Read any store in two clicks.

MurmSpy turns public data into a clear read on any Shopify store or TikTok Shop listing — right on the page. No account, no setup.

Open any Shopify store

A competitor, a store you found in an ad, anything running on Shopify.
Click the M icon in your toolbar

Top-right of Chrome. Pin it once and it's always a click away. The panel slides in over the store.
Read the store

Best sellers, pricing spread, launch cadence, the apps and theme it runs, an ad footprint, and a watchlist that flags what changed since last time.

A few things worth knowing

Every estimate is honestly labeled — MurmSpy never invents a number it can't show its working for.
It reads only public storefront data. No affiliate links, no session recording, no email harvesting.
Custom domain (not .myshopify.com)? Click the icon once to scan it — that's what the click grants.
Save a store to your watchlist and MurmSpy shows a "what changed" diff on your next visit.

Free to use. Pro unlocks full catalogs, complete rankings, 24-month cadence, unlimited exports and the TikTok module — but the free tier is genuinely useful on its own.
