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.

Monitor Grouping & Aggregate Status

Group sites by tag and see aggregate uptime, health, and incident counts across product lines or clients.

Monitor Grouping & Aggregate Status

Group sites by tag and view aggregate status at a glance. Essential for agencies managing dozens of clients and for product teams monitoring multiple environments (production, staging, dev).

How It Works

Assign one or more tags to each site — e.g., Production, Client: Acme, Region: EU. Tags are freeform; you can create them on the fly.
Switch to Group View on the dashboard (top-right toggle, or press g then v).
Sites are grouped by their primary tag with an aggregate row on top: total count, up/down/paused split, average uptime %, worst health score, and open incident count.

Aggregate Metrics

Uptime % — weighted average across all sites in the group over the selected time window
Health score — the minimum score in the group (surfaces the weakest site first)
Open incidents — count of currently-firing incidents across the group
Response time — median across all sites, useful for spotting regional slowdowns

Multi-Tag Sites

A site with multiple tags appears in each group. The aggregate row deduplicates on site ID so you don't double-count uptime.

Group-Scoped Reports

When you have Group View enabled, PDF reports and CSV exports respect the current group filter. Great for client-facing weekly summaries — one PDF per tag, sent automatically via Reports → Scheduled Delivery.

FAQ

Can groups be nested? Not yet — use compound tags (Client:Acme:Production) as a workaround. Nested groups are on the roadmap.

Can I rename a tag across all sites? Yes — Settings → Tags → Rename. The change propagates instantly.
