Hopper lets you use AI agents to work inside IBM mainframe (z/OS) environments from a modern desktop app.
Navigate TN3270 terminals and ISPF panels using AI agents instead of manual commands
Write and submit JCL jobs, then get plain-language diagnostics when they fail
Debug failed jobs by tagging them — the agent surfaces the error code, failing step, and source line
Query VSAM (mainframe file system) data using familiar SQL-style commands
Compile, test, and deploy COBOL programs to CICS in a single prompt

Hopper uses AI agents to navigate mainframe panels, write column-strict JCL, decode job failures into structured diagnostics, and operate z/OS environments autonomously with human approval checkpoints.
Hopper is built for businesses that already run IBM mainframe systems and want to speed up developer workflows — think large banks, insurers, or government contractors with legacy z/OS infrastructure. The free tier is genuinely useful and the AI-powered job debugging alone could save your team several hours per incident. That said, this tool is too specialized for most small businesses, and enterprise pricing is a black box — so budget carefully before committing your team.
AI-generated training guides tailored to your team's size, skill level, and focus areas for Hopper — coming in v0.3.2.
