A running system, end to end

Every capability is proven by battle suites running real, unmodified open-source RPG and DDS — and every deviation from the real machine is documented, never silently approximated.

Proven on real code

No synthetic demos — the test corpus is real, public RPG written for real machines, run verbatim.

One published price list. Same as SteelFrame.

Hosted midrange LPARs run $700–$1,500 a month, and everyone else in this market hides their price behind a sales call. A dedicated MidFrame company environment is $199 a month — published, here.

A dedicated environment for every company

The demo you just launched IS one — a private environment, provisioned in about a second. Company environments add persistence, your own estate, own users, and backups — isolated from everyone else's.

Modernizing a mainframe estate too? MidFrame's sibling SteelFrame does the same for z/OS-class workloads — same pricing, same platform.

Your midrange system is one click away.

One click provisions your own private environment — then talk to us about a dedicated one for your estate.
