DareBoost

Dareboost tests website speed and analyzes pages. A single run checks a long list of quality controls covering performance, SEO and security, and shows an interactive waterfall of how the page loads, with best practices flagged so a page owner can see what to fix. Beyond one-off tests it offers web performance monitoring with thresholds the user sets to catch regressions or slowdowns, user journey monitoring, mobile website tests, and comparison of two pages or of pages against competitors, all on customizable dashboards with charts. Every feature is also available through an API, and results export as CSV files. It is aimed at front-end and technical teams that want to test, analyze and monitor page speed and user experience from one place. A free account is available, and a demo can be requested.
