SigPath check

Is it a real deal? See how a price compares with the market, spot warning signs, and find a cheaper checked offer.

SigPath shows how good the deal you're looking at really is, before you buy. When you open a product page, a small SigPath panel shows: • the deal score: how far the price is from the market for the same product ("−22 %, good deal"), and the usual price range • warnings: a price too good to be true, or a seller with upheld fake-product reports • a cheaper offer for the same product that SigPath has checked • who actually sells it, where the shop says so Prefer it quiet? Turn off "Open the panel by itself": the score shows on the toolbar icon only, and a warning still opens the panel. It works by itself on the product pages of Amazon and several large German online shops (the full list is at https://sigpath.vercel.app/extension), and on any other shop when you click the icon and "Check this page". Optional, off until you turn it on: share the Amazon.de prices you see, so SigPath's search can show them to other shoppers. Only the product and its price, never anything about you. No account, no tracking. SigPath is open source: https://github.com/yc82628/sigpath SigPath is independent and not affiliated with any of the shops it works on.
