Calibre
Web performance monitoring your whole team can act on

Calibre is a web performance monitoring platform that combines real user monitoring (RUM), Google CrUX data, and synthetic page speed tests in a single dashboard. It surfaces high-impact performance issues and tracks Core Web Vitals to help teams improve site speed and search rankings. It integrates with developer workflows via CLI, Node.js API, CI/CD pipelines, and PR reviews.
Calibre collects data from real user monitoring, Google CrUX, and scheduled synthetic tests, then surfaces actionable insights and integrates into existing dev and reporting workflows.
