Checkly is a synthetic monitoring platform founded in 2018 by Hannes Lenke and Tim Nolet, headquartered in Berlin, Germany. The company has raised roughly $32 million in funding, including a 2024 Series B led by Balderton Capital, and employs around 50-58 people.
Checkly runs scheduled API and browser checks from up to 22 global locations to monitor the uptime and correctness of websites and APIs, built natively on Microsoft's Playwright framework so teams can reuse existing end-to-end tests as production monitors.
Checkly combines Playwright-powered browser checks with HTTP API checks, both defined as code and deployed through CI/CD pipelines under a monitoring-as-code philosophy, along with public status pages and alerting integrations.
In early 2026, Checkly added Rocky, an AI agent that automatically triages check failures and analyzes network traces to surface likely root causes, reducing manual investigation time during incidents.
Checkly offers a free Hobby plan (10 uptime monitors, 1,000 browser checks, 10,000 API checks/month). Paid plans scale usage and locations: Starter is around $24/month and Team is around $64/month, both billed annually, with custom Enterprise pricing for larger organizations.
