AnyWatch - Smart Page Value Monitor

Pick any price, stock or rating on a page and get notified the moment it changes. Runs locally in your browser.

Stop refreshing competitor pages by hand. If you sell on Amazon, Shopify, eBay or your own store, you already know the drill: open twenty competitor tabs, squint at the price, close them, repeat tomorrow. AnyWatch does that for you. How it works Open the page you want to watch and click the AnyWatch icon. Click "New Monitor", then click the price, stock text, rating, or any other text on the page. Keep the default ("notify when the value changes"), or add a threshold / keyword filter. Optionally paste a Feishu, Slack, Discord or Zapier webhook. Save. Chrome asks for that one site only. You get a browser notification — and the webhook, if you set one — the next time the value actually changes. Why AnyWatch instead of a generic page-change tool Fewer false alarms. Most monitoring tools screenshot-diff the whole page, so a rotating banner or a cookie popup triggers a "change" alert. AnyWatch watches one specific value you picked, not the whole page. Built to survive anti-bot walls. Checks run from your own browser, the same way you'd view the page yourself — not from a server farm that gets blocked. We never fail silently. If a page redesign breaks a monitor, you get a notification instead of quietly missing weeks of changes. No surprise charges. Free to use. No paywall. What you can do Unlimited monitors Edit webhook, condition and check frequency on an existing monitor Checks every 5 minutes, 1 hour, 12 hours, or 24 hours Notify when the value changes (default), or when it crosses a threshold / keyword Browser notifications while Chrome is running Optional webhook (Feishu, Slack, Discord, Zapier, n8n) — posted from your browser, not from our servers Please know Checks only run while this computer and Chrome are on. The first save takes a silent baseline so you are not notified for a value that was already true. AnyWatch re-requests the page URL; it does not watch DevTools edits in the current tab. Permissions, explained plainly AnyWatch never asks for access to "all websites" up front. Every time you add a monitor for a new site, Chrome asks you to approve that one domain. If you add a webhook, Chrome also asks for that webhook host. Privacy Monitors are stored on your device. We don't run servers that see your list or the pages you watch. If you set a webhook, your browser POSTs the alert to the URL you provided. Full policy: https://zestutil.com/anywatch/privacy-policy.html (product page: https://zestutil.com/anywatch/)
