Is Sitecomb a replacement for Lighthouse?
Not for developers tuning speed: Lighthouse goes deeper there. Sitecomb adds what Lighthouse doesn't list: email anti-spoofing, domain expiry, privacy and cookie notices, contact details and AI crawler rules.
Is PageSpeed Insights free?
Yes, and it needs no sign-up.
Why would I pay $4.99 if PageSpeed is free?
To skip running several tools and translating each result. The report puts six areas in one place, with a plain fix for each problem.
Does Sitecomb change my website?
