About Checkly

Checkly is a sophisticated monitoring platform designed for modern engineering teams to ensure web application reliability through API and synthetic monitoring. By leveraging industry-standard frameworks like Playwright and Puppeteer, it enables developers to execute complex browser-based tests across global locations. Its primary differentiator is the seamless integration of code-centric monitoring into existing CI/CD pipelines, allowing teams to catch regressions before they impact end-users. Checkly provides high-fidelity observability, helping developers proactively maintain performance, uptime, and functional integrity for complex, dynamic web applications and APIs.

Who Is This For?

Best For

Frontend Engineers

They can use familiar Playwright syntax to write end-to-end tests that double as production monitors.

DevOps Engineers

The platform integrates perfectly into infrastructure-as-code workflows and automated deployment pipelines.

QA Automation Engineers

It allows for the reuse of existing test suites to monitor critical user journeys in production environments.

Not Ideal For

Non-technical Stakeholders

The platform requires coding proficiency in JavaScript or TypeScript, making it inaccessible for non-developers.

Legacy Enterprise IT

Organizations relying on traditional, non-web protocols may find the tool's focus on modern web stacks too narrow.
