Our verdict

LabEx teaches Linux, DevOps, cybersecurity, programming, and data science entirely through interactive labs and real projects, with no video lessons at all. An AI chatbot called Labby, built on ChatGPT, helps debug code and answer questions as you work through structured skill trees. It's aimed at people who learn by doing rather than watching, and some advanced certification tracks assume you already have basic command-line comfort.
