LabEx
LabEx is a hands-on learning platform offering free interactive labs for Linux, DevOps, Cybersecurity, Programming, and Data Science. Learners practice in real online environments instead of watching videos, guided by structured skill trees, real-world projects, and Labby, an AI assistant powered by ChatGPT. Trusted by over one million learners, it also covers certification prep for Red Hat, CompTIA, CNCF, and the Linux Foundation.
What is LabEx?
LabEx is an online hands-on learning platform for technology skills, built around interactive labs that run in real online environments. Instead of passive video courses, learners get a live Linux terminal, Docker container, or Kubernetes cluster in the browser and complete guided tasks step by step. The platform organizes content into structured skill trees, which are visual learning paths across Linux, DevOps, Cybersecurity, Programming, and Data Science, where each node is a lab that unlocks the next. Learners progress through three simple steps: choose a skill tree, learn a skill, and build a project. Key capabilities include hands-on online environments such as an online Linux terminal, Kali Linux, Ubuntu terminal, Python interpreter, and Docker, Kubernetes, Golang, C++, Java, Rust, Ansible, and Jenkins playgrounds; AI-powered assistance through Labby, a ChatGPT-powered chatbot that helps debug code and answers technical questions; over 6,000 hands-on labs, 2,000+ skills, 400+ real-world projects, and 2,000+ challenge solutions; certification preparation for Red Hat (RHCSA, RHCE), CompTIA, Kubernetes/CNCF (CKA, CKAD, CKS), and Linux Foundation (LFCS) with labs mapped to exam objectives; Linux Journey by LabEx, a free, open-source Linux course formerly known as linuxjourney.com, hosted on GitHub and continuously improved by the community; practice labs, cheat sheets, tutorials, and interview question banks spanning Linux, Docker, Kubernetes, Python, Java, Git, Ansible, MySQL, and more; and a thriving community of over one million learners, with reviews, skill tracking, and live learner feedback. Beyond labs, the platform includes a challenges section, a reviews wall described as trusted and loved by learners for 8+ years, cheat sheets, tutorials, practice exercises, an RHCSA exam simulator, and interview question banks, while learners can track progress and follow popular paths such as the Linux skill tree with 600K+ learners. The platform is free to start with no credit card required, while Pro plans add unlimited virtual machines, full Labby access, certificates of completion, and access to all projects and solutions.

Who is LabEx for?
LabEx is built for anyone who wants to learn technology by doing rather than watching, and the site has been trusted by learners for 9+ years with 900,000+ active users. Its largest audience is computer science students, who praise the structured, game-like skill trees for turning abstract textbook concepts into real coding and Linux experience. Software developers and DevOps engineers use LabEx to practice Docker, Kubernetes, CI/CD, Ansible, Git, and related tooling in live environments before applying those skills at work. Cybersecurity newcomers explore Kali Linux, Nmap, Wireshark, and other security tools safely in online playgrounds without setting up their own machines. Certification candidates form a major audience: LabEx provides real lab environments mapped to exam objectives for RHCSA, RHCE, CompTIA (Linux+, A+, Network+, Security+), CKA, CKAD, CKS, and LFCS. Career changers and self-taught learners follow the structured skill-tree paths and build portfolios of real-world projects to show employers. Job seekers preparing for technical interviews work through challenges, practice exercises, and interview question banks. Teams and organizations can adopt LabEx Teams for structured employee upskilling.
