Your AS/400 wasn't built for AI. We make it AI-ready anyway.
Expose the RPG, COBOL, and DB2 logic locked inside your IBM i as governed APIs your modern apps and AI agents can actually use - without touching your source, and without a big-bang rewrite.
What's holding your IBM i back
Three reasons AS/400 modernization gets harder every yearYour RPG experts are retiring
The people who can read your RPG are retiring. The IBM i talent pool shrinks every year, and the business logic walks out the door with it. For the first time ever, IT leaders rank the IBM i skills gap as their #1 concern for the platform.
You can't point AI at a green screen
Interest in AI on IBM i jumped from 30% to 42% of shops in a single year. But without a governed API layer underneath, that appetite has nowhere to go — your most valuable business logic stays invisible to the agents and applications that need it.
Every day still starts with a 5250 emulator
Most IBM i work still runs through green-screen terminals and desktop emulators, on logic only one or two people in the building can actually read. Without a governed, browser-based alternative, that's the default - not the exception.
How OpenLegacy moves your
IBM i forward
Modernize your IBM i one business process at a time, with no big-bang risk and no wasted work
One platform,
end to end
Access, explore, expose, and modernize your AS/400 from a single platform — one thing to buy, secure, and govern, instead of a shelf of point tools from separate vendors.
Discover once,
reuse forever
We create an inventory and analyze your RPG, DSPF, and DB2 assets one time, so every future API, replatform, or reimagine builds on that same foundation instead of starting over.
Your path,
your order
Integrate, replatform, or reimagine — three real paths, not a mandatory sequence — so you start wherever the business need is and never waste discovery work.
