Niche Price Monitoring Tool

A hyper-focused price monitoring SaaS for a specific resale niche (e.g. sneakers, collectibles) that alerts buyers and sellers to price changes across platforms like StockX, GOAT, and eBay.

01 THE IDEA

Generic price monitoring tools like Prisync and Visual Ping charge $200–$1,000/month but serve everyone, which means they serve no one perfectly. The opportunity is to build a niche-specific price tracker — for example, sneaker resale prices — using Firecrawl to scrape StockX, GOAT, and eBay daily and send automated alerts when prices hit thresholds.

The product charges $50–$500/month and can be built over a weekend using Firecrawl's API plus a simple dashboard. The key insight is that niche buyers and resellers are highly motivated and will pay for precision data that a generic tool can't provide. High automation potential since scraping and alerting can run on a schedule with minimal human intervention.

03 THE VERDICT

Low build cost, high automation, and a passionate niche audience willing to pay. The sneaker resale market is large and underserved by generic tools. Weekend-buildable with Firecrawl makes the risk minimal. The key execution risk is choosing the right niche and acquiring the first 20 paying customers.
