switch to Sessions (Playwright connect) or Humanized REST tools.
Privacy Posture
Enrichment is sensitive. A zero-logs stance helps you keep customer and prospect data out of vendor systems.
Simple Primitives
Keep your enrichment logic in your stack. browser.city provides the browsing/extraction primitive, nothing else.
Extract emails (and other signals)
Fetch a lead’s website as markdown, then extract signals like emails, social links, pricing, and product keywords.
