Which ISP is best for gaming? Real measurements from LagScope users — anonymized latency, jitter and packet-loss stats aggregated by ISP and country. Speed tests rank ISPs by bandwidth; this leaderboard ranks them by what actually matters in a match: a steady connection with low jitter, no packet loss and few lagspikes.
How it works: LagScope is a free in-browser internet-stability monitor. Users can opt in to contribute anonymous stats — only their ISP name, country and connection metrics (baseline latency, jitter, packet loss, lagspikes per hour, gaming-readiness score) are sent. No IP addresses are stored, there are no accounts, no cookies and no tracking. Reports are aggregated over a rolling 7-day window and grouped by ISP and country.

The ISP at the top of this leaderboard — ranked by average gaming-readiness score from real, anonymized LagScope measurements: latency, jitter, packet loss and lagspikes per hour, aggregated by ISP and country. Rankings update continuously as users run the monitor.
Each contributing session produces a gaming-readiness score from 0 to 100. Sessions start at 100 and lose points for jitter above what games can absorb, packet loss, a spiky latency tail (high p99 vs median), recent lagspikes weighted by severity and recency, and outages. The leaderboard shows the average score across an ISP's sessions, alongside median baseline latency, average jitter, average packet loss and average lagspikes per hour.
Yes. Reporting is strictly opt-in (off by default — enable it in the monitor's Settings under “Contribute anonymous stats”) and each report contains only your ISP name, country, city, connection metrics and browser user-agent. No IP address is ever sent or stored, there are no cookies and no user accounts — measurements cannot be tied back to an individual.
