# Lemwatch vs Dotcom-Monitor

> An honest, like-for-like comparison between Lemwatch and Dotcom-Monitor — what each one monitors, how alerts work, and what you actually pay at scale.

## What this comparison covers

 This page lines up Lemwatch and Dotcom-Monitor on the four dimensions that actually matter when you're picking a website monitoring tool: **what each one checks**, **how alerts are routed**, **what you pay at real scale**, and **which integrations are built-in versus add-on**. No marketing fluff — just the operational differences a team feels in week two.

### Coverage at a glance

- Uptime monitoring — both tools cover the basics; the difference is retry/confirmation logic and how false positives are suppressed.

- Performance — Lemwatch tracks Core Web Vitals (LCP, CLS, INP, FCP, TTFB) continuously, not just on demand.

- SEO health — sitemap validation, indexation tracking, structured-data checks, mobile-friendly audits.

- Security — SSL/TLS expiry, security-header grading (A–F), exposed-port and malware cross-reference.

- Content + visual change — annotated screenshots and content diff, not just byte comparison.

- Domain + DNS — RDAP-first expiry detection and A/MX/NS/CNAME change alerts.

### Pricing at real scale

 Dotcom-Monitor's pricing varies by usage; Lemwatch is flat per-site. Pro is $19/month for 50 sites, Agency is $59/month for 150 sites. There are no per-check fees, no per-host fees, and no contract minimums. The free tier covers 10 sites with every check enabled — useful enough to make a real call before you upgrade.

### When Dotcom-Monitor is the right pick

 If your team is already standardized on Dotcom-Monitor for adjacent telemetry (logs, APM, RUM) and you need website monitoring inside that same ecosystem, the integration tax of bringing in a separate tool may outweigh Lemwatch's coverage advantage. For everyone else — marketing sites, e-commerce, client portfolios, SaaS teams — Lemwatch ships the same uptime + performance coverage plus the SEO, security, and change-detection layers Dotcom-Monitor doesn't run by default.
