Direct answer
How much does ChangeTower cost?
ChangeTower runs a free tier plus paid plans, and the practical cost driver is not the headline price — it is how many URLs you watch and how often each one is checked.
- Change-detection tools price on monitored-page count and check frequency, so a low entry price can still be expensive across a client portfolio.
- Check the shortest interval on the plan you are pricing — hourly versus daily changes the tool's usefulness for pricing or stock pages entirely.
- Always price the plan you would actually run, not the entry tier, before comparing vendors.

Why Teams Choose LemWatch Over ChangeTower
Visual monitoring is powerful. Visual monitoring with full site health context is transformative.
Free vs $12+/Month
ChangeTower charges $12-$78/month (Lite to Business) for change detection only. LemWatch includes visual monitoring free alongside uptime, performance, SEO, and security.
Uptime + Performance Built In
ChangeTower can't tell you if your site is down or slow. LemWatch monitors uptime with 1-min checks and Core Web Vitals alongside visual changes.
Security Monitoring Included
SSL certificates, security headers, DNS monitoring, and vulnerability detection — all included. ChangeTower focuses purely on content changes.
Watch Zones — Free
Monitor specific page regions at no cost. Draw rectangles on any area to focus monitoring. ChangeTower doesn't offer region-specific visual monitoring.
Performance Context
See why visual changes happened — correlated with performance drops, uptime incidents, and content modifications on a unified timeline.
All-in-One Platform
Replace ChangeTower + your uptime monitor + performance tool + SEO checker with one affordable platform that connects everything.
ChangeTower Limitations

- No watch zones, blink mode, or slider comparison
LemWatch Advantages
- Free forever tier with full visual monitoring capabilities
- 1-minute uptime checks with incident tracking and SLAs

Compare the workflow, not a stale checklist
Product availability, feature names and plan limits change. Use the current documentation for Lemwatch and ChangeTower to validate the capabilities that matter to your team.
What must the check represent: a public page, an API, or a complete authenticated journey?
Who will configure and own it: a non-technical team, developers, or both?
Which evidence do you need after an alert: request context, a script result, logs, or a customer-facing status?
This page does not treat a feature label as a permanent product fact. Confirm current coverage, implementation requirements and commercial terms with each provider before purchase.
