Sites like FollowThatPage, one verdict each

Follow That Page is one of the web's oldest page watchers: give it a URL and an email address, and it mails you the lines that changed. It still works. But if your inbox now holds forty diffs about rotating timestamps, you are probably searching for sites like FollowThatPage that do a little more thinking. Here are six, each with the one sentence you need.

The short version

1. AyeWatch

Verdict: the one that reads the page for you.

AyeWatch takes a URL and a sentence such as "alert me when a new episode is listed" and stays quiet until that happens. When it fires, you get a short summary instead of a diff. Alerts land in its iOS and Android apps as push on every plan, with email, Slack, Discord and webhooks on paid plans. It also watches topics across the web and accounts on X, Reddit, YouTube, LinkedIn, Instagram and TikTok, which no other tool here tries. Paid plans start at $9 a month.

2. Distill

Verdict: for people who want to point at one number and watch it.

You select an element and set a condition. Local checks run in your browser extension or desktop app and are free, but stop when the machine sleeps. The free plan has 25 monitors, only 5 of them in Distill's cloud, checked every 6 hours at best. Starter is $15 a month.

3. changedetection.io

Verdict: the hacker's choice, if you enjoy running things.

Open source, free on your own hardware, or $8.99 a month hosted with 5,000 URL watches. CSS and XPath targeting, browser steps for logins, and 85 or more notification channels. The trade is upkeep and a plain interface.

4. Visualping

Verdict: before-and-after screenshots with AI notes.

Visual, text or element comparison, with AI summaries even on the free plan, which covers 5 pages and 150 checks a month. Personal plans start at $14 a month. Pricing follows checks, so frequent checks on many pages add up.

5. Wachete

Verdict: a budget option for pages behind a sign-in.

Watches whole pages or chosen sections, handles login-protected and dynamic pages, and has a free plan that checks daily. The interface shows its age.

6. Page Monitor

Verdict: free, private, and only on while your browser is.

A Chrome extension: pick an element, pick an interval, get a browser notification. Data stays on your device. No email or chat alerts.

And Follow That Page itself?

It is a hobby project run by one developer, Onno Zweers, and it is honest about its limits. It does not run JavaScript, it will never follow password-protected pages, and free accounts get 20 daily checks plus one hourly check. For one or two plain pages where any change is worth an email, it is free and fine. Keep it for those.

For everything else, especially pages that change constantly in ways you do not care about, a tool that understands the change will save more time than one that lists it. AyeWatch's Free Preview gives you three runs to try that on a real page, no card needed, and its longer write-up on FollowThatPage alternatives has more detail on each tool.
