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.

What conditions and operators can I use in Alert Rules?

Rules support metric-based conditions (uptime, response time, SSL, status code, visual diff, SEO score) with numeric, boolean, and change operators.

Quick answer

Supported operators: >, >=, <, <=, ==, !=, changed, increased by %, decreased by %, and for duration. Supported metrics span uptime, response time, SSL days-to-expiry, HTTP status, visual diff %, and SEO score.

Supported metric families

Uptime — status (up/down), consecutive failures
Response time — ms value, % change vs rolling baseline
SSL — days to expiry, issuer change, chain valid
HTTP — status code, response header presence
Visual — diff %, region-scoped diff, text change
SEO — score delta, title/meta change, sitemap 404s
DNS — record change (A / MX / NS / CNAME)

Where to find it in Lemwatch

Settings → Alerts → Rules → New rule → Add condition.

How to combine conditions

Add a first condition (e.g. status code != 200).
Click + AND or + OR for more conditions.
Use for duration to require the condition to hold (kills flapping).
Preview against the last 24h of data before saving.

FAQ

What does "changed" mean for numeric metrics?

Any non-zero delta from the previous check. Use % change for smoother triggers.

Can I compare two metrics?

Not yet — every condition compares one metric to a constant.
