The modern alternative to Assertible for developers

checkly pingdom monitoring dashboard alternative

"Checkly is incredible: It combines Pingdom, Ghost Inspector and Assertible all in the same app, and the insights are much more detailed."

Leo Lamprecht | SVP Product

Why Checkly and not Assertible?

Checkly is built for developers and engineering teams eager to monitor their cloud native applications.

Combined E2E & API checks

Assertible is great when you want to know if your APIs are up. But it doesn’t show you the full picture - whether your UI flows and endpoints are working correctly.

Powerful Synthetics

Monitor your websites with a real Chrome browser. With Checkly you can use JavaScript to code your checks, instead of using a restrictive scripting editor.

Developer-first platform

Use our delightful UI or simply code. Checkly provides powerful API, SDK, and a Terraform provider to enable you to configure your checks via code.

Checkly enables you to create flexible HTTP Checks tailored to your needs.

  • Monitor your API for performance & correctness
