EveryCRT par Arclight Automata

EveryCRT flags CRT televisions and retro monitors while you browse marketplace sites, and lets you add finds to the EveryCRT.com community catalog in one click - earning you discovery points.

While you browse a listing on a supported marketplace (Facebook Marketplace, Craigslist, OfferUp, ShopGoodwill, GovDeals, Etsy, Marktplaats, Avito), the toolbar badge shows:

• 🟢 ✓ — already on EveryCRT
• 🔴 ＋ — not catalogued yet: a fresh spot you can add

One-click spotting: open the popup and press "Add to EveryCRT" - the listing joins the catalog with its photos, price, and location, credited to your account.

Keep the catalog fresh: viewing an already-catalogued Facebook, Etsy, or Avito listing quietly updates its price and sold state on EveryCRT - those sites block server-side crawlers, so your page view is the only way anyone sees them.

Detection is URL-based: the extension only contacts EveryCRT on actual listing pages, and sends just the page URL. Connecting your account happens on a consent page at everycrt.com that mints a revocable token - the extension never sees your password.

A free EveryCRT.com account is needed to add spots; the green/red check works without one.
