Hopper is the pioneering agentic development environment specifically engineered for the mainframe, serving as the "Cursor for mainframes." It seamlessly integrates a real TN3270 terminal with mainframe-aware panels for managing datasets, jobs, members, and spool output. At its core is an advanced AI agent capable of operating across complex z/OS workflows. This intelligent agent can inspect datasets, efficiently read and edit PDS members, accurately write JCL, submit jobs, parse intricate JES output, provide clear explanations for failures, and significantly assist developers in debugging mainframe workflows at an accelerated pace. Hopper is broadly accessible, available across Windows, Linux, and macOS platforms.
