Craigslist New Listings Monitor — Delta Scraper

Monitor any Craigslist search and get only the listings that appeared since your last run. No duplicates, no noise — just what's new. Schedule it hourly or daily and never miss a deal again.

---

🎯 Who is this for?

• Deal hunters who want to be the first to respond to a new listing
• Resellers monitoring specific keywords for underpriced items (electronics, furniture, bikes)
• Job seekers tracking fresh postings in their city without refreshing the page all day
• Developers building price alert systems or Craigslist notification bots
• Researchers tracking listing volume and price trends over time

⚡ How the delta detection works

• First run — scrapes all current listings matching your search, saves their IDs to a Key-Value Store
• Next runs — scrapes again, compares against saved IDs, returns only listings it hasn't seen before
• Scheduled runs — runs automatically on your chosen interval; each run picks up where the last left off

Seen IDs older than 30 days are automatically purged to keep storage lean.
