About
checkiux is a free analysis tool that shows in seconds how fast a website loads and what’s driving its visitors away. Just enter the address and choose mobile or desktop — no sign-up and no card details needed.
Analyses run on Google Lighthouse, the same engine behind Google PageSpeed Insights. Each site is evaluated from four angles: performance, SEO, accessibility and best practices. The report shows your scores, Core Web Vitals metrics and top-priority issues.
Technical reports can be hard to read, so checkiux explains what each issue means in plain language. You can fix the issues yourself or, if you prefer, leave them to the Startiux team. The tool is available in Turkish and English.
