LlamaBarn

LlamaBarn is a tiny menu bar app that lets you install and run local LLMs with just a few clicks. It automatically configures each model to run optimally on your Mac, and exposes a standard API that any app can connect to.

Install with brew install --cask llamabarn or download from Releases ↗

How it works

LlamaBarn runs as a tiny menu bar app on your Mac.

• Install a model from the built-in catalog -- only models that can run on your Mac are shown
• Select an installed model to run it -- configures and starts a server at http://localhost:2276
• Use the running model via the API or web UI -- both at http://localhost:2276

Under the hood LlamaBarn uses llama.cpp and runs models with no external dependencies.

Use cases

Connect to any app that supports custom APIs:

• chat UIs like Chatbox or Open WebUI
• CLI assistants like OpenCode or Codex
• editors like VS Code or Zed
• editor extensions like Cline or Continue
• custom scripts using curl or libs like ai sdk

Or use the built-in web UI at http://localhost:2276 to chat with the running model directly.

Endpoints

LlamaBarn builds on the llama.cpp server and supports the same API endpoints:

# say "Hello" to the running model
curl http://localhost:2276/v1/chat/completions \
  -H "Content-Type: application/json" \
  -d '{"messages": [{"role": "user", "content": "Hello"}]}'
