HyperLoop
HyperLoop is a high-velocity mainframe modernization engine.
It rearchitects legacy mainframe applications into cloud-native runtimes. By using mathematical techniques to ensure high-precision, HyperLoop provides provable verifiability while compressing transformation timelines by 80%+.

Provable Safety
Every program in scope is modeled, safety-checked, and tracked. No statistical sampling, no skipped modules.
Machine-checked safety
Each program is modeled in Dafny and machine-checked for memory safety, type correctness, and runtime errors. No proof, no ship.
Decision-branch coverage
Coverage tracked at the decision-branch level, including branches proven unreachable. No dead logic carried forward.
Portfolio in one frame
Every program across CICS, batch, IMS, and assembler. Status, coverage, and ETA in one view.
Auditable Provenance
Every business rule extracted and linked to the COBOL paragraphs that produced it. No tribal knowledge lost in translation.
Rule extraction
Every business rule captured explicitly, classified by type, and tied to its source paragraphs.
Source-to-rule provenance
Each rule traces back to specific COBOL paragraphs and decision branches. Click for source, confirming conjectures, and modernization notes.
Rule-to-modern translation
Each rule lands on specific behavior in the modern build, with notes on what was preserved, simplified, or rebuilt.
Verified Cutover
Two gates before cutover. The modern build is replayed first against an isomorphic mainframe simulation, then against live mainframe traffic. No production cutover until both gates hold.
Closed-loop validation
The modern build runs against an isomorphic mainframe simulation, a deterministic reference that's known correct. Every divergence is a real bug with concrete input data. No flaky tests, no coverage gaps.
Rapid iteration
Each cycle replays tens of thousands of comparisons in a few minutes, not days. Every divergence comes with the input that triggered it, so a fix can be reproduced locally and verified in the next cycle.
Live triage
Every divergence is tracked through its lifecycle: open, investigating, patched, verified. The list updates as cycles complete, so you see exactly what's blocking the gate and what's already been fixed.
Modernizes you to the cloud you already use.
