What does Lemwatch monitor?

Lemwatch runs 20+ automated checks per site: uptime, response time, SSL/TLS expiry, domain expiry, DNS changes, sitemap health, broken links, content changes, SEO audits, mobile usability, security headers, and more.

Yes. The free tier monitors up to 5 sites. Pro is $19/month for 50 sites and Agency is $59/month for 100 sites, both with full feature access.

How is Lemwatch different from UptimeRobot or Pingdom?

Lemwatch bundles uptime, change detection, SEO audits, security scans, and a public API in one platform — features competitors charge separately for. It also includes team workspaces, white-labelled status pages, and a webhook system out of the box.

Does Lemwatch send alerts?

Yes. Lemwatch supports email, browser push, webhooks, and per-site notification routing so the right person hears about the right incident.

Is there a public API?

Yes. Pro and Agency plans get a public REST API with webhooks for sites, checks, incidents, and reports.

Hysteresis band explained

Lemwatch requires response time to fully clear a threshold before recovering, preventing oscillation alerts.

Quick answer

If your alert threshold is 2000ms, Lemwatch won't mark the site "recovered" until response time drops below 1600ms (2000 − 20% band). This stops jittery pages toggling between degraded and healthy.

What it does

Adds a 20% clearance band below every threshold
Requires the metric to fully cross the band before flipping status
Applies to response time, TTFB, LCP, INP, and health score
Prevents "recovered → degraded → recovered" alert loops

Where to find it in Lemwatch

Site → Settings → Alert accuracy → Hysteresis band.

How to tune it

Open the site's Alert accuracy settings.
Adjust the Band width (default 20%) — wider = more stability.
For very stable sites, drop to 10%.
For noisy sites near threshold, raise to 30%.
Save.

FAQ

Does this delay recovery alerts?

Only when the metric hovers right at the threshold. Clear recoveries fire immediately.

Does it apply to uptime status?

No — uptime is binary. Hysteresis is for continuous metrics.
