European company. American infrastructure.

Checkly is based in Berlin. They're a genuinely European company. But their infrastructure runs on AWS, which is owned by Amazon, a US company subject to the CLOUD Act. Being a European company doesn't change the fact that your monitoring data sits on American-owned servers where US authorities can compel access.

Larm runs on EU-owned infrastructure under EU jurisdiction. Not "EU region" on an American cloud. Actually European-owned. If your team cares about GDPR, DORA, or NIS2, that distinction matters more than where the company is headquartered.

Checkly is built for developers. That's by design. Monitoring-as-code, Playwright scripts, CI/CD integration. If your entire team writes code and wants checks defined in TypeScript, it's a good fit. But most teams have people who aren't developers and still need to understand if things are working.

Larm is built so that anyone on your team can set up a monitor, read a dashboard, and understand what's happening. No code required, no CLI to learn. Your developers will feel at home, and so will your product manager, your support lead, and your founder who checks the dashboard at 6 AM. Monitoring shouldn't require a pull request.

Checkly's Starter plan gives you around 50 checks for $24/mo. Their pricing is based on check runs, which means your bill can fluctuate depending on how often your checks run and how many locations you use. More checks, more locations, more runs, higher bill.

Larm Pro is $19/mo for 100 monitors with 1-minute checks from all probe locations. Flat rate. Your bill doesn't change based on how many locations you check from or how often your monitors run. You know what you'll pay before you sign up.

Checkly doesn't offer status pages. If you need one, you're buying a separate product. Statuspage at $29/mo, Instatus, or something else. That's another vendor, another integration, and another bill for something that should just come with your monitoring.

Larm includes a status page on every plan, including free. It's connected to your monitors and updates automatically when something goes down. Pro adds custom domains and removable branding. You don't need to buy a second product to tell your users what's happening.

Checkly sends notifications when checks fail. Email, Slack, PagerDuty, OpsGenie. But it's monitoring-only. The alert fires and then it's on you to manage the incident in another tool. There's no built-in incident workflow, no escalation, no status page to update.

Larm connects monitoring to alerting to status pages in one product. When something goes down, your team gets notified, your status page updates, and you can manage the incident without switching tools. It integrates with incident.io and Grafana IRM if you need deeper incident management, but the basics are built in.
