Convert company sites into clean markdown for enrichment, scoring, and LLM pipelines.

Enrich leads from
real websites
Most enrichment scripts fail on the modern web: Cloudflare, dynamic rendering, and geo quirks. browser.city gives you a stealth-by-default 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.
