Many people start watching web pages with a browser extension. It is free, it installs in one click, and it sits right next to the address bar. Distill is built around one, and Visualping has a Chrome extension too. The catch shows up later with monitors that check pages from your browser: they only work while that browser is running. So if you want a Visualping extension alternative, the first question is whether your alerts should depend on your laptop at all.
How extension-based monitoring works
A monitoring extension opens the page on a timer, takes a copy and compares it with the previous one. Distill states the limit plainly: its local monitors need the browser open, and its free cloud checks run every six hours. Shut the lid on Friday evening and nothing is checked until Monday.
Extensions also ask for broad permission to read the sites you visit, and every one adds a little weight to each browsing session. That is a fair trade for a hobby, less so for an alert you rely on, like a game's price drop or the date a new season goes live.
What changes when monitoring runs in the cloud
Cloud monitors run on someone else's server, so the schedule holds whether your computer is on, asleep or in a bag. AyeWatch works this way and adds nothing to your browser. You set monitors up on the web, and alerts reach you as push notifications on iOS or Android, by email, or in Slack and Discord.
It also changes what triggers an alert. AyeWatch does not compare screenshots. It reads the page and checks it against a sentence you write, for example "tell me when this game's price drops or a release date is announced; ignore ads and banners". When something matches, you get a short note saying what changed.
Extension or cloud: the quick comparison
| Browser extension | AyeWatch | |
|---|---|---|
| Checks while your computer is off | Not for local monitors | Yes |
| What you install | An extension in each browser | Nothing (web, plus optional phone apps) |
| What sets off an alert | Any difference in the area you picked | A change that matches your rule |
| What the alert looks like | A highlighted diff | A written summary |
| Free start | Distill: 25 monitors | Three free runs, no card |
Paying for plans, not for checks
Visualping's paid tiers start at $14 a month, or $10 a month on yearly billing, and the bill grows with how many checks you use. AyeWatch prices by plan instead. Pro costs $9 a month and covers 50 monitors checked every hour. Pro+ costs $19, allows 200 monitors and adds ASAP checks for things you need to hear about within minutes.
When an extension is enough
If you only watch one or two pages, only care while you are at your desk, and like picking exact page elements, a free extension does the job fine. Visualping also stays the better choice when you want a visual before-and-after of a page rather than a written summary.
Switching takes a few minutes
Create a free account at ayewatch.ai, paste in the page your extension was watching, and describe in one sentence what should count as a change. Then remove the extension and let the checks run without your browser.
