MarketWatch

Value Proposition

A lightweight, self-hosted tool that monitors Facebook Marketplace for new listings matching user-defined criteria (keyword, price, location) and pushes instant Telegram alerts — no more endlessly refreshing the page or missing deals.

Target Customer

Individuals who actively buy/sell on Facebook Marketplace and want to catch new listings as soon as they appear — deal-hunters, resellers, collectors, and bargain shoppers.

Revenue Model

Open-source / free. Future options: hosted SaaS tier for non-technical users or premium features (multiple Telegram recipients, SMS alerts, advanced filtering).

KPIs

• Number of active watches per user
• Average time between listing appearing and alert sent
• Notification deliverability rate
• False-positive / duplicate rate

What's Built — v0.1.0
