Quick Browser Internet Speed Test
Use this to compare connections or spot an obviously slow path without running a large bandwidth benchmark.

DeviceOK measures browser-visible connection hints and HTTP round trips to DeviceOK. Throughput samples use small HTTP transfers to DeviceOK and are useful for quick comparison, not ISP speed certification. This is not an ICMP ping, local-network scan, or VoIP/RTP jitter measurement. A public IP can represent a VPN, carrier gateway, proxy, or shared NAT rather than a physical device address.
The test transfers small random byte samples to and from DeviceOK; it does not scan your local network.
Use the result as evidence, not a guess.
- Small HTTP download throughput sample
- Small HTTP upload throughput sample
Short tests can understate very fast links because latency and browser overhead matter more.
Use your ISP or a dedicated multi-server speed service for certified or comprehensive testing.
