Website Change Monitor

Watch any part of a web page and see what changed: prices, stock, versions, text. Free, private, no account.

Right-click any page, choose “Monitor this page” and click the part you care about. Website Change Monitor checks it in the background and tells you what changed, not just that something did: 🔔 MacBook Pro — Price dropped: $1,499 → $1,399 (−6.7%) 🔔 Concert tickets — Now in stock (was: Sold out) 🔔 vite releases — v4.2 → v4.3 WHAT PEOPLE USE IT FOR • Prices and restocks in any online shop • Apartment and job listings • Ticket and appointment availability • GitHub releases, changelogs and docs • Government and public information pages WHY IT'S DIFFERENT • Shows the value: old → new in every notification and in the list, with the price change in percent. • Quiet by default: watches only the element you picked, ignores ads and timestamps, and never treats an error as a change. • Simple conditions: notify only when the price drops, drops below a target, or the item is back in stock. • Never fails silently: every monitor shows when it was last checked, and a clear message with a one-click fix when something needs attention. • Works with pages that need you to be signed in, using your normal browser session. • Pages built with scripts are supported: if a plain download can't see the value, the check briefly opens the page in a background tab. • History of every change, with a small chart for prices and a highlighted diff for text. FREE, PRIVATE, NO ACCOUNT • Completely free: unlimited monitors, checks as often as every minute, no ads. • Everything stays on your device. No servers, no tracking, no analytics. • Site access is asked per site, only when you add a monitor. • Export and import all your monitors and history. GOOD TO KNOW Checks run while your browser is open. When it opens again, missed checks run right away. Available in English, Español, Português (Brasil), Français, Deutsch, Italiano, 日本語, 简体中文, 한국어 and Türkçe.
