Checkly
Monitoring-as-code with Playwright-based end-to-end checks
Checkly is profiled here as a Testing tool for engineering teams. Read about features, pricing, and how it compares to related options in the tools directory.
Description
Checkly is a synthetic monitoring platform that runs end-to-end browser checks and API checks on a schedule from locations around the world. Founded in 2018 by Tim Nolet, it lets developers define monitors as code through a CLI and Playwright scripts, so checks live in the same repository as the application and ship through the same pipeline. When a check fails, Checkly alerts the on-call team and records a trace of the failed run for debugging.
Key Capabilities:
Playwright-powered browser checks that script real user flows against production
API checks that validate status codes, response bodies, and latency on a schedule
Monitoring as code through a CLI that keeps checks in version control
Global check locations that catch region-specific failures and latency
Alerting through Slack, PagerDuty, email, and webhooks on a failed run
Dashboards and traces that show where a failing check broke down See Checkly pricing details
