The free instant scan is always available — no account required. Basic and Pro are billed monthly — cancel anytime, no contract.
Those measure how one page renders, once, in a lab. IO checks the things they never see — SSL and domain expiry, DNS, blacklists, email authentication, exposed files, pre-consent cookies — and re-checks them every day. Page speed is one of 25+ categories here, not the whole story.
No. Every check runs from our servers against your public site — no plugin, no JavaScript tag, no agent, nothing to slow your pages down. It works on any stack, hosted anywhere.
Instant scans analyze publicly reachable responses from your site and keep the report so you can share it. Nothing is shared with third-party analytics services — the probes are ours.
Especially well. Alongside the standard checks, WordPress sites get dedicated probes: version exposure, login hardening, user enumeration, and common misconfiguration signals.
Daily. Every site on your watchlist gets the full health check every day, with score history, trend deltas, and portfolio alerts when something moves the wrong way.
One scan, no signup, a prioritized fix list in under a minute.
