Website Change Monitor Comparison
Ten tools that watch a webpage and tell you when it changes, with every figure read from the vendor's own pricing page in September 2026. Two of those pages only render their prices with JavaScript, so they were read in a browser rather than trusted to a summary. That pass turned up three numbers that are repeated across the web and are wrong.
Toolember does not sell a change monitor. We researched this market to decide whether to build one, found the published comparisons unreliable, and concluded the research was worth more than another entrant. Nothing on this page is trying to sell you anything, which is the only reason to believe the table.
Three numbers everyone repeats, and the truth
These are not small discrepancies. Each one would change which tool a reader picks.
- ChangeTower's entry plan is daily-only. It is widely listed as $15 a month for 50 monitors at ten-minute checks. Per ChangeTower's pricing page, the $12 Lite plan covers 25 pages and still checks once a day. Hourly checks start on the $36 Essential plan.
- Hexowatch has no free plan, and starts at $24.17. It is commonly described as free for 75 checks a month with paid plans from $14.99. Its pricing page shows no free tier at all and its cheapest plan at $24.17 a month for 4,500 checks.
- Wachete is far stronger than any summary says. It is usually written off as five static pages checked daily. Its own site lists that free plan as also including one JavaScript-rendered page, no cap on the number of checks, twelve months of history, monitoring of pages behind a login, and text extraction from PDF, doc, docx and xlsx files.
The ten, ordered by what you get for nothing
| Tool | Free plan | Cheapest paid plan | Renders JS |
|---|---|---|---|
| Wachete | 5 static pages + 1 dynamic, every 24h, no check limit, 12 months history, pages behind a login, text in PDF/doc/xlsx | $5.40 : 50 static + 1 dynamic, every 60 min, no check limit, 12 months history | 1 page only |
| changedetection.io | Self-hosted, unlimited, Apache-2.0, 34.4k GitHub stars, one docker run command | $8.99 : 5,000 URL watches, re-checks from about 5 min, 85+ notification types, EU/US/Tor proxies | Yes, real Chrome |
| Visualping | 5 pages, 150 checks/month, 60 min selectable, 3 months history, AI change summaries | $14 : 10 pages, 1,000 checks/month, every 15 min | Yes |
| Distill | 5 cloud + 20 local monitors, every 6h, 1,000 cloud checks/month, 30 email alerts/month, no history | $15 : 50 monitors, every 10 min, 30,000 checks/month, 2,000 alerts | Yes |
| PageCrawl | 6 pages, 220 checks/month, 60 min, 90 days history, email only | $13.33 billed annually : 100 to 300 pages, 15,000 to 45,000 checks/month, every 15 min, 12 months history | Not stated |
| ChangeTower | 3 pages, daily, 30 days history, keyword tracking | $12 ($10 annual) : 25 pages, still daily only, 30 days history | Yes |
| Hexowatch | None on the pricing page | $24.17 ($290/year) : 4,500 checks/month, every 15 min | Yes |
| Sken.io | None. 14-day trial with 140 checks | 3 euros : 500 checks/month, intervals to 1 min | Not stated |
| Follow That Page | Free email alerts. No pricing page exists on the site | Not published | No |
| PageProbe | Browser extension, unlimited local trackers | Not applicable | Runs in your browser |
The trap in every free plan: the interval you cannot afford
Most of these tools advertise a check interval and, separately, a monthly budget of checks. On the free plans the two rarely agree, and the budget always wins. Multiply pages by checks per day by thirty and compare:
| Free plan | Advertised | Budget | What it actually buys |
|---|---|---|---|
| Visualping, 5 pages | every 60 min | 150 checks | about one page every five hours, not five pages hourly |
| PageCrawl, 6 pages | every 60 min | 220 checks | about one page every four hours |
| Distill, 5 cloud monitors | every 6 hours | 1,000 checks but only 30 email alerts | the checks are affordable, the answers are not |
| Wachete, 5 static pages | every 24 hours | no limit | exactly what it says, which is why it leads the table |
Distill's version of this is the one to watch for. A thousand checks a month sounds generous next to everyone else, and then thirty email alerts a month caps what you can be told. For watching a job board or a restock, being told is the entire product.
Which one to pick
- Watching a handful of pages, free: Wachete. Daily checks are slower than Distill's six hours, but nothing is capped and you keep a year of history.
- You need it faster than daily, free: Distill, and accept thirty alerts a month. Or Visualping if you want its AI change summaries more than you want frequency.
- You can run Docker: changedetection.io, self-hosted. Unlimited, Apache-2.0, real Chrome for JavaScript pages, and visual diffing. The cost is that you are now the operator.
- Dozens of pages on a small budget: Wachete at $5.40, or PageCrawl at $13.33 annually if you want fifteen-minute checks and Slack.
- You need near-real-time: Sken.io offers one-minute intervals from 3 euros, but at 500 checks a month that is one page for about eight hours. Real minute-level monitoring means Distill Professional or PageCrawl Enterprise.
- Pages behind a login: Wachete is the only one of the ten that lists this on a free plan.
What we could not verify
Saying so is the point of a comparison like this, because the parts nobody checks are where the errors above came from. Follow That Page publishes no pricing page; its site offers a form and an email field, and reads like a long-running service run by one person. PageProbe is a browser extension rather than a hosted service, so its unlimited trackers only run while your browser does, which makes it incomparable on price by design. PageCrawl and Sken.io do not state whether they render JavaScript, and both are marked accordingly rather than guessed. Wachete publishes tiers above Starter that were not read for this page.
Method
Every figure was read from the vendor's own pricing page in September 2026, not from a review or a roundup. Hexowatch and Wachete render their prices with JavaScript, so those two pages were opened in a real browser; both turned out to differ from what the summaries say, which is probably not a coincidence. Product names and trademarks belong to their respective owners, and none of these companies was contacted or consulted. Where a vendor does not state something, this page says so instead of filling the gap.
