Hey Indie Hackers!
At TestingBot, we help developers and QA teams automate testing across browsers and devices. Today, we’re launching a free tool that’s aimed at every indie hacker who wants their website to load faster and rank better on Google.
You enter a URL, and we’ll return Critical CSS – the minimal CSS needed to render above-the-fold content. This is the CSS you should inline in your <head> to drastically improve load time and Core Web Vitals like Largest Contentful Paint (LCP) and First Contentful Paint (FCP).
Speed = SEO: Google uses Core Web Vitals as a ranking factor. Critical CSS can shave seconds off load time.
Better UX: Visitors see usable content faster, which lowers bounce rates.
Zero setup: Just paste a URL – no downloads, no installs, no accounts required.

We’re offering this 100% free for the community to help more websites load faster and perform better. It works great for marketing sites, blogs and e-commerce stores.
Happy optimizing! 🚀
