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.

Uptime Monitoring

How LemWatch checks if your website is online and responding.

Uptime Monitoring

How It Works

LemWatch sends HTTP requests to your website at regular intervals from multiple locations. If your site returns a non-2xx status code or doesn't respond within 30 seconds, it's marked as potentially down.

Downtime Confirmation

To prevent false positives from temporary network blips, LemWatch confirms downtime with consecutive failed checks before alerting you. Configure the threshold in Settings → Alert Preferences.

Check Intervals

Plan — Interval —

Free — Every 60 minutes —

Pro — Every 15 minutes —

Agency — Every 5 minutes —

Enterprise — Every 1 minute —

What Gets Checked

HTTP status code — We expect 2xx responses
Response time — Measured in milliseconds
SSL certificate — Validity and days until expiry
DNS resolution — Can we resolve your domain?
Content verification — Optional keyword check to verify page content loaded correctly

Uptime Percentage

Calculated over rolling 24h, 7-day, and 30-day windows: (total_minutes − downtime_minutes) ÷ total_minutes × 100

Maintenance Mode

When you're doing planned maintenance, enable Maintenance Mode to suppress alerts. See Maintenance Windows for details.

Response Time Tracking

LemWatch tracks response times over time so you can spot degradation trends before they become outages. A gradually increasing response time often predicts upcoming issues.
