Description
DealSonar watches Facebook Marketplace and Vinted for you and pings you the moment a profitable listing appears. Set a monitor once (keyword, price range, condition, location radius) and DealSonar does the rest: AI filters out junk and wrong models, eBay sold comps show what the item actually sells for, and a profit calculator does fees and postage before you message the seller. Alerts via email, Discord, or Telegram.

Could you build this?
Partial The UI and notification pipeline are straightforward, but continuous real-time scraping of Facebook Marketplace and Vinted without accounts getting blocked requires dedicated anti-bot evasion infrastructure.
What it would actually take: Needs a backend service orchestrating residential proxy pools, browser automation (Playwright/Puppeteer with stealth plugins), and session rotation to evade Meta's and Vinted's aggressive bot-detection systems (Cloudflare, Akamai). Scraped data must be streamed to an AI inference queue to normalize listings and match against eBay Sold API comps before triggering push notifications via WebSockets or Telegram bots.
