# Website monitoring that covers more than uptime

> Lemwatch runs 20+ automated checks on every site you monitor — uptime, performance, SEO, security headers, SSL, DNS, content changes, broken links, and more — with one alert pipeline and one bill.

## What Lemwatch checks

 Every site you add gets the full battery of checks, not a paywalled subset: uptime and response time from multiple regions, Core Web Vitals, SSL certificate validity and expiry, DNS record changes, security headers, SEO regressions like stray noindex tags or broken canonicals, broken links, content and visual changes, and assertions on the pages that make you money.

## Alerts you can act on

 Failures are confirmed from a second region before anyone gets paged, so a flaky probe doesn't wake you up. When an alert does fire it names the plain-English root cause — expired certificate, DNS change, 5xx from origin — rather than an HTTP code you have to look up. Alerts route to email, Slack, Google Chat, Discord, Teams, webhooks, or the public API.

## Built for portfolios

 Pricing is per plan, not per host or per check, so adding another client site doesn't change the bill. White-label reports, public status pages, team roles and a full API mean the monitoring layer fits into how an agency already works.

## Start free

 The free tier runs the same checks as the paid tiers on a smaller number of sites, with no card required. See the [pricing page](https://lemwatch.com/pricing) for the limits on each plan, or browse [every feature](https://lemwatch.com/features).
