Hands-on Linux, DevOps and cybersecurity labs in the browser
Beginner
What is LabEx?
LabEx is a courses tool. LabEx teaches Linux, DevOps, cybersecurity, programming and data science through interactive browser labs and structured skill trees, with AI chatbot assistance and lab environments aimed at ten Linux and DevOps certifications including RHCSA, CKA and CompTIA.
LabEx is a browser-based training platform built around doing rather than watching. Instead of recorded lectures, learners work inside live online environments: a Linux terminal, container labs, cloud consoles and security sandboxes that run directly in the browser with nothing to install. The catalog spans Linux, DevOps, cybersecurity, programming, data science and AWS, with more than 6000 hands-on labs and over 2000 skills listed on the homepage. The structure is what separates LabEx from a pile of loose exercises. Each topic is organised as a skill tree, a graded path where one lab unlocks the next, so a beginner can move from basic shell commands to running containers without guessing what to study next. Alongside the trees sit real-world projects that consolidate several skills at once. An AI chatbot called Labby, powered by ChatGPT, sits inside the labs to explain errors, debug commands and answer technical questions in context, which partially replaces the human mentor a self-taught learner usually lacks. Certification candidates are a clear target audience. LabEx advertises lab environments mapped to ten Linux and DevOps exams: RHCSA and RHCE on RHEL, CompTIA Linux+, A+, Network+ and Security+, the Kubernetes trio CKA, CKAD and CKS, and LFCS. The Linux Journey material, formerly linuxjourney.com, remains free and open source, hosted on GitHub, and needs no account, which makes it a reasonable entry point before committing to a structured path. Against alternatives, LabEx leans on practice volume and certification alignment rather than video libraries or instructor-led cohorts. Learners who need a syllabus, exam-shaped environments and instant AI feedback will find the fit natural. Those who prefer a comprehensive video course or formal classroom instruction should treat it as a supplement. The homepage reports more than 1.2 million learners.
How do you use LabEx?
1Create a free account
Sign up on the registration page to unlock the labs and keep progress across skill trees. Free access is advertised as the starting point for new learners.
2Pick a skill tree
Browse the learning catalogue and choose a track such as Linux, DevOps, cybersecurity or AWS. Each tree sequences labs from introductory to advanced.
3Open the browser Linux terminal
Try the online Linux terminal playground to get comfortable with the environment before starting graded labs. Nothing is downloaded or installed.
4Work through the Linux labs
Follow the Linux path lab by lab, using Labby to explain errors and debug commands when a step fails. Completing a lab unlocks the next one in the tree.
5Target a certification track
If an exam is the goal, switch to the matching path, for example RHCSA for RHEL administration or CKA for Kubernetes, and practise against objectives.6Consolidate with a project
Finish by building a real-world project that combines the skills learned, which the platform positions as the step from exercises to applied work.
Pros and cons
Pros
- Live browser environments remove local setup friction for Linux, DevOps and security practiceAI
- Structured skill trees give a clear order of study instead of a flat catalogue of exercisesAI
- Lab content is mapped to ten named Linux and DevOps certifications, including RHCSA, CKA, CKAD and CKSAI
- Labby, the ChatGPT-powered assistant, answers questions and helps debug commands inside the labAI
- Linux Journey remains free, open source and usable without an accountAI
Cons
- Pricing tiers and plan limits are not disclosed on the homepage, so cost has to be checked separatelyAI
- The AI helper is a general model rather than a verified instructor, and its debugging advice can be wrongAI
- Certification alignment is claimed but no exam pass rates or independent outcomes are publishedAI
- Depth outside the Linux, DevOps and cloud tracks is less evident from the homepageAI
- No video instruction at all, which will not suit learners who prefer explanation before practiceAI
