Hexowatch vs ChangeTower for Page Change Detection

Hexowatch and ChangeTower both monitor web pages for changes, but their published feature sets point to different use cases. Hexowatch lists a broad range of monitoring types, including visual, content, keyword, technology, source code, availability, price, WHOIS, sitemap, API, backlink, and RSS monitoring. ChangeTower emphasizes content and AI criteria-based monitoring, selective monitoring, scheduled checks, authenticated pages, dated snapshots, and team workflows. These are vendor-described capabilities, not the result of a head-to-head accuracy test.

Choose by the change you need to detect, the shortest acceptable check interval, how much history you need, and where alerts must go. If your workflow also needs screenshot evidence or programmatic page captures, ScreenshotNeo is a separate screenshot API and MCP server to consider alongside a change monitor.

1. Quick comparison

Decision point	Hexowatch	ChangeTower
Published monitoring range	Visual, content, keyword, technology, source code/HTML, availability, price, WHOIS, sitemap, API, backlink, and RSS.	Content, AI criteria, keywords, selective monitoring, schedules, domain monitoring, and password-protected pages.
Visual change monitoring	Explicitly listed as a monitoring type.	Features page describes content, images, and DOM monitoring; confirm the specific visual comparison workflow you require.
Selective monitoring	Review the available modes and configuration for the specific page.	Listed as section monitoring on Essential and sections/elements on Business and Enterprise.
Check frequency	Pricing page lists maximum frequencies of 15 minutes for Pro and 5 minutes for Business.	Free and Lite daily, Essential hourly, Business every 20 minutes according to the current pricing page and FAQ. Verify before buying.
Published history	Homepage describes archiving; reviewed pricing material does not establish directly comparable retention durations.	30 days on Free and Lite, 60 days on Essential, six months on Business, according to the pricing page.
Alerts and team workflow	Check current plan details for integrations; reviewed pricing text does not provide a complete integrations matrix.	Email on all listed tiers; pricing lists Slack, webhooks, and MCP on Business and Enterprise. Verify Teams availability because official pages have differed.
Best initial fit	Investigate when you need one of its many specialized monitoring types, especially visual, technical, availability, or price monitoring.	Investigate for a small monitored set, criteria-based alerts, selective monitoring, dated snapshots, and shared workflows.

Feature and plan details can change. The comparison reflects vendor pages reviewed for this article and does not establish which service detects changes more accurately.

2. When Hexowatch may fit better

Hexowatch’s published feature list spans more monitoring categories than ordinary text changes. Its homepage lists visual, content, keyword, technology, source-code, availability, price, and WHOIS monitoring, as well as sitemap, API, backlink, and RSS monitoring. That breadth is useful to investigate when you need to watch multiple kinds of signals across competitor, partner, commerce, recruiting, or other pages.

Hexowatch’s pricing page lists Pro at $24.17 per month equivalent with 4,500 checks per month and a maximum 15-minute frequency; Business at $45.83 per month equivalent with 10,000 checks and a 5-minute maximum; and Business+ at $99 monthly equivalent with 25,000 checks. The displayed annual totals are $290, $550, and $999. The page also describes Enterprise as tailored and residential GEO proxy credits as an add-on starting at $9.99 monthly. Some pricing content is dynamically rendered, so verify billing terms, check definitions, and feature access on the live page before selecting a plan. See Hexowatch’s homepage and pricing page.

Hexowatch says its service is no-code and does not require software, proxies, or programming to get started. Treat this and its other performance or service descriptions as vendor statements, not independent test results.

3. When ChangeTower may fit better

ChangeTower’s public feature set centers on content and AI monitoring, keywords, selective monitoring, schedules, user actions, and workflows for teams. It describes using plain-language criteria to decide what matters, monitoring only selected sections, replaying actions such as dismissing a banner or signing in, and storing dated snapshots. These features may suit teams that want to monitor a short list of pages and route changes through a shared review process.

Its current pricing page lists Free for 3 pages checked daily; Lite for 25 pages checked daily at $12/month; Essential for 100 pages checked hourly at $36/month; and Business for 200 pages checked every 20 minutes at $78/month. Listed snapshot history is 30 days for Free and Lite, 60 days for Essential, and six months for Business. Annual billing is described as saving 20%, with equivalent monthly prices of $10, $29, and $62 for Lite, Essential, and Business. Enterprise is custom priced. The site says all prices are in US dollars. Check the ChangeTower pricing page for current terms.

ChangeTower’s FAQ and current pricing page state that Business checks every 20 minutes. Older or other official material may differ, so confirm the actual interval available to your account before relying on it. ChangeTower’s feature page lists Microsoft Teams, while its FAQ has described a native Teams integration as in development; verify the current integration status directly.

