## LabEx.io

LabEx takes a "no videos, 100% hands-on" approach to technology education. Courses are organized as skill trees, so instead of jumping between disconnected tutorials you follow a structured path covering Linux, DevOps, cybersecurity, Python, Java, data science, and more. Every step ends with a lab that runs in a real online terminal or cloud virtual machine, giving you the closest thing to production practice without setting up your own server.

The platform pairs those labs with an AI assistant called Labby, powered by ChatGPT, which acts as an always-available tutor for debugging and concept explanations. A large portion of the catalog is free forever, and LabEx also hosts the open-source Linux Journey material for learners just getting started with Linux.

With over a million learners, thousands of skills, and hundreds of hands-on labs, LabEx is aimed at students, career changers, and working engineers who want practical, verifiable skills and certification-oriented practice rather than passive video content.

**Pricing & Plans:** Freemium. A large catalog of labs is free, with no sign-up required for many of them, and the open-source Linux Journey content is always free. Paid plans (with a Pro subscription) unlock the full skill-tree library and premium features. Exact prices are listed on the LabEx pricing page.

- **Skill trees with guided paths:** Choose a structured path — Linux, DevOps, cybersecurity, Python, Docker, Kubernetes and more — and progress lab by lab from fundamentals to advanced topics.
- **Browser-based hands-on labs:** Practice inside real online terminals, pre-configured environments, and cloud virtual machines rather than reading passive tutorials.
- **Labby AI assistant:** An AI chatbot powered by ChatGPT that answers technical questions, explains concepts, and helps debug your code while you learn.
- **Real-world projects:** Apply each skill by building real projects, from containerized apps to automation scripts, that reinforce what you have learned.
- **Certification prep:** Comprehensive practice environments aligned with RHCSA, RHCE, CompTIA, CKA, CKAD, CKS, and LFCS exam objectives.

**Strengths:** Genuinely interactive — you learn by typing commands and building things; Free tier is substantial, including open-source Linux Journey material; Structured skill trees make long learning paths manageable; Labby AI assistant gives instant help when you get stuck

**Limitations:** No live human instructor; learners who need in-person mentorship may find the AI chatbot insufficient; Browser-based labs depend on a stable internet connection; Advanced or niche enterprise topics are not covered as deeply as general Linux and DevOps skills

## Ref Hub

Ref Hub — now published under the brand Righteo — is a recruitment software platform focused on automating the tedious parts of reference checking. Rather than having a hiring manager phone or email each referee and loosely summarise the conversation, the platform sends structured questionnaires that candidates and referees complete online, then consolidates the responses into consistent, comparable reports.

Alongside reference checks, the platform offers skills and competency assessments, letting employers verify practical, role-relevant ability early in the funnel. Combined, these two data streams give recruiters a firmer evidence base than a CV and a gut feeling, and they help flag low-quality, inconsistent or possibly fraudulent references before an offer is made.

The product targets HR teams, in-house recruiters and staffing agencies that process volume hiring and want to standardise how references and screening evidence are gathered. The refhub.com.au domain now redirects to righteo.com.au, so the site remains live under its current brand; plan specifics sit behind a free-trial and paid model, so it is worth confirming current tiers directly on the pricing page.

**Pricing & Plans:** Listed as free trial plus paid plans, with much of the detail provided through a sales demo. Check the current Righteo pricing page for exact tiers, since plan details are not fully public.

- **Automated Reference Checking:** Collect and summarise candidate references through a structured, automated workflow instead of manual calls and emails.
- **Skills & Competency Assessments:** Run role-relevant skills and competency assessments so hiring teams can verify practical ability, not just claims on a CV.
- **Fraud & Quality Signals:** Structured questionnaires and consistency checks help surface suspicious or low-quality references and reduce hiring risk.
- **Data-Driven Hiring Reports:** Turn raw referee responses into clear, comparable reports that give hiring managers evidence for decisions.
- **Candidate & Referee Workflows:** Automate reminder and follow-up sequences so references arrive faster and recruiters spend less time chasing.

**Strengths:** Automates a slow, manual recruiting process; Combines reference checks with skills assessments in one workflow; Structured reports make candidate comparisons easier; Helps catch poor-quality or fraudulent references

**Limitations:** Public plan details are thin and much of the experience is demo-led; Reference-check and assessment results still need human judgement before hiring decisions; Rebranding from Ref Hub to Righteo may leave older documentation and links stale
