Checkn1x is a minimalistic, command-line-only Linux distribution (based on Alpine Linux) that boots directly into a pre-configured environment for the checkm8 bootrom exploit. It was created by the developer to eliminate the headaches of setting up a proper Linux environment just to jailbreak.

For many iOS enthusiasts, the name is synonymous with freedom. However, because Checkra1n was built on the checkm8 exploit—a hardware-level vulnerability—it traditionally required a macOS or Linux environment to run. This left Windows users in the dark until Checkn1x arrived.
