Alpine Kindle Toolkit

Alpine Kindle lets you run Alpine Linux directly on your Kindle e-reader. This makes it possible to open a minimal version of Chromium and manage files as if you were on a Linux computer—right from your Kindle. However, this environment is extremely limited, slow, and only useful for basic experimentation.

Summary
Alpine Kindle gives you a true Linux shell on your Kindle, plus the rare ability to run a browser and explore file management from e-ink. While extremely limited, it’s a unique way to experiment with Linux on Kindle hardware.
