Network measurement instrument
See exactly where your connection degrades.
One button runs a full pass — download, upload, latency under load, packet loss, and a hop-by-hop trace of the route — so you can see whether the problem is your Wi‑Fi, your ISP, or somewhere else.

Path trace detail
per-hop RTT toward you
Each hop is a router your traffic crosses on its way to the server — first your own gear, then your ISP, then the internet backbone. 12 or more is normal. The Zone column shows whose network a hop sits in, and the hostname usually names the operator (e.g. comcast.net, cloudflare.com).
How it works: Speedbug runs latency, download, upload, bufferbloat and a hop-by-hop path trace from your browser against a dedicated server, then translates the raw numbers into plain language. Read the full methodology →
