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 is Lemwatch different from Checkly?

Checkly focuses on synthetic monitoring and API checks for developers. Lemwatch is an all-in-one platform covering uptime, performance, SEO, and security monitoring — better suited for agencies, marketers, and site owners who need a complete picture.

Does Lemwatch support API monitoring like Checkly?

Yes! Lemwatch includes API endpoint monitoring with custom headers, expected status codes, and response time tracking. While Checkly offers more advanced scripted browser checks, Lemwatch covers the most common API monitoring needs.

Can I migrate from Checkly to Lemwatch?

Absolutely. Export your monitored URLs from Checkly, create a Lemwatch account, and add your sites. Migration typically takes under 15 minutes.

Is Checkly better for developers?

Checkly is developer-focused with Playwright-based browser checks and monitoring-as-code. If you need scriptable synthetic tests, Checkly is stronger. If you need broader monitoring (SEO, security, performance), Lemwatch is the better choice.

Which is more affordable?

Lemwatch's Pro plan at $19/mo includes 50 sites with full monitoring. Checkly starts at $30/mo for their Team plan. For most use cases, Lemwatch offers significantly more value per dollar.

Does Lemwatch offer browser-based checks?

Lemwatch integrates with Google's PageSpeed Insights API for real browser-based performance data including Core Web Vitals, rather than running custom Playwright scripts like Checkly.

How to Switch from Checkly

Migration takes less than 15 minutes. Here's your step-by-step guide.

Export your sites from Checkly

Pull your monitor list out of Checkly — most tools offer a CSV export, or you can copy the URLs straight from the dashboard.

Create your free Lemwatch account

Import and map your monitors

Paste or bulk-upload the URLs you exported from Checkly. Lemwatch auto-detects the platform, SSL state and sitemap for each one.

Rebuild your Checkly alert routing

Point alerts at the same channels you use today — email, Slack, Discord, Teams, PagerDuty or webhook — then set thresholds to match your Checkly config.

Run both in parallel, then cancel Checkly

Give it one billing cycle. Once Lemwatch alerts match Checkly's on the same incidents, cancel and keep the history in Lemwatch.
