Early access — founding cohort now forming
Your products just got disapproved.
When would you have noticed?
FeedSiren watches your Google Merchant Center account around the clock and sends one clean alert when new disapprovals or feed errors appear. Monitoring only — we never touch your feed.
Built in Germany · EU-hosted · Read-only access to your account
Merchant Center shows you errors — if you log in and look
Feeds break silently
A price change, an expired image URL, a landing-page error after a theme update — and Google starts pulling products from Shopping without asking you.
Nobody logs in daily
Disapprovals sit unnoticed in a dashboard you only open when something already feels wrong. Meanwhile your ads quietly stop showing.
You find out from revenue
The usual alarm is a dip in the sales graph — days later. That's the most expensive monitoring system in e-commerce.
How FeedSiren works
Connect
Sign in with Google and connect your Merchant Center account. Read-only — two minutes, no feed changes, no code.
We watch
FeedSiren checks your account every 6 hours (hourly on Agency) and compares against the last snapshot to find what's new.
One clean alert
New disapprovals or errors trigger a single batched message per account — email, Slack, or webhook — with the error explained in plain English.
Alerts on changes, not standing states.An issue that's been open for three weeks won't ping you every morning. Noisy monitoring gets uninstalled — so we don't do noisy.
A smoke detector, not a feed suite
Feed management platforms build, transform, and optimise your product data — big tools with big price tags. FeedSiren does exactly one job: it tells you the moment something breaks, before your revenue does. We will never edit your product data.

Frequently asked questions
Do you fix or edit my feed?+
No, and we never will. FeedSiren is monitoring and alerting only — we request read-only access and never touch your product data. Think smoke detector, not sprinkler system.
Which shop platforms are supported?+
All of them. We connect to Google Merchant Center itself, not to your shop — so it works whether your feed comes from Shopify, WooCommerce, a feed tool, or a custom pipeline.
How is this different from DataFeedWatch or Channable?+
Those are feed management suites: they build, transform, and optimise feeds, and are priced accordingly. FeedSiren does exactly one thing — it tells you when something breaks. Alarm, not workshop.
Will it spam me when a feed breaks?+
No. A feed break can produce hundreds of item errors at once; we batch everything into one message per account. And we alert on changes only — an issue that has been open for three weeks won't ping you daily.
Where does my data live?+
On servers in Germany (Hetzner), operated under GDPR. We store issue metadata from your Merchant Center account — not your customers' data.
When do I pay?+
Founding members are contacted personally before anything is charged. Billing starts only when your monitoring is live, and you can cancel anytime.
