The best website change monitoring tools in 2026
Tools that tell you when a page changes, with real prices, what each detects, and the limitation every one of them shares.
These tools do one thing: watch a URL and tell you when it changes. Simple, cheap, and more useful than it sounds, as long as you understand what they cannot do.
Prices read from each vendor's own pricing page on 4 October 2026, on monthly billing unless stated.
The tools
| Tool | Free tier | Paid from | Notable |
|---|---|---|---|
| ChangeTower | Yes | $12/mo | Cheap paid tiers, screenshots on every plan |
| Distill | Yes | $15/mo | Runs locally in the browser, so it reaches logged in pages |
| Visualping | Yes | $14/mo | Most popular, best visual diffs |
| Wachete | Yes | $5.40/mo | Cheapest paid tier, long running, handles deep crawls |
ChangeTower, $12 a month
Three published tiers at $12, $36 and $78 a month, or $10, $29 and $62 billed annually, plus enterprise and a free plan for 3 pages checked daily. Visual and text change detection, change history, and alerts by email, with Slack and webhooks from the Business tier. One of the cheapest real options.
Visualping, free then $14
Free for 5 pages and 150 checks a month, then from $14 a month ($10 billed annually) up to $350 a month ($250 billed annually). The most widely used, with the cleanest visual diff view and a good browser extension for selecting exactly which part of a page to watch.
Distill, free then $15
Free tier, then $15 and $35 a month, or $12 and $28 billed yearly, and Flexi from $80 a month. Its distinguishing feature, and a big part of Visualping vs Distill, is local monitoring: the extension checks the page from your browser using your own session, so it can watch pages that require a login. No cloud service can do that.
The limitation they all share
You have to know which URL to watch.
That sounds obvious and it is the whole problem. You will set up monitors on their pricing page, their homepage and maybe their features page. Then they publish fourteen new landing pages for cities they are expanding into, and you hear nothing, because you were not watching URLs that did not exist yet.
There are two fixes.
Watch their sitemap.xml instead of their pages. Every new page appears there. This is a good trick and most people never think of it. The alert is ugly, a wall of XML diff, but it catches everything.
Use a tool that watches the company rather than the page. Competitor monitors crawl the whole site and diff the page set, so new pages surface automatically. Competitors App at $14.90 per competitor a month under its October offer and our own Figo at $49 both do this, and Figo adds ads, rankings, content, social and reviews on the same weekly run, with a written summary.
Getting alerts you will actually read
The reason people abandon these tools is noise. Four habits fix it.
Select a region, not a page. Every good tool lets you draw a box around the part you care about. Use it. Watching a whole homepage means every rotating testimonial triggers an alert.
Daily is enough. Hourly checks on a competitor's pricing page generate forty alerts a month, of which one matters.
Use a separate email folder or a Slack channel. Alerts in your main inbox get archived unread within two weeks.
Write down why you are watching each page. Six months later you will not remember, and an alert with no context gets ignored.
The pages worth watching on a competitor
In rough order of signal.
- Pricing. The highest value page to watch. Price changes, new tiers, removed tiers, changed limits.
- Homepage hero. Positioning changes show up here first.
- Product or features. New capability announcements.
- Careers. Genuinely underrated. Three sales hires in Germany tells you about expansion before any marketing does.
- Sitemap. Everything else.
Choosing
- One or two pages: a free tier. Visualping or Distill.
- A handful of pages, on a budget: Wachete from $5.40 or ChangeTower at $12.
- Pages behind a login: Distill, because of the local extension.
- You want to know about pages that do not exist yet: watch the sitemap, or buy a company level monitor instead.
Questions people ask
What is the cheapest website change monitor?
Wachete at $5.40 a month, then ChangeTower at $12, both billed monthly. If you only need a handful of checks, Visualping, Distill, ChangeTower and Wachete all have free tiers.
Can I monitor a page behind a login?
Distill can, because it runs in your browser as an extension using your own session. Most cloud based monitors cannot.
How often can these check?
From every few minutes on paid tiers to daily on free ones. For competitor pages, daily is almost always enough and hourly just generates noise.
Why do I get alerts about nothing changing?
Rotating banners, timestamps, ad slots and personalisation trigger false positives. Every decent tool lets you select a specific region of the page, and using that feature is the difference between a useful alert and one you start ignoring.
