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.

Detect downtime faster with proactive synthetic monitoring

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.

Communicate efficiently by integrating alerts and status pages into your workflow

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.

Resolve errors with complete clarity before customers are even aware

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

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

Checkly made it easier for us to simulate real user behavior and detect failures early in the process.

Checkly is super easy to use and fits perfectly in our toolchain.

We monitor our Vercel projects on preview and production to catch issues earlier and we can trust that we are the first ones to know about problems in production.

"Checkly CLI has enhanced our engineering team's ability to quickly build, validate and deploy an entire suite of checks from their local development environment."

"We've been using Checkly for the past months. It's been phenomenal. Super easy to get setup, works flawlessly and intuitively. The team are super receptive & quick to help"

"Checkly is a fabulous developer tool! The flexible features and developer-friendly API made the integration super easy. Bonus: their support is super friendly and knowledgeable!"

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

"Checkly has helped us save engineering resources and expenses. The number of our customer support tickets are then reduced because the customer is already proactively informed about problems without having to report the issues themselves."

"A real advantage that Checkly gives us is that we’re not waiting for our users to report an issue with a product, or waiting on a staff member to file a ticket—Checkly gives us real-time feedback on what is and isn’t working." 

"With the Checkly CLI... not only has the check administration become easier, but more people feel empowered to add and edit more checks, which has ultimately improved our monitoring efforts."

"It only took our team a day or two to evaluate Checkly and determine if it was the right fit for us. It only took me a few minutes to get a login check working and determine if we could login and validate that the CDN was up."

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