Magpie’s watch list: three competitors’ pricing pages checked every hour, six hours and day, Northwind’s marked changed, +6 words.

The old way vs Magpie

Checked every Monday, or checked every hour.

The old way

  • Someone checks six competitor pages every Monday, when they remember.
  • A price moved three weeks ago and the deck still quotes the old one.
  • The alert tool fires on cookie banners and font changes, so nobody reads the alerts.
  • Monitoring services bill per page per month, so you watch the cheap handful.

With Magpie

  • Magpie checks every page on the schedule you set and never forgets a Monday.
  • You hear the day it changes, with the old number beside the new one.
  • It compares the words on the page, not its code, so a restyle or a new script is never a change.
  • Flat $49 a month, so watch six pages or six hundred.

How it works

From a pricing page to a message where you work.

  1. 01Watch

    Add the pages

    Paste the pricing pages you want to keep an eye on, and pick how often each one is checked.

    A pricing page’s address and a 24h interval in the watch bar, above the pages already watched.
  2. 02Compare

    Magpie checks, and compares

    Every check is held against the last one. What moved is shown in plain language, not raw page code.

    What moved on Northwind’s pricing page: $49 out and $59 in, a new line on annual billing, and the trial cut from 14 days to 7.
  3. 03Notify

    Get told where you work

    Get a desktop notification, or send each change as a signed webhook to n8n, Zapier or a server of your own.

    The Pricing alerts webhook in Settings: three signed watch.changed deliveries, each answered 200 within milliseconds, and desktop notifications for watch changes switched on.

Questions

Price monitoring, answered.

How often does it check?

As often as you choose, page by page — every five minutes, every hour, once a day, or any number of minutes you set. Checks run on your computer while Magpie is open or in the tray, so there is no per-check fee.

What stops it alerting on every tiny edit?

Magpie compares the words on the page, not its code, so a restyle, a new script or a tracking tag is never a change. When the words do change, the diff shows exactly which ones.

Where is the history kept?

On your machine, with every other snapshot Magpie takes. You can look back at any earlier version of a page without asking anyone’s permission.

Stop renting credits.
