EditThisCookie had 3M users before Chrome removed it. A shady clone immediately scammed 50K people. CrumbKit is my answer: a cookie editor that's free, open source (MIT), and 100% local — zero network requests, zero tracking. Features: privacy score (powered by Disconnect.me tracker DB), cookie classification, JSON/Netscape/cURL import & export, undo support, dark mode, domain whitelist. Built on Manifest V3. Part of the WayKnow family of privacy-first developer tools.
