Hopper
Modernize mainframe COBOL development with AI-powered agentic tools.
Quick verdict
Hopper is an AI-powered agentic development environment built specifically for mainframe and COBOL codebases, designed to help enterprise teams modernize legacy systems faster and with greater confidence. It is aimed at software engineers, modernization teams, and enterprises that manage large COBOL workloads and need intelligent tooling to navigate complex, decades-old code. Hopper brings agentic AI capabilities into the mainframe space, an area traditionally overlooked by modern developer tools, enabling developers to understand, refactor, and extend COBOL applications without requiring deep institutional knowledge. The platform acts as an intelligent co-pilot that can reason about legacy code structures, surface documentation, suggest improvements, and automate repetitive transformation tasks. This makes Hopper especially valuable for organizations facing a shortage of COBOL expertise or looking to gradually migrate workloads to modern architectures without a full rewrite.

Frequently asked questions
Is Hopper free?
Hopper offers a free tier with limited access for individual developers. Full capabilities, especially for enterprise or team use, likely require a paid plan or direct contact with the Hypercubic AI team.
What is Hopper best used for?
Hopper is best used for understanding, documenting, and refactoring legacy COBOL code on mainframe systems. It is particularly valuable for enterprises looking to modernize old applications, onboard new developers to complex codebases, or gradually migrate workloads to modern platforms.
What are the best alternatives to Hopper?
Alternatives include IBM watsonx Code Assistant for Z, Broadcom Compuware tools, and general-purpose AI coding assistants like GitHub Copilot or Amazon CodeWhisperer, though none of these are as specifically focused on agentic COBOL development as Hopper.
Is Hopper safe to use?
Hopper is developed by Hypercubic AI and is designed for enterprise environments. As with any AI tool handling proprietary code, organizations should review the platform's data handling and security policies before integrating it into production mainframe workflows.
How much does Hopper cost?
Hopper's exact pricing is not fully listed publicly. There appears to be a free entry point for individual developers, with paid or enterprise plans available on request. It is recommended to contact Hypercubic AI directly for detailed pricing information.
