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 happens when an integration fails to deliver?

Lemwatch retries failed webhook deliveries up to 5 times with exponential backoff, then marks the channel as degraded and emails the org owner.

Quick answer

On a non-2xx response Lemwatch retries the delivery 5 times with exponential backoff (30s → 15min). If all retries fail the channel is marked degraded, and the org owner receives an email with the failing endpoint and the last error.

Retry schedule

Attempt 1 — immediate
Attempt 2 — +30 seconds
Attempt 3 — +2 minutes
Attempt 4 — +5 minutes
Attempt 5 — +15 minutes

FAQ

Do you retry 4xx errors?

No — 4xx means your endpoint rejected the payload; fix the config and re-test.

Can I replay a failed delivery?

Yes — click Replay on any log row.
