Zero production cost via conditional exports swapping to no-ops in production builds.
Cuts AI agent token waste from 10k to 200 by mapping DOM pixels directly to source files.
Extension unavailable on Chrome Web Store, and WhatTheFont already does this free.
Extracts GSAP and Framer Motion animations that standard inspectors miss.
Dots nails a clear product boundary: not full-precision sharing, not nothing — just city/place-level presence with audience controls and custom 'special places'. The site uses concrete micro-stories (Vermont, Back Bay) and features like nearby notifications to sell the workflow. Biggest questions: it's iOS-only and the privacy/anti-abuse mechanics (how fuzzy the locations are, spoof resistance, opt-in audience controls) are unexplained — that's the product risk, not the copy or UI.
CDP-level spoofing with toString masking survives fingerprinting checks.
