There is a GitHub organization called
Software KMS Activation. It hosts four repositories containing KMS tools: an activator for Windows 10/11, a beta version of KMS Auto, an Office activator, and a beta version of KMS Pico. The code is written in Python, Rust, and C, with updates dating back to late May 2026. If you are familiar with coding, you can examine the inner workings of KMS activation mechanisms. As always, use is at your own risk.
