Cortex is a web application framework designed to feel familiar if you’ve used Ruby on Rails, but implemented in C and oriented toward AI-native workflows.

It embraces the “Rails Way”: convention over configuration, a clear project structure, and an emphasis on developer happiness. If you already know how a Rails app is organized, you’ll feel at home. The difference is under the hood: Cortex is written in C, giving you low-level control, a small footprint, and excellent performance.

Cortex is open source and just getting started. Whether you’re a C veteran, a Rails developer curious about systems programming, or someone passionate about AI tooling, there’s a place for you here.
