Shopify Spy & Product Research – App Detector + TikTok Shop | MurmTools

About

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. Estimates are labeled and explained. The blur on Pro
  features hides your real data computed on your machine — not placeholder
  noise.
• Fast and quiet. A slim bar that expands when you ask. No spam, no
  injected junk, no affiliate links.
• Private by design. Reads only public store data. Watchlist and settings
  live in local storage. No account, no server, nothing phones home.
• Updated weekly. Detectors are maintained continuously — when platforms
  change, MurmSpy heals in days, not months.
