Three checkups, kept in one calm place
Most tools make you stitch together three different services. WebsiteHeart runs the same three checks side by side, so a dip in one always shows you the full picture.
SEO checker
A full read of your page — titles, headings, images, links, and the technical basics — with the fixes worth doing first.
Try the SEO checker →Performance testing
Load times, page weight and Core Web Vitals, plus the exact files that are slowing your visitors down.
Try the performance test →Uptime monitoring
Check your site the moment you need to know — is it up, how fast did it answer, and did anything redirect on the way?
Try the uptime check →Trusted to keep watch, at scale

Questions people usually ask
If you're wondering something that isn't here, our team answers real questions from a real inbox — no bots.
How is this different from running three separate tools?
Instead of jumping between an SEO tool, a speed tester and a status page, WebsiteHeart keeps all three checks in one place with one consistent report — so you can see whether a slowdown, a ranking problem and an outage are actually the same issue.
How do the checks work?
You paste a URL and we check it on the spot. We read your page the way a search engine would, download it the way a visitor would, and report exactly what we found. Nothing is stored between checks.
Where do the Core Web Vitals come from?
FCP, LCP, CLS and TBT can only be measured by a real browser painting your page, so we ask Google PageSpeed Insights for those four numbers. Everything else on the report we measure ourselves.
Can I check more than one website?
Yes — as many as you like. There is no account and nothing to set up, so you can check a different URL whenever you want.
Do I need to install anything on my server?
No. WebsiteHeart checks your site the same way a visitor or search engine would — from the outside in. Just paste your URL.
Is it free?
Yes. All three checks are free to run. To keep the service responsive for everyone there is a limit on how many checks one visitor can run per hour.
