WebChange is a visual change detector for the open web. You choose the exact DOM region that matters; we compare future snapshots and notify you when something shifts.
Whether you are waiting for a price drop, a “In stock” label, a competitor’s banner, or a policy paragraph to update, manual refresh is a waste of time. WebChange lets you mark an element once and receive structured alerts when that slice of the page changes.
Each monitor stores a selector and baseline snapshot of the content inside your marked region. On every check cycle, WebChange reads the current text/HTML fragment and diffs it against the last known value. When a meaningful change is detected, you get a notification with the page title, monitor name, and before/after context where available.
The free plan is designed for privacy-conscious users and quick personal watches. Checks run while you use Chrome — no AddonsStore account required, no cloud upload of your monitor list. You get up to five active monitors and native desktop notifications when a change occurs on an open or background tab (within browser limits).
Upgrade when you need reliability: our cloud workers revisit your URLs on a schedule, even if your laptop is asleep. Unlimited monitors, WebPush to your desktop, Telegram bot messages, and Discord webhook posts keep teams and power users in sync. Your monitor configuration is stored securely in the cloud so reinstalling the extension does not lose your setup.
Start free with local monitors. Move to Pro when you need always-on cloud checks and multi-channel alerts.

Visual targeting, sensible defaults on Free, and production-grade delivery on Pro.
Draw around the price, badge, or paragraph you care about. WebChange binds to that node — not the entire page body.
Scheduled fetches from AddonsStore infrastructure keep watching while your browser is closed or your PC is offline.
Free includes Chrome desktop notifications; Pro adds reliable WebPush delivery for critical price and stock events.
Pipe changes to your phone or team chat — perfect when you live in Telegram more than email.
Post structured embeds to a channel when a monitor fires — great for deal groups and ops rooms.
Track entire watchlists — SKUs, listings, forums — without hitting the five-monitor Free cap.
Pro users connect their preferred channels once, then assign per-monitor routing rules. Send high-priority stock alerts to WebPush and Telegram, while routing noisy pages only to Discord for archival.
Free users still benefit from Chrome desktop notifications while browsing — no account, no webhook setup.
On Pro, monitors live in AddonsStore cloud storage — URLs, selectors, labels, and notification preferences. Sign in on a new machine, reinstall after an update, or share templates across teammates without rebuilding from scratch.
Free keeps everything on-device: ideal when you want zero cloud footprint and only a handful of personal watches.
