Monitor Websites & RSS Feeds. Get Alerts From Anything. No Servers Required. Get instant alerts when a website changes, an RSS feed updates, or your own scripts and devices need your attention. No accounts, no servers, no technical setup. START MONITORING IN SECONDS Add any website or RSS feed with a tap. Send notifications from any script, server, or web app with a single webhook call. Your device does the work, so there is nothing to host and nothing to sign up for. WATCH THE WEB • Visual change detection with side-by-side comparisons, so you see exactly what changed • RSS, Atom, and JSON Feed monitoring: paste a site address and Notify! finds the feeds for you • Check intervals from 15 minutes to 7 days, per site • CSS selectors narrow a watch to one part of a page, like a price or a stock status ALERTS FROM YOUR OWN SCRIPTS • Every device gets a personal webhook URL that anything can call: a shell script, a CI pipeline, Home Assistant, Homebridge, or plain curl • Custom sender icons and full-size images • Device Groups give several devices one shared URL, so one call reaches every screen you own LIVE ACTIVITIES • Put a live tile on your Lock Screen and in the Dynamic Island, driven by the same simple URLs • Progress bars move in place and countdowns tick on their own, even while the app is closed • Made for anything with a duration: a build, a backup, a delivery, a 3D print, a wash cycle BEACONS: MONITORING IN REVERSE • Instead of telling you when something happens, a beacon tells you when something STOPS happening • Paste its ping URL into a cron job or backup script. If the ping does not arrive in time, you hear about it • The only way to find out that the thing which was supposed to alert you has itself gone quiet EVERY SCREEN YOU OWN • Home screen widgets, and a full year of searchable history SIMPLE FOR EVERYONE, DEEP FOR PROS No coding needed for websites and feeds. Developers get a documented API, Shortcuts and Siri support. YOUR PRIVACY, YOUR CHOICE Local Mode: everything runs on device. No external connections. Notifications Only: a pure push receiver for your webhooks and automations. Server Mode: connect your own ChangeDetection.io instance. MDM ready: alert your teams across managed devices. Notify! can run in local-only mode, which shares nothing but a random device ID and token not tied to any personal information. Notifications Only and Server modes process data with your consent to enable cloud functions such as automation tools, cross-device delivery, and Shortcuts support, and are likewise not tied to any personal information. WHY NOTIFY! Traditional monitoring wants a server, a subscription, and an afternoon. Notify! works in seconds, whether you are tracking a price, following a release feed, or catching alerts from your own code. Start simple and go as deep as you like.
