How we make this list: we compare pricing pages, product documentation and public user reviews. Ratings come from G2, Capterra or Trustpilot, with the date we checked them.
Key takeaways
- Visualping is the easiest visual monitor: free for 5 pages and 150 checks a month, paid from 10 dollars a month billed yearly.
- Distill.io is the power user tool: a free plan with 25 monitors, a browser extension for pages behind logins, and paid checks as fast as every 2 minutes at its Flexi tier.
- Wachete is the budget cloud pick from 5.40 dollars a month and can even watch PDFs and documents.
- Fluxguard, which absorbed Versionista's customers, serves legal and compliance teams from about 83 dollars a month with site wide crawls.
- Price this category in checks, not plans. One page checked hourly consumes 720 checks a month, and that single fact decides which tier you really need.

Visualping is the tool marketers actually keep using, because its output, a before and after picture with the change glowing, needs no explanation in a forwarded email. For competitor pages, pricing watch and campaign landing pages, that readability is the product.
Its boundary is depth: it is a page watcher, not a crawler. A site wide compliance sweep or a thousand SKU watch belongs to Fluxguard or PageCrawl below. Within its page sized world, Visualping is the default recommendation.
What we like- The simplest setup in the category: paste a URL, select the area, choose the interval, and screenshots with highlighted differences do the rest, free plan covers 5 pages and 150 checks a month at hourly intervals, enough to prove the concept, paid from 10 dollars a month billed yearly (14 dollars monthly), with checks as fast as every 2 minutes at higher plans, AI change summaries and alerts by email, Slack and integrations, plus an API on every plan
Watch out for- It screenshots the visible viewport, so changes far below the fold on long pages can be missed unless you configure full page capture where offered, check allowances scale steeply if you want many pages checked every few minutes, visual comparison flags layout noise, cookie banners and rotating content need masking to keep alerts clean
Starting price$15/month
Free planYes
Distill is the craftsman's monitor. If you can name the exact element that matters, a fare, a clause, a version number, Distill watches that element with a precision visual tools cannot match, and its extension can watch pages that exist only inside your logged in session.
Choose it when the pages are difficult and the watcher is technical. For a marketing team that wants screenshots in an inbox, Visualping's simplicity beats Distill's depth every time, and both verdicts are about the reader, not the tool.
What we like- The most capable targeting: CSS and XPath selectors, conditions and macros watch exactly one price, one paragraph or one stock flag, a browser extension monitors locally, including pages behind logins that cloud crawlers cannot reach, free plan allows 25 monitors with 5 in the cloud, paid Starter at 15 dollars covers 50 monitors at 10 minute checks, Professional at 35 dollars reaches 5 minutes, Flexi from 80 dollars reaches 2 minutes, local monitoring in your own browser is unlimited on paid terms
Watch out for- Power means setup: selectors break when sites redesign, and maintaining them is a real chore at scale, the interface rewards tinkerers and intimidates everyone else, cloud check totals are capped per plan, and fast intervals on many monitors reach the cap quickly
Starting price$5.40/month
Free planYes
Wachete is the quiet value pick, and its document monitoring is a genuine differentiator: supplier price lists, regulatory PDFs and posted notices are exactly the files that change without announcement, and Wachete watches them natively.
For a small business monitoring a handful of important pages and files on a schedule, its hourly checks at entry price do the whole job. Scale and speed needs push up the tiers quickly, but few small watchers need either.
What we like- Cloud monitoring that runs while your devices are off, from 5.40 dollars a month for 50 static pages checked hourly, with no cap on number of checks in its plan structure, watches documents as well as pages: PDFs and spreadsheets, which most rivals cannot open, free plan covers 5 static pages checked daily, and native mobile apps keep alerts close, operating since 2014, a long record in a category of startups
Watch out for- Dynamic, JavaScript heavy pages are capped separately and tightly on lower plans, check intervals reach every 5 minutes only at upper tiers, the interface is functional rather than polished, fewer integrations than Visualping or Distill
Starting priceFrom $9/month
Free planYes
ChangeTower is the sensible middle: more businesslike than the free tools, cheaper and calmer than the compliance platforms, with an archive that turns casual monitoring into evidence. For watching your own pages, partners' pages and a short competitor list, it is sized correctly.
