The definitive pre-processing engine
Palm Key
Understand everything. Change anything.
The definitive pre-processing engine for legacy systems. Dependencies, JCL, data flow, and CRUD — every hidden connection, mapped before a single line changes.
You can't safely change what you can't see. Palm Key reveals every connection in your codebase — before anything is touched.
The unlock
Forty years, locked in a box.
Key opens it into a blueprint.
life with key · three mornings
“nobody knows what touches acct-mstr”
You ask.
The estate answers.
Programs, copybooks, JCL, data flow, CRUD — the web no one person still holds in their head becomes a map anyone on your team can query. The morning Key finishes, “who touches this file” is a lookup, not a legend.
“change freeze — impact unknown”
Change stops
being frightening.
Every hidden connection is visible before a single line moves. Impact analysis that took a six-week study happens before the stand-up ends — so your people change the system instead of tiptoeing around it.
“modernize all 12,000 programs”
A third of the work
disappears.
The dead-code report finds what nothing calls and nobody uses — typically 33–40% of the estate — and removes it from scope before the program is even priced.
the day after
What quietly changes.
More inside
A complete picture, without the noise.
Instantly structure your entire codebase into something a team can navigate.
Bring meaning to complex data structures and the flows that touch them.
Know exactly what changes between versions — and what stays the same.
A single, complete picture of your system, free of the noise.
One waveform. Four frequencies.
Key is where every engagement begins — the map that Ark and Ray are built on.
