What each one is
Cortex
Cortex is a local AI engine with a simple CLI, an OpenAI-compatible API and multiple backends (llama.cpp, TensorRT-LLM), designed to power the Jan desktop app or run standalone.
- Multiple inference engines behind one CLI
- OpenAI-compatible server out of the box
- Backed by the team behind the Jan desktop app
RamaLama
RamaLama makes running local models boringly simple by treating models as OCI container images, reusing the container tooling you already have.
- Models are just container images
- Auto-detects GPU and picks the right runtime
- No Python dependency hell
Key differences
Cortex is local runtime (CLI), while RamaLama is container-native runtime. Their licenses differ (Apache-2.0 vs MIT), which matters if you ship a commercial product. Cortex leans more beginner-friendly, whereas RamaLama is more suited to intermediate users. In short, Cortex fits a clean Ollama alternative with swappable engines, and RamaLama fits teams that already live in Docker/Podman.
Which should you choose?
Choose Cortex for a clean Ollama alternative with swappable engines. Choose RamaLama for teams that already live in Docker/Podman.
There is rarely one winner — many setups use both. The right pick depends on your hardware, your team's skills, and whether you value simplicity or control.
