Introduction

Codee is a development tool that automatically scans Fortran, C, and C++ source code to provide actionable suggestions (referred to as “checks”) to help adhere to the recommendations documented in the Open Catalog of Best Practices for Correctness, Modernization, Security and Optimization. As of January 2025, this catalog includes more than 80 recommendations and continues to expand.

More specifically, Codee performs an static analysis of your code, checking every line against the recommendations of the Open Catalog to identify improvement opportunities without the need to run the code. Codee produces detailed reports tailored to different user profiles, providing insights into code health and actionable steps for correctness, modernization, security and optimization.

Additionally, Codee offers automatic formatting for Fortran source code, helping teams maintain a consistent code style across codebases.
