Single page tests are powered by a developer-first CLI. Build custom tracking that suits your needs.
Each test comes with a publicly available report page. Share with quality assurance, managers and fellow developers. No log-in required.
Calibre can test from all corners of the globe. Measure the user experience, no matter where your audience is.
Understand how pages perform under a vast array of conditions, often different from your own.
Invoke single-page tests after deployments or in continuous integration. Get rapid feedback whenever you need it.