Pick it when the requirement is reliability and a record, rather than speed. A 20 minute detection lag is nothing for terms changes and pricing moves; it is everything for flash sales, which belong to Distill or Hexowatch instead.
What we like- Straightforward monitoring built for small teams: visual, text and HTML change detection with email and Slack alerts, a free plan covers 3 pages at several checks a day, paid from about 9 to 12 dollars a month for 25 pages with checks down to 20 minutes, keeps a change archive, so the history of a page, not only its latest edit, is available when a dispute or audit asks, set up in minutes with no selector skills required
Watch out for- Its fastest intervals and archive depth sit at upper tiers, fewer change types than Hexowatch, no answer for pages behind logins or heavy scripts at Distill's level, pricing pages and roundups differ on the entry figure, so confirm the current plan table before budgeting
Starting priceFrom $29/month
Free planNo
Hexowatch is the competitor intelligence instrument: it notices that a rival changed prices, rebuilt on a new platform and let a domain lapse, in one dashboard. Single purpose watchers answer one question; Hexowatch answers what changed anywhere that matters.
That breadth prices it above casual use and rewards an analyst who will act on the signals. Bought for three pages, it is a waste; bought for a market, it earns its tier.
What we like- The widest sensor set in this list: visual, content, keyword, price, HTML, technology stack, availability, WHOIS and sitemap monitoring in one account, Pro at 29 dollars a month (about 24 dollars billed yearly) carries 4,500 checks a month across all monitor types, Business reaches checks every 5 minutes with 10,000 checks, technology and WHOIS watches catch competitor rebuilds and domain moves that page monitors never see
Watch out for- No free plan, only a 7 day trial on Pro, pricing sources disagree on tier construction, with one roundup showing check packs from 14.99 dollars, so read its current pricing page closely, the breadth is wasted on a five page watch list, API and webhooks wait for the Business Plus tier at about 100 dollars a month
Starting priceFrom $83/month (reported)
Free planYes
Fluxguard is what compliance departments buy when a missed change has legal consequences: a changed disclosure, a drifting cookie banner, a regulator's page edited overnight. Its records and crawl depth exist so a firm can prove what a site said on a given date.
If your monitoring need has a lawyer anywhere near it, shortlist Fluxguard and accept the price band. If it does not, every cheaper tool on this page solves your problem.
What we like- Built for regulated watching: site wide crawls rather than single pages, with change records suited to legal and compliance review, absorbed Versionista's customer base, inheriting the tool long used by law firms to track regulatory and counterparty sites, covers concerns page watchers ignore, cookie and GDPR related tracking and synthetic transaction checks in its enterprise feature set, a free tier covers 3 websites for evaluation
Watch out for- Reported entry prices vary by source, about 83 to 110 dollars a month for roughly 25 pages, confirming this is an enterprise sale in self serve clothing, credit based pricing makes high frequency, site wide watching a budget conversation, total overkill for marketing use cases: the premium buys defensibility, not speed
Starting priceFree self hosted; hosted $8.99/month
Free planYes
changedetection.io is the developer's answer and the budget ceiling breaker: at self hosted prices, monitoring stops being a subscription negotiation entirely. Technical teams with a spare server get effectively unlimited, capable watching for the cost of electricity.
The trade is ownership. A monitoring tool that is itself down monitors nothing, so self hosting suits teams who already run infrastructure happily. Everyone else should take the hosted plan or a managed rival and keep the responsibility where it belongs, with a vendor.
