Our verdict on Checkly
Checkly is a cloud monitoring platform for developers, SREs, and QA teams. It monitors websites, APIs, services, DNS records, TCP endpoints, TLS certificates, scheduled jobs, and network paths from global locations. Browser and Playwright checks support user journeys, while API and multistep checks can include assertions. Teams can also monitor private infrastructure through private locations and manage checks with TypeScript, Terraform, or Pulumi.
The plan structure covers entry-level uptime monitoring through enterprise requirements. Hobby is free and includes uptime and synthetic monitoring with email, Slack, and webhook alerting. Starter costs $24 per month and adds SMS alerting. Team costs $64 per month and includes 22 public locations, all alerting channels, and private locations. Enterprise provides custom solutions, a 1-second maximum frequency, and all alerting channels. The published plan details show the same displayed monthly-equivalent amounts for annual billing on Starter and Team.
Checkly fits engineering teams that want more than basic availability checks, particularly those managing browser journeys, API assertions, response-time thresholds, percentile tracking, SSL expiry, cron jobs, and network endpoints in one platform. Its integrations include Slack, PagerDuty, Opsgenie, Microsoft Teams, incident.io, Rootly, FireHydrant, and Splunk On-Call, alongside email, SMS, phone calls, Discord, and Telegram. Status pages, dashboards, programmable retries, escalation policies, and AI-powered root cause analysis extend the operational workflow. Choose Checkly when code-defined monitoring and varied synthetic checks matter; choose a simpler monitoring product if you only need basic uptime alerts without developer-oriented checks or private locations.
