Checkly

Checkly, founded in 2018, builds a monitoring-as-code platform designed to give developers control over application reliability from pull request to post-mortem. The Checkly Platform unifies testing, monitoring, observability, status pages and incident communication within a single developer-oriented workflow, combining proactive issue detection with intelligent root cause analysis. A separate product, Automated Status Pages, handles stakeholder communication during incidents.

The company's tooling is built on industry-standard technologies, notably Playwright for browser automation and OpenTelemetry for instrumentation, and covers domains including synthetic monitoring, application monitoring and automated testing. Its stated philosophy is developer-first: tools are aimed at developers rather than operations teams, with the explicit goal of keeping engineers in their existing development workflow without context-switching. The company frames its work around helping teams build confidently and ship continuously.

Checkly reports adoption by thousands of developers, with customers including LinkedIn, Vercel, 1Password and CrowdStrike. It operates in the software development, DevOps, application reliability and SaaS sectors.
