Nine tools, two layouts each
Every preview is a real, working embed from
app.speedtest.doctor. Click Run on any
widget to test it. Tool widgets use a rate-limited demo key on this page only —
sign up for your own key for production embeds.
SSL / TLS check
Shows certificate validity, issuer and expiry for any hostname so users can verify HTTPS is configured correctly.
Ping
Reports round-trip latency and packet loss to a host — a quick way to confirm reachability from the visitor's network.
DNS benchmark
Compares resolver response times across public DNS providers so users can spot slow or misconfigured DNS.
HTTP headers
Fetches response status and security-related headers (HSTS, server, cache) for troubleshooting site configuration.
Port scan
Checks TCP reachability on common ports — useful for verifying firewalls, mail servers or web services.
WHOIS lookup
Returns domain registration details so visitors can confirm ownership, registrar and expiry dates.
Traceroute
Maps the hop-by-hop network path to a target — helpful when diagnosing routing or latency issues.
Connection diagnose
Runs a speed test and returns a plain-language verdict with likely causes — the same engine that powers the Doctor.