What we like- Fully open source and free to run on your own machine or server, with unlimited watches when self hosted, a real browser engine handles JavaScript pages, with selectors, filters and trigger text for precise watching, an enormous notification range, more than 85 types, from email to webhooks to chat apps, the hosted plan at 8.99 dollars a month covers up to 5,000 watches for teams that want the tool without the server
Watch out for- Self hosting means you own the uptime, updates and browser maintenance of your monitoring system, no support desk: help is a community and documentation, fast intervals across thousands of watches can strain modest hardware, set up by command line and configuration, not by a friendly wizard
Starting price$8/month
Free planYes
PageCrawl closes the list as the volume value: when the watch list is a catalogue, a directory or a hundred competitor pages, its per page price undercuts the field by design. SEO teams monitoring client and rival pages at scale are its natural buyers.
Vet a newer vendor the way you would any supplier: start on the free tier, run it beside your current tool for a month on pages you know change, and let its alert record make the case.
What we like- Priced for volume: free covers 6 pages, and 8 dollars a month covers 100 pages, the cheapest per page maths in this comparison, checks as fast as every 2 minutes at its tiers, built for SEO style watching: many URLs, steady intervals, change alerts that scale, newer AI assisted features help configure monitoring rules across large page sets
Watch out for- A younger product with a shorter track record than Wachete or Distill, fewer specialised monitor types than Hexowatch: no WHOIS or tech stack depth, per check economics still apply at the fastest intervals on big sets, advanced compliance archiving is not its pitch
How we chose
We compared website change monitoring tools available in October 2026 across the three jobs buyers hire them for: simple page watching, precise element tracking and regulated site wide monitoring. Pricing and limits come from vendor pages and October 2026 comparisons that priced every tool from its own plan table; where sources conflict, Hexowatch and Fluxguard notably, the entries say so and advise confirming. We did not run monitoring jobs for this guide, and check allowances quoted are plan terms, not measured performance.
The check maths that decides the tier
One page checked every hour consumes 720 checks a month. Every five minutes consumes 8,640. Every two minutes consumes 21,600. Write those three numbers beside your watch list before reading any pricing page, because plans are priced on exactly this arithmetic while advertising page counts.
Match interval to the cost of being late. A competitor's price page earns hourly checks if you reprice against it, and daily checks if you merely like to know. A regulatory page earns frequent checks only while a matter is live. Most watch lists shrink by half under this questioning, and the right tier shrinks with them.
Alert quality is a configuration job, not a feature. Rotating banners, timestamps and cookie notices make naive monitors cry wolf until the alerts get ignored, and an ignored monitor is worse than none because it felt like coverage. Spend the first week tuning regions and masks on whichever tool you choose; it is the difference between a sensor and a noise source.
Finally, decide what the alert triggers. A change nobody owns is trivia. Route pricing changes to the person who sets prices, terms changes to whoever carries the risk, and your own pages' changes to whoever can roll them back. The tool is the cheap half of monitoring; the response path is the product.
Frequently asked questions
What is the difference between visual and text monitoring?
Visual monitoring compares screenshots and shows you what a page looks like after a change. Text and element monitoring compare the underlying content and can watch one exact price or clause. Visual is easier to read; element tracking is more precise and quieter. Most tools here offer both, with Distill strongest on elements and Visualping strongest on visual.
How many checks do I need?
Multiply pages by checks per day by 30. Ten pages checked hourly need 7,200 checks a month; the same pages daily need 300. That multiplication, done before shopping, tells you whether a free plan suffices or which paid tier is honest, and it explains why two plans with the same page count can differ tenfold in price.
Can these tools watch pages behind a login?
Some can. Distill's browser extension monitors inside your own logged in session. Cloud crawlers generally cannot pass logins, though some enterprise tools offer authenticated monitoring configurations. Never share account credentials with a monitoring service casually; prefer extension based watching for gated pages.
Is self hosted monitoring really free?
The software is, changedetection.io being the leading open source option. The costs move to you: a machine or server, updates, browser maintenance and your own time when it breaks. For a technical team already running servers the total is near zero; for anyone else the 8.99 dollar hosted plan is the honest price of the same tool.
Which tool should a law firm or compliance team use?
Fluxguard, which absorbed Versionista's customer base, is built for defensible records and site wide crawls, and ChangeTower's archive suits lighter duties. The requirement that decides it is evidential: if a change record may be shown to a regulator or a court, buy the tool designed to produce it.
