Show HN: Agentic interface for mainframes and COBOL

Hypercubic launches Hopper, an agentic development environment for mainframes that enables AI agents to autonomously operate TN3270 terminals, datasets, jobs, and other z/OS surfaces. It targets COBOL and mainframe systems still critical to banking, insurance, and other infrastructure, automating repetitive debugging and development tasks.

Key points

  • Hopper combines a real TN3270 terminal, mainframe-aware panels, and an AI agent to operate autonomously in z/OS environments.
  • Designed for COBOL systems running on mainframes, which still handle critical transactions in banking, payments, insurance, and more.
  • Sensitive operations require approval, and the terminal remains visible at all times for safety and control.
