01
No account, no install, no tag on your site. Enter any homepage address and the probes start immediately — from our servers, not your browser.
02
Results arrive in three phases — network & DNS, security & content, AI & privacy. The report builds live in front of you instead of landing as a static PDF.
03
One overall score, split into site quality and infrastructure. Every row states what was checked, what was found, and what to do — pass, warn, or fail, explained in plain language.
04
Create a free account and the same checks run daily. Score history, trend deltas since the last check, and early warning before an SSL expiry or a blacklist hit becomes a client call.
Also includes — DNS records · Domain expiry · Technology detection · Tracking inventory · Social meta tags
Add client domains to a portfolio dashboard and getButterfly IO runs the full health check daily. Trend deltas show what moved since yesterday, and portfolio alerts surface cross-site issues — SSL expiring, slow responses, missing consent, malware listings — before the client notices.
Free plans monitor 1 site; Pro takes 10 and Agency 100+.
01
Fast probes over curl and HTML parsing. Honest positioning: network and markup intelligence, not pixel-perfect rendering audits — and results in seconds, not minutes. Open DNS blacklists, URLhaus, RDAP, DoH, crt.sh, and proprietary heuristics.
02
A performance lineage and a security lineage in a single report — plus WordPress-specific probes. Not just a Lighthouse number: site quality weighted 60%, infrastructure 40%.
03
DNS snapshot diffs, content hash changes, TTFB trends. For watchlist sites, the question isn't just "is it healthy?" — it's "what changed since yesterday?"

Partially. We measure what the server and network reveal — TTFB, page weight, compression, HTTP version — not lab rendering metrics like LCP or CLS. Think of it as everything Lighthouse doesn't cover, plus the parts of speed it does.
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.
