Kali Linux is a Debian-based distribution designed for digital forensics and penetration testing. Developed by Offensive Security, it comes with numerous tools that are used by security professionals around the world. Kali Linux is not just about having a suite of tools; it's about having a platform that can adapt to a variety of security tasks.

Kali Linux is tailored for security experts, ethical hackers, and penetration testers.

Ubuntu, on the other hand, is a user-friendly Linux distribution that is based on Debian as well. It’s known for its simplicity and ease of use, which makes it a popular choice for both new and experienced users. Ubuntu aims to provide a free and open-source OS that anyone can use without much hassle.
