MurmSpy — Shopify Store Spy Chrome extension security report

The honest alternative to Koala Inspector and PPSPY — professional store analytics with competitor monitoring built in, and every estimate clearly labeled. Track any Shopify store or TikTok Shop listing. Professional store analytics for the storefront you're looking at. Open any Shopify store and a clean, light panel reads the public data your browser already loaded: what's selling, how it's priced, which apps run the stack, and what changed since your last visit. Open a TikTok Shop listing and the public sold counter becomes an honest revenue estimate at a glance. Every number is transparent about where it comes from. Facts are read straight from the page. Estimates are marked with ~ and a small ⓘ explains the method in one sentence. Nothing is fabricated. ON ANY SHOPIFY STORE ✓ Best sellers, ranked by Shopify's own best-selling sort — the canonical "what's actually selling" signal, with a clearly labeled demand index ✓ Watchlist — save a store and every visit shows what changed: new products, price moves (old → new), apps added or removed, theme swaps. Stored locally. No account required. ✓ Pricing analytics — % of catalog on discount, average and median markdown depth, a price distribution chart with the median marked, and the biggest markdowns ✓ Catalog map — every product plotted as a dot placed by its price, with discounted items ringed: the store's whole price architecture at a glance ✓ Launch cadence — products added per month, 24 months back, on a proper chart: crosshair, exact values and share-of-total on hover, arrow keys included ✓ Traffic signal — Google's Chrome UX Report says whether the store clears the real Chrome-traffic threshold (a strong small-store tell on its own), plus a one-click full traffic report ✓ Ad footprint — the store's Facebook/Instagram/TikTok identities parsed from the page, with pre-filtered links into the Meta and TikTok ad libraries ✓ App detector — 70+ maintained fingerprints (Klaviyo, Judge.me, Loox, Recharge, Rebuy, Gorgias…), each with the evidence found ✓ Theme + pixel detection (Meta, TikTok, Google, Pinterest, Snap) ✓ Store DNA export — a designed report card (1200×1500 PNG) rendered entirely in your browser: stats, top sellers, app stack, launch trend. Built to be shared in a team channel or a deck. ✓ Two CSV flavors — analysis (prices, discounts, dates) and a Shopify product-import file that loads straight into Products → Import ✓ Compare 2–3 saved stores side by side; sourcing links (AliExpress / Google Lens) on every product row — no affiliate codes, ever ✓ Confidence you can trust — when a store blocks its catalog or the data runs thin, the panel says so instead of inventing a number, and a "checked … ago · refresh" control keeps every read datestamped ✓ ⌘K command palette and "/" filter — built for speed ON TIKTOK SHOP ✓ Public sold counts, surfaced instantly ✓ Revenue estimate = sold × price, always marked ~ with the method ✓ Saturation read — early / rising / peak / saturated, from sold velocity vs listing age: is the wave still catchable? ✓ Seller credibility grade A–E from public signals ✓ Shop roll-up: totals and top products across a seller's catalog + CSV WHY MURMSPY • Honest numbers.
