Why build this now

The most-used language on Earth's most-overlooked platform deserves better tools.

RPG and ILE COBOL developers have been working in tools that haven't materially changed in a decade. SEU was last meaningfully updated in the 1990s. RDi, while modern, is heavy, expensive, and tied to a shrinking platform. Meanwhile, the wider development world standardized on VS Code. Infinite Studio brings that world to IBM i developers.

Modern editing

Syntax highlighting, IntelliSense, code folding, multi-cursor, and refactoring for RPG Free, ILE COBOL, CL, and DDS.

Real version control

Native Git integration. Branch, diff, commit, and pull request your RPG source like any modern codebase.

AI that knows RPG

Inline AI suggestions trained on RPG and COBOL idioms — explain legacy code, generate tests, suggest fixes.

Private beta · Q3 2026

Help shape the IDE your team has always wanted.

We're inviting a small group of RPG and ILE COBOL shops into the Infinite Studio private beta. Tell us about your codebase and your current toolchain, and we'll be in touch.

The Infinite i platform and its add-ons

Infinite i at the core — with add-ons for the interface, data, and developer experience.

Infinite i

Core Platform

The core platform — recompile RPG, COBOL, CL, and DDS to native Linux on AWS, Azure, or GCP. 45–60 days. Half the cost of staying on Power.
