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.

How does Lemwatch track SSL certificate expiry?

Lemwatch reads the TLS certificate on every uptime check and starts alerting 30, 14, 7, and 1 day before expiry so you never ship an expired cert.

Quick answer

During every HTTPS uptime probe we read the leaf certificate, extract the notAfter date, and schedule reminders at T-30, T-14, T-7, and T-1 day. Auto-renewed certs simply refresh the countdown.

What we surface
