Mainframe → AI, safely
Legacy to AI
one process at a time
Turn decades of legacy systems into the foundation enterprise AI needs — no disruption, no rewrites, no guesswork.
Start with your most complex system or go all the way to full modernization.
Trusted by teams modernizing the world's most critical systems
The OpenLegacy platform
-
OL HubGovern, deploy, and operate the OpenLegacy suite (SaaS or unified OnPrem) with shared identity, API keys, access control, AI, and MCP.
-
OL GeneRun natural-language agent workflows across APIs and MCP tools from one governed Co-pilot control plane.
-
OL CoreIQBrowse, test, and turn IBM Z and IBM i assets (VSAM, DB2, CICS, IMS, and IBM i programs) into secure REST APIs and change events from one browser workbench.
-
OL AtomIQDecompose a z/OS or IBM i monolith one piece at a time: analyze COBOL and RPG, find operations and domains, trace data lineage, and route cross-app calls as you decouple.
-
OL IntegrationTurn mainframe, IBM i, and on-prem programs, transactions, screens, and databases into tested APIs and events: connect, design contracts and flows, generate, deploy, and monitor without changing the host.
-
OL DataIQOne workspace for DB2, DB2 for i, IMS DB, Oracle, SQL Server, PostgreSQL, MySQL, and MongoDB: query with AI help, copy test data, migrate VSAM and IMS into SQL, and turn queries into APIs.
-
OL SpecGenerate specifications, documentation, and modernization blueprints from legacy systems with AI.
-
OL TermIQSee how 3270 and 5250 applications are really used: record sessions, catalog screens, identify and measure business operations, alert when activity matches a rule, and turn real journeys into terminal screens flows for APIs.
-
OL TerminalGive teams instant browser access to 3270 and 5250 terminal screens without desktop emulators, not map descriptors or remote BMS/MFS hosts.
-
OL NextMove COBOL and RPGLE screen and RPC programs (CICS/BMS, IMS/MFS, IBM i/DSPF) off the host as runnable code on the JVM, validate them in the browser, and expose them as REST APIs while data stays on the host.
-
OL CodeA browser IDE for COBOL and RPG on IBM Z and IBM i: browse, edit, compile, and test programs, convert screen programs into RPC services, and generate clients that call REST APIs.
-
OL AppIQBuild enterprise applications, integrations, workflows, and digital experiences with AI-assisted development on OpenLegacy assets.

01
Agentic Mainframe DevelopmentAn agentic, context-aware workspace for z/OS mainframe teams to understand, change, document, and API-enable COBOL, CICS, IMS, DB2, and VSAM applications with AI grounded in the real code base.
-

02
API IntegrationTurn mainframe and IBM i programs, screens, transactions, and data into governed APIs and events without rewriting the core.
-

03
AS/400 (IBM i) ModernizationOne path for IBM i shops: browser 5250 access, RPG and DSPF analysis, governed APIs, and RPGLE that runs off the host.
Global enterprises modernize critical systems faster
with no disruption.
Grupo Herdez exposed IBM i RPG, CL, and DB2 functions as cloud-native services and deployed them to Google Cloud Application Integration in one day.
Citi connected legacy host systems to modern cloud-based treasury and payment services without disruptive core changes.
Globe Life launched Customer Portal 2.0 with real-time mainframe connectivity from 3270 screens — on schedule, without refactoring z/OS and z/VSE cores.
