Who builds KEIBIDROP, and how to check the claims on this site.
KEIBIDROP is built by KEIBISOFT S.R.L., a company registered in Romania and trading since 2023. The core is open source and the repository is public, so the code behind every claim on this site can be read. Two part-time engineers work on it, funded by consulting work rather than outside investment. Both are named below.
Security and systems engineer. Held the top security role at three B2B SaaS companies since 2019, two of which were acquired. Sets the engineering direction for KEIBIDROP, runs the experiments and the measurements, and owns the architecture and the release standard.

Three things make the claims checkable without taking anyone's word for it.
The core is open source at github.com/KeibiSoft/KeibiDrop, including the test suite. There is more test code than product code.
Throughput depends on the link, the round trip time, the processor, and the file size. Any figure on this site names the conditions it was measured under, because a number without them cannot be checked.
Each page that makes a claim also states where the approach does not apply. The engineering write-ups on the KeibiSoft blog include the failures and the measurements that did not go our way.
