A new way to detect, communicate, and resolve errors in your APIs

Checkly allows engineering and platform teams to create and maintain synthetic API monitoring across the SDLC at a scale unachievable with traditional platforms. Using a monitoring as code workflow, teams can configure their monitoring, alerting, and tracing right from their IDE

1

With monitoring as code, you can automate your entire monitoring process. Use Playwright, OpenAPI specs, our CLI, or other SDKs to build powerful uptime and end-to-end monitors that you can test and deploy in your CI/CD workflow.

2

When Checkly discovers an error or performance bottleneck in production, teams are immediately alerted in the correct channels with the information they need to fix it. Send text message, update Slack channels, create tickets - all configured right in your IDE.

3

Know exactly what went wrong across distributed systems using Checkly Traces and bubble up key information required for engineering to diagnose the problem and make a fix.
