Better Stack vs Checkly

Better Stack is an observability platform built by a Prague-based company of the same name. It started as two products, Better Uptime and Logtail, and now combines uptime monitoring, incident management, on-call scheduling, status pages and log and metrics management (Telemetry) under one account and one interface.

Monitors check HTTP endpoints, keywords, ports, DNS, SSL certificates and cron heartbeats from multiple regions, with check intervals down to 30 seconds on paid plans. Alerts go out by phone call, SMS, email, Slack and Microsoft Teams, escalate through on-call rotations, and open incidents that can update a hosted status page automatically. The telemetry side is built on ClickHouse: logs and metrics are queried with SQL, followed in live tail and turned into dashboards, with OpenTelemetry and common log shippers supported. The free plan covers 10 monitors, a status page and a small log allowance; uptime is billed as a monthly plan, while logs and metrics are usage-based per GB.

It fits startups and small to mid-size engineering teams that would otherwise pay for Pingdom, PagerDuty and Statuspage separately, and its interface is widely praised. It is not as deep as Datadog for APM, profiling and enterprise security, and PagerDuty remains more sophisticated for complex on-call and event routing. Uptime Kuma is the free self-hosted alternative for monitoring only, and Grafana Cloud is the main competitor on cost-efficient logs and metrics.

Checkly is a synthetic monitoring platform from Berlin built on the idea of monitoring as code. Engineering teams write API checks and browser checks in JavaScript or TypeScript, using Playwright for browser flows, keep them in the same repository as the application, and deploy them with the Checkly CLI or Terraform.

The same checks run in CI against preview deployments before a release and then continuously from global locations after it, so a broken login or checkout flow is caught by a test first and by monitoring second. Assertions, retries, alert channels such as Slack, PagerDuty and email, multistep API checks and heartbeat monitors are available, and traces connect a failed check to backend spans through OpenTelemetry. A free Hobby plan includes a monthly quota of API and browser check runs; Starter and Team plans add runs, locations and collaboration, and Enterprise adds SSO and private locations inside your own network.

Checkly fits teams that already write Playwright tests and want one source of truth for end-to-end testing and production monitoring. It requires coding and is not a full observability suite, so it is a poor fit for non-technical teams who only want uptime pings. Better Stack and UptimeRobot are simpler for basic uptime and status pages, Datadog Synthetics suits teams already on Datadog, and Grafana Cloud offers synthetic monitoring inside its own stack.
