ÁrFigyelő

Hungarian webshops compete on price on Árukereső, the country's main price comparison site. Most of them check competitors by hand, a few products at a time. The established monitoring tool is priced for larger shops and expects you to paste in a link for every product you want to watch, and Árukereső's own search can't look a product up by barcode.

Distributors have the mirror-image problem: they want to see how resellers price their brands, and today that means someone clicking through listings.

ÁrFigyelő is a self-serve web app. You upload your product list as a spreadsheet; it finds each product on Árukereső by barcode or item number, collects every competitor's offer, and refreshes the whole catalogue every day.

• A dashboard that shows, per product, whether you're the cheapest, mid-field or the most expensive, with your margin and the cheapest rival.
• Price history per competitor, and a cautious price suggestion that respects your margin floor. It only advises; it never reprices anything.
• Alerts when someone undercuts you, when your margin drops below your threshold, or when the cheapest competitor runs out of stock.
• For distributors, monitoring of recommended retail prices across resellers.
• A daily to-do list, Excel exports, and a 14-day trial on four plans from 11,990 to 109,990 Ft a month.

Next.js and Supabase, with row-level security so each company can only ever read its own rows. Scheduled jobs run on Inngest. Prices come from my own collector, a real Chrome browser on a rented server, because Árukereső's bot protection blocks headless browsers. A paid scraping service is the fallback.

AI coding agents wrote the code. The decisions that mattered were mine:

• Matching products on a confidence ladder: barcode first, then manufacturer part number plus brand, then fuzzy title matching. Anything uncertain goes to a review screen where a person confirms it, because one wrong match spoils every comparison after it.
• Monitoring recommended prices, never enforcing them. Pressuring resellers to hold a minimum price is resale price maintenance, which Hungarian competition law forbids, so the product and its copy only ever report.
• Pricing 40–55% below the established tool, and refreshing every product every day on every plan once running my own collector made that cheap enough.
