What is Mainframe Application Development Software in China?
Mainframe application development software provides tools and environments for building, testing, deploying, and maintaining applications that run on mainframe systems. These platforms support programming languages commonly used in enterprise mainframes, such as COBOL, PL/I, Assembler, and Java, while enabling integration with modern development workflows. The software often includes debugging, code editing, workload management, source control, and automated testing capabilities to improve developer productivity and application reliability. Many solutions integrate with DevOps pipelines, cloud platforms, and API frameworks to help organizations modernize legacy systems and connect them with newer technologies. By supporting high-performance, large-scale transaction processing and mission-critical workloads, mainframe application development software remains essential for industries such as banking, insurance, government, and telecommunications.

AWS Transform
Amazon
AWS Transform is an agentic AI service from Amazon Web Services that automates and accelerates the modernization of legacy workloads, specifically .NET, mainframe, and VMware environments. Built on AWS’s migration and modernization experience, it deploys specialized AI agents to carry out tasks like assessment, code analysis, dependency mapping, refactoring, decomposition, validation, and planning, many of which run in parallel, to speed up large-scale transformations. Through a shared workspace and natural-language chat interface, cross-functional teams can collaborate, track progress, and manage modernization projects from end to end. AWS claims AWS Transform can make .NET apps port up to 4 times faster, greatly speed VMware configuration conversion, and compress mainframe migration timelines (years down to months), while also helping reduce legacy licensing, infrastructure cost, and ongoing maintenance expenses. -

Assembler Code Refactoring
Rocket Software
Rocket Assembler Code Refactoring is a specialized modernization solution that automatically restructures legacy Assembler code into structured pseudocode or modern languages such as COBOL, C, or Java without altering external behavior, enabling faster, lower-risk modernization and improved maintainability. Assembler code is notoriously dense, poorly documented, and supported by a shrinking pool of specialists, making maintenance slow, costly, and error-prone; this product addresses those challenges by delivering semantics-preserving, auditable transformations that reduce outages and secure modernization without sacrificing stability. Its fully automated core engine uses mathematically guaranteed logic equivalence to eliminate conversion risk, dramatically accelerating projects while ensuring that refactored outputs are semantically identical to the original code.
