Network diagnostic tools
Everything you need to understand your connection: speed, latency under load, packet loss, DNS, certificates and availability.
Internet Speed Test
Download, upload, ping and jitter
Measure your real broadband speed with a multi-stream download and upload test, plus latency and jitter.
Bufferbloat Test
Latency under load
Compare your idle latency with latency while the line is saturated to reveal bufferbloat that ruins calls and gaming.
Packet Loss Test
Lost packets and stability
Send a burst of probes to measure packet loss percentage, latency and how many probes came back.
Gaming Ping Test
Ping to regional game servers
Measure ping, jitter and loss against Europe, North America, Asia and Middle East regions and get a gaming quality score.
Website Speed Test
TTFB, load time and page size
Enter any URL to measure time to first byte, total load time, page size, DNS and connection time with a performance score.
DNS Leak Test
Is your DNS exposing you?
Detect which DNS resolver answers your queries, compare it with your ISP and find out whether your VPN is leaking DNS.
DNS Speed Test
Benchmark public resolvers
Benchmark Cloudflare, Google, Quad9 and OpenDNS from your own connection and see which resolver answers fastest.
IP Lookup
Your IP, ISP and device
See your public IPv4 and IPv6 address, ISP, country, city, timezone, browser, operating system, screen and connection type.
SSL Checker
Certificate and TLS health
Check any domain's SSL certificate: issuer, expiry date, TLS version, security grade and hardening recommendations.
Uptime Checker
Is the site up right now?
Check whether a website is online from our network, with HTTP response code, response time and availability verdict.