4. Compare them against your monitoring requirement

What exactly must trigger an alert?

Write down the signal in concrete terms: any visual difference, a specific phrase appearing, a product price crossing a threshold, a selected legal clause changing, a technology stack changing, or a page becoming unavailable. Then check that the vendor supports that exact signal and whether it can ignore unrelated changes. Do not assume that a broad “AI monitoring” or “visual monitoring” label behaves identically across products.

How quickly must you know?

Translate your response requirement into a maximum check interval. A 24-hour cadence is very different from a 5-minute cadence for inventory or incident response. Compare the frequency available on the exact plan, not just the vendor’s shortest advertised interval; then account for checks consumed by the number of pages and any limits on your plan.

How much history must you retain?

For audit, compliance, or incident review, check what is stored on each check, whether unchanged pages also get snapshots, how long those snapshots remain available, and whether they can be exported. ChangeTower publishes plan-specific history durations and describes dated snapshots. The Hexowatch pages reviewed describe archiving but do not state a directly comparable retention period.

Where do alerts need to go?

List required destinations and owners: email, Slack, Teams, webhooks, or an AI assistant workflow. Check which plan includes each integration, whether alerts can be routed by folder or team, and whether webhook delivery has retry behavior. ChangeTower’s official pages contain inconsistent Teams information; Hexowatch’s reviewed pricing text does not establish a complete integrations matrix.

Can the target page be monitored?

Login support does not guarantee that every target is monitorable. ChangeTower says manual actions can replay login, cookie-banner, or location-selection steps, but also says automated traffic may be blocked. Its FAQ names X, LinkedIn, Facebook, and Instagram among sites that block crawlers. Test representative pages and authentication flows before migrating a large list.

5. A practical selection process

1. Choose representative URLs. Include the normal page, a dynamic page, a page behind login if relevant, and a page with cookie banners or frequently changing content.
2. Define the change condition. For each URL, write what should alert and what should not. For example, “alert if the listed price changes” is more actionable than “alert on any page change.”
3. Set a detection deadline. Specify the maximum delay you can accept, then compare plan cadence and quotas.
4. Check the evidence requirements. Confirm snapshot contents, retention, timestamps, exports, and access permissions.
5. Check alert operations. Confirm the required destination, routing, team access, and any webhook or AI integration on the plan under consideration.
6. Trial the edge cases. Check how each service handles consent overlays, lazy-loaded content, login expiration, blocked requests, and noisy regions of a page.
7. Recalculate total cost. Include page count, check frequency, history needs, annual versus monthly billing, and any proxy or enterprise add-ons.

6. Price and capacity: compare the units carefully

The products present capacity differently. ChangeTower’s listed plans emphasize the number of pages monitored and the interval by tier. Hexowatch’s pricing page emphasizes monthly checks alongside maximum frequency. These units are not directly interchangeable: one URL checked frequently can use far more checks than one checked daily, and the vendors may count usage differently.

Before you choose, estimate the workload as monitored URLs × checks per URL during the billing period, then verify the vendor’s own counting rules and any retries or special monitoring modes. A low per-month price is not useful if its plan cannot meet your frequency, history, or integration requirements.

7. Screenshot evidence alongside change alerts

A change monitor answers whether a page changed and may retain evidence according to its plan. A screenshot API answers a different operational need: capture a page on demand and return an image or PDF for a report, workflow, or application. ScreenshotNeo is a separate tool to consider if you need screenshot evidence after a monitoring alert; it is not a replacement for Hexowatch or ChangeTower’s scheduled change detection.

ScreenshotNeo’s API accepts a URL and returns PNG, JPEG, WebP, or PDF output. Its stated features include full-page capture with lazy images loaded, CSS-selector element capture, viewport and device options, custom CSS or JavaScript, waits, request blocking, headers and cookies, caching, asynchronous jobs, bulk capture, and signed links. See the ScreenshotNeo API documentation for request options.

curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://example.com -o shot.webp

import requests

r = requests.get(
    "https://api.screenshotneo.com/v1/shot",
    params={"access_key": "YOUR_API_KEY", "url": "https://example.com"},
    timeout=90,
)
r.raise_for_status()
with open("shot.webp", "wb") as image:
    image.write(r.content)

const q = new URLSearchParams({
  access_key: 'YOUR_API_KEY',
  url: 'https://example.com'
});
const res = await fetch(`https://api.screenshotneo.com/v1/shot?${q}`);
if (!res.ok) throw new Error(`Screenshot request failed: ${res.status}`);
const image = Buffer.from(await res.arrayBuffer());
await import('node:fs/promises').then(fs => fs.writeFile('shot.webp', image));

Keep API keys on a server or in a secret manager; do not expose them in browser code. For recurring captures, set explicit timeouts and handle non-success responses before treating a response body as an image.

