IBM i automation & API-driven RPG development
From Swagger to RPG and back — safely, at scale
CoreStratos helps IBM i teams automate RPG development and API documentation. Generate Swagger/OpenAPI from existing RPG and COBOL programs, create production-ready RPG skeletons from Swagger and keep specifications and code aligned, without disrupting your current workflow.

Why CoreStratos?
An independent IBM i-focused initiative that helps you automate, standardize and document API-based RPG developments without rewriting your entire codebase.
API documentation from existing code
Parse existing RPG and COBOL programs, extract endpoints and configuration, and generate Swagger/OpenAPI definitions that can be shared with integration partners or front-end teams.
Modern developer experience
Use the RPGTools VS Code extension to browse RPG sources, trigger Swagger generation, generate skeletons from templates and keep documentation aligned with your source code.
Powered by RPGTools Suite
