ChangeTower

ChangeTower is a web-page monitoring service, with a browser extension for creating monitors from an open page. It suits people tracking selected pages for changes, including some pages behind a login. Its appeal is the combination of focused checks and dated snapshots; the trade-off is that check speed, history and team capacity are plan-dependent.

Overview

Users can set criteria for alerts, including describing desired changes in plain language for AI monitoring. Selective checks can focus on a page section or element rather than every edit, while snapshots provide a dated record. Manual replay of sign-in and other recorded steps supports monitoring some authenticated pages. None of these features helps when a site blocks automated traffic outright: ChangeTower says such pages cannot be monitored, citing X, LinkedIn, Facebook and Instagram.

The browser extension creates a monitor from the page currently open, a useful shortcut for tracking pages encountered while browsing. The service is available as a web app and extension.

Key features

Targeted monitoring and alerts

AI monitoring is included on Lite and can use plain-language criteria to identify changes worth alerting on. Essential adds section monitoring, and Business adds element monitoring. This progression makes the lower plans better suited to simpler page-level checks, while teams that need to suppress noise from unrelated page edits must move up a tier. Email notifications are included with Lite; Business and Enterprise add Slack, webhooks and MCP. The native Microsoft Teams integration is in development.

History, access and security

Snapshot history ranges from 30 days on Free and Lite to 60 days on Essential and six months on Business; Enterprise retention follows the customer's policy. Accounts support multi-factor authentication. Enterprise adds SAML single sign-on through Microsoft Entra ID or Google Workspace, and buyers can request a completed security questionnaire. Account data, alerts and snapshots are stored in the United States and are visible to workspace members according to their roles.

ChangeTower says support replies within one business day on every plan. Enterprise also includes dedicated support and onboarding.

Pricing

The free plan costs nothing, with no card required. It allows 3 pages, daily checks and 30 days of snapshot history. That is a useful way to start a small monitoring routine, but the low page cap and daily cadence limit its use for broader or time-sensitive tracking.

Lite costs $12 a month and includes 25 pages, one additional team member, checks every 24 hours, 30 days of history, AI monitoring and email notifications. It fits an individual who wants more pages and alert criteria than Free provides, but daily checks and short retention remain constraints.

Essential costs $36 a month, with 100 pages, three additional team members, hourly checks, 60 days of history, section monitoring, custom schedules and user interactions. It is the more practical choice for teams that need targeted checks and more frequent updates; it still lacks Business's element monitoring and faster cadence.

Business costs $78 a month. It includes 200 pages, five additional team members, checks every 20 minutes, six months of history, element monitoring, Slack, webhooks and MCP. This is aimed at organizations needing faster checks, longer records and more notification routes, though its fixed page and member allowances may not suit larger deployments.

Enterprise has custom pricing based on page count. It offers custom page and member counts, domain scanning, full-page archiving, multi-region monitoring, multiple workspaces, review workflows, SAML SSO, dedicated support and onboarding. Those controls make it the tier for large teams with specific scale or governance needs, rather than a default upgrade for smaller groups. The paid plans have a 5-day trial.

Platforms

ChangeTower runs on the web and as a browser extension. The extension can start a monitor from the current page; the service's web and extension availability does not change the automated-traffic blocking limitation.

Who it's for

Lite is positioned for individuals, Essential for teams, Business for organizations and Enterprise for large teams. In practice, the choice turns on how many pages and members need access, how quickly a change must be detected, and how long snapshots should remain available. Competitor tracking is a natural use, but the blocking limitation rules out sites that refuse automated checks.

Pros and cons

• Pros: Plain-language AI criteria and selective section or element checks can reduce irrelevant alerts.
• Pros: Manual replay of recorded actions supports monitoring some pages behind a login.
• Pros: Snapshot retention scales up to six months on Business, with Enterprise retention set to customer policy.
• Pros: Multi-factor authentication is supported across accounts, with SAML SSO and a security questionnaire option for Enterprise buyers.
• Cons: Checks range from daily on Free and Lite to every 20 minutes on Business, so faster monitoring costs more.
• Cons: Free and Lite retain snapshots for only 30 days, which may be too short for longer-term comparisons.
• Cons: Sites that block automated traffic outright cannot be monitored, including the named social platforms.
• Cons: Slack, webhooks and MCP are limited to Business and Enterprise; the native Teams integration is still in development.

Alternatives

For a broader set of options, see Competitive Intelligence Software. Choose Owler instead if its free Community membership, sample of sales intelligence and business information, or wider mobile and API platform coverage better fits the job. Adbeat is an alternative for readers whose priority is viewing and saving ad creatives, with a free Basic plan and a Standard plan priced at $200 a month on yearly billing. AppTweak may fit app-store intelligence needs better, with a free starter plan offering three seats, past-month historical data and download and revenue estimates.

Compint is another option: its Premium plan costs $18 a month for five users, unlimited competitors, unlimited website and news monitoring, and email, Slack and Teams integrations. Fluxguard may suit readers who need site monitoring with custom page filters and network blocks; its Standard (Periscope) plan costs $110 a month for 25 sites monthly and three users. NerdyData is worth considering for technology research, with a free account offering up to 500 rows per report and a free API account.

RivalBeam offers a free plan with one competitor tracked, five monitoring channels and a weekly email digest, making it a different option for readers starting with a narrow competitor set. SiteGauge has a free plan with five monitors, 150 checks per month, daily checks and 30-day change history; consider it if those limits suit your monitoring needs.

Verdict

Choose ChangeTower if you need configurable monitoring of selected web pages, snapshots and a clear path from individual use to larger-team controls. Its strongest reason to buy is the combination of selective checks, authenticated-page workflows and increasingly frequent checks across the paid tiers. Look elsewhere if your target sites block automated access, or if you need faster checks, longer history or broader team capacity without moving to a higher plan.
