FOCUS ON WHAT MATTERS TO YOU
Start with your business decisions to choose the pages worth monitoring.
Build your monitoring approach ↗A price drops or a discount appears. Check the conditions before changing your positioning.
A product appears or disappears from the monitored part of a collection, or its displayed stock status changes.
A free shipping threshold or a commercial condition changes on a compatible page.
Detection depends on the data that can be extracted. Monitoring a collection does not mean its entire catalogue is covered, particularly when it spans multiple pages.
CLEAR EXPECTATIONS
An alert helps you ask the right question. The decision is yours.
Unstable or repetitive content is filtered; ambiguous changes may require confirmation. Every alert links back to its source.
Public access, page structure, JavaScript, restrictions on automated access and pagination affect extraction. Compatibility and coverage are checked during setup; complete coverage is not guaranteed.
When no significant alert has been sent, a weekly summary keeps you informed about monitoring activity.
STRAIGHTFORWARD PLANS FROM DAY ONE
Start with the pages that inform your decisions. Expand your monitoring as your needs grow.
The Starter trial lets you evaluate the service on a small real set of compatible public pages, up to 5 URLs. Request it through the form and we will confirm setup with you. Business and Pro remain available directly, without a trial.

Compatibility is not universal. Public accessibility and page structure determine what can be monitored. We check compatibility and coverage during setup. Some websites restrict automated access; we may suggest another public page instead. Pagination and extraction limits can restrict the portion of a collection we monitor: one URL does not guarantee coverage of the entire catalogue.
Public URLs: product pages, collections, pricing, promotions or delivery terms. We check compatibility during setup. Pages that require a login are not supported.
Choose your plan and subscribe directly through Stripe Checkout. We then work with you to finalise the pages to monitor, their compatibility and coverage, and the included manual setup. If you have a question before paying, you can use the contact form; it is not required to subscribe. Payment does not set up monitoring automatically.
No. Setup is carried out manually with you. You receive alerts by email, with no software or browser extension to install.
Once a day with Starter and Business, and up to three times a day with Pro. The agreed frequency is confirmed during setup. This is not real-time monitoring.
Price changes, new or removed products, promotions, delivery terms, availability and offers, depending on what is visible on the monitored pages. Detection of every change is not guaranteed.
We do not send artificial alerts. When no significant alert has been sent, a weekly summary confirms that monitoring is active and reports on its activity.
