About MeterX
One person built MeterX to answer a plain question honestly: is the connection I pay for the connection I get?
How it measures
A twenty second test in four phases, with latency measured under load. The details are on How it works.
Open source
The extension, the worker and the self-hosted server are open source under AGPL-3.0 at github.com/ajithakdev/meterx. Bug reports and ideas go in the issues there.
Who made it
Ajith Kumar K, a backend engineer. More of his work is at ajithakdev.com.
