ABOUT

What is Checkly?

Checkly is a code-first synthetic monitoring platform built around Playwright for browser checks and simple HTTP requests for API checks. Monitoring is defined as code (Pulumi or Terraform), making it easy to integrate into CI/CD pipelines. It targets developer teams that want to catch regressions before real users are affected.

BEFORE YOU SIGN UP

What you should know

✓

Playwright-native monitoringBrowser checks run on real Playwright scripts, so teams can repurpose their existing e2e test suites as synthetic monitors with minimal changes.

✓

Monitoring as codeDefine checks with Pulumi or Terraform and version-control them alongside application code, enabling GitOps workflows for monitoring.

△

Free tier is limited10k API checks and 1,500 browser checks per month is enough for experimentation but small for any production deployment with multiple endpoints.

Costly at scaleBrowser checks consume credits quickly and pricing can become expensive compared to simpler uptime-only alternatives for teams running many checks.

COMMUNITY

From the forums

Users on r/devops praise the Playwright-native approach, which lets teams reuse existing e2e test suites as monitoring checks. The IaC integration with Pulumi and Terraform is noted as a significant advantage over traditional point-and-click monitoring tools. Criticism focuses on the relatively high cost at scale and the limited free tier compared to simpler uptime monitors.
