NETTUNO

Community-powered scam protection for online marketplaces. Trust shields on every listing — free, no account needed.

NETTUNO is a community-powered trust layer for online marketplaces. WHAT IT DOES When you browse listings on supported marketplaces, NETTUNO shows a small trust shield next to each price. The shield is green if the listing has been voted as legitimate by other users, yellow for caution, and red if the community has flagged it as a likely scam. You can also contribute by voting on listings you visit — one click for trustworthy, one click to flag suspicious behavior (e.g. payment outside the platform, fake courier links, ghost profile, unrealistic price). PRIVACY FIRST - No tracking outside the supported sites. - No reading of page content — we only generate a unique ID per listing URL. - Google login is optional. Without it, you can read shields but not vote. - You can delete your account and all data at any time inside the popup. - Full Privacy Policy: https://nettuno-e6036.web.app/privacy.html WHO IT IS FOR Anyone who buys or sells second-hand online and wants a quick, unobtrusive way to spot suspicious sellers before contacting them. FREE NETTUNO is free, with no ads inside listings. The project is independent.
