What is Checkly?
Checkly is a synthetic monitoring platform built around Monitoring as Code, where checks are written in TypeScript or JavaScript, or uploaded as an OpenAPI spec, and stored in Git alongside application code. Founded in Berlin, Germany in 2018, it lets engineering teams define API monitors with chained requests and assertions, plus Playwright powered browser checks that simulate real user journeys.
The free Hobby plan includes 10 uptime monitors and thousands of monthly browser and API checks with no credit card required. Paid Starter and Team plans raise those limits, unlock all 22 monitoring locations, and add faster check frequencies, while Enterprise is custom priced. In early 2026 Checkly introduced Rocky, an AI agent that automatically triages failures and helps surface root causes.
