Competitor radar · Shopify

Nothing your rivals do
goes unnoticed.

StoreSentry watches the Shopify stores you compete with around the clock — price moves, launches, restocks, sell-outs — and signals you within the hour, by email or Telegram.

Free plan · 14-day trial on paid plans · Billed through Shopify · No access to your store's business data

Install StoreSentry on your store

StoreSentry is a Shopify app — it lives in your admin next to the others. No separate account, no credit card: billing runs through your regular Shopify invoice, with a 14-day trial on paid plans.

Or install straight from here
.myshopify.com

Enter the part before .myshopify.com. We'll hand you over to Shopify's own install screen.

01

Install in two clicks

Approve on Shopify's screen. StoreSentry asks for no access to your store's business data — only your contact details, so we know where to send the digest.

02

Add competitors

Paste the URLs of stores you compete with. We snapshot them immediately.

03

Get your digest

Price drops, launches, restocks — email or Telegram, on your schedule.

Stop checking competitor stores by hand

You already peek at their catalogues "once in a while". StoreSentry does it every hour, never forgets, and only speaks up when something actually changed.

01

Name your rivals

Add the Shopify stores you compete with — just their URL, nothing else required.

02

We keep watch

Their public catalogue, checked on a schedule, remembered in full — every meaningful change detected.

03

You get the signal

Price drop, new product, restock or sell-out — an alert lands within the hour.

Everything a competitor does, on your radar

Built for merchants with 1–15 direct competitors, not for enterprise pricing teams.

I

Price change alerts

Every increase, discount and sale the moment it goes live — with the old and the new price side by side.

II

New product alerts

Know when a competitor launches something before your customers are the ones telling you.

III

Restock & sell-out signals

A rival sells out of a bestseller? That's your window. Get told, and act while it's open.

IV

Price history

Every tracked product keeps a full price timeline, so you read patterns instead of snapshots.

V

Telegram & email

A quiet daily digest or instant pings — your choice, set per competitor.

VI

Public data only

We read what any visitor of their store can see. No logins, no bypassing, no grey areas.

Plainly priced

Billed through Shopify alongside your store subscription. No separate card, cancel whenever you like.

Questions merchants ask

Straight answers, including the ones that don't flatter us.

Is it legal to monitor competitor stores?

Yes. StoreSentry reads publicly available catalogue data — the same information any visitor sees in their browser. We don't log in, bypass protections, or collect personal data.

Which stores can I monitor?

Any store on Shopify or modern WooCommerce — between them, the vast majority of small and mid-size DTC brands. Paste a URL and the platform is detected automatically. Custom and bot-protected sites are covered as done-for-you work; see the roadmap.

Do competitors know I'm watching them?

No. Monitoring is entirely passive and indistinguishable from ordinary store traffic.

Is it safe to use on my live store?

Yes. StoreSentry asks for no access to your store's business data — no orders, no customers, no products, no analytics. The only thing it can see is your store owner contact details, which is how we know where to send your digest. Everything it monitors comes from your competitors' public catalogues.

What does installing actually involve?

Two minutes: enter your store name above, approve on Shopify's screen, paste your competitors' links. Billing, if you upgrade, goes through your regular Shopify invoice.

Can I try it before installing anything?

Yes — the free Shopify Store Checker gives you an instant snapshot of any store's catalogue, no signup. It's the one-off version of what StoreSentry does continuously.

Your competitors won't wait.
Neither should you.

Two minutes to install — free plan available, no credit card, billed through Shopify only if you upgrade.
