For education
Teach mainframe without running one.
A safe, browser-based z/OS lab for universities and apprenticeship providers. No lab to provision, no access to request. Just a browser and a class, on laptops or iPads.


9 role-based tracks and 228 lessons, from a first command through JCL, COBOL, DB2, CICS, RACF and REXX. See the curriculum
Live in days, not quarters
Your class could be up and running within days.
Nothing to install, nothing to provision, no infrastructure to stand up. The day your class has access is the day they start learning.
Access is the reason most courses never start.
Teaching mainframe has always meant securing hardware, credentials, and support that most institutions cannot justify. Mainframe101 removes that barrier so the teaching can actually happen.
Everything a course needs, in a browser tab.
No lab to provision, no credentials to chase. Just a browser and a class.
Zero infrastructure
Nothing to install, provision, or maintain. The access blocker that stops most mainframe teaching is simply gone.
Structured tracks
Guided paths that map to real outcomes, from fundamentals through JCL, COBOL, DB2, and CICS.
One tutor, many students
Zed guides each learner step by step, so a single tutor can support a whole class.
Credentials they keep
Students earn OpenBadge credentials and certificates they can show to employers.
