End-to-end application reliability, right inside your workflow

Transform your development workflow with a code-based testing, monitoring, and observability process that's programmable, extensible, and dependable.

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.

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.