8. Or skip the browser setup

Use ScreenshotNeo when you need a screenshot or PDF without maintaining your own browser capture setup. Cookie banners, popups, and chat widgets are removed before the shot; bot checks, blank pages, and failed loads are never billed; an MCP server lets AI agents take screenshots; and 1,000 screenshots per month are free with no card, with paid plans starting at $5 for 3,000. Every feature is on every plan. Yearly billing gives two months free.

curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://example.com -o shot.webp

Create a free ScreenshotNeo account for 1,000 screenshots a month, with no card required.

9. Troubleshooting page monitoring

Symptom	Likely cause	What to check
No alert after a visible change	The monitor checks too slowly, the changed area is excluded, or the page has not yet been checked.	Confirm the schedule, monitored region, and last successful check timestamp.
Too many alerts	Rotating banners, timestamps, counters, ads, or personalization are being treated as meaningful changes.	Use selective monitoring, ignored regions, keywords, or criteria where available; verify the rule against several normal page updates.
Page appears unchanged to the monitor	Content may render after initial load, require interaction, or depend on a location or session.	Check JavaScript rendering, lazy-load support, recorded actions, cookies, and the page state seen by the monitoring service.
Login-protected page stops updating	The session expired or the site changed its authentication flow.	Re-record the login steps and confirm that the account can still access the target. Some sites block automated requests outright.
Alerts arrive too late	The selected plan cadence is longer than the required response window.	Verify the current plan’s actual check interval and whether custom schedules are available.
History is missing for an older change	The plan’s snapshot retention period has elapsed or the service stores only certain snapshots.	Confirm the retention duration and export or archive requirements before relying on monitoring for long-term records.
Integration does not appear in settings	The integration may be plan-gated, renamed, or not generally available.	Check the current plan matrix and vendor support, especially for Teams availability.

10. Performance, reliability, and cost considerations

• Frequency drives workload. More frequent checks across more pages increase usage or require a higher tier. Compare vendor-defined quotas rather than assuming a check means the same thing everywhere.
• Dynamic pages create noise. Personalized content, animation, ads, clocks, and inventory changes can create irrelevant alerts. Selective rules can reduce noise, but they require validating that important changes remain visible.
• Access can fail independently of configuration. A site may block automated traffic, alter login requirements, or change its markup. A monitor should be reviewed when failures begin, especially for important pages.
• History is a cost decision. If you need evidence for months, compare published retention and export options rather than choosing solely by page capacity.
• Plan terms are volatile. Pricing, frequencies, quotas, integrations, and feature gates can change. Confirm current terms before purchase.
• There is no verified head-to-head benchmark here. The cited vendor pages establish their own published features and terms, not comparative detection accuracy, uptime, or reliability.

11. Recommendation by use case

• Investigate Hexowatch if you need to compare its broad list of monitoring types, particularly visual, technology, source-code, availability, price, WHOIS, sitemap, API, backlink, or RSS monitoring.
• Investigate ChangeTower if you need a small set of page monitors, selective or AI criteria-based alerts, dated snapshots, and team workflows; check the exact plan and current integration availability.
• Use a screenshot API as a companion if your workflow needs a fresh image or PDF capture to attach to a report or application. ScreenshotNeo is the alternative to try first for this separate capture task because it removes common overlays before capture, bills only clean shots, and has a free monthly allowance.

12. FAQ

Which website change monitoring tool is better?

Neither is a universal winner based on the published evidence. Choose according to the change types, check cadence, history, and alert workflow you need.

How often does ChangeTower check a page?

The current pricing page lists daily checks on Free and Lite, hourly checks on Essential, and checks every 20 minutes on Business. Confirm current terms because vendor pages have not always agreed.

Can Hexowatch monitor visual changes?

Yes. Visual monitoring is explicitly included in Hexowatch’s published monitoring types. The exact mode and plan details should be checked on its current product pages.

Does ChangeTower have a free plan?

Yes. Its pricing page lists a free plan for three pages checked daily.

Do these services require code on the monitored website?

They describe external monitoring that does not require adding a tag to the target website. Access and automated-traffic restrictions can still affect particular pages.

Does ScreenshotNeo detect scheduled page changes?

ScreenshotNeo is a screenshot API and MCP server for capturing pages; use a change monitoring service for scheduled change detection and alerts.
