llamactl

Unified management and routing for llama.cpp, MLX and vLLM models with web dashboard.

Features

🚀 Easy Model Management

• Multiple Models Simultaneously: Run different models at the same time (7B for speed, 70B for quality)
• Smart Resource Management: Automatic idle timeout, LRU eviction, and configurable instance limits
• Web Dashboard: Modern React UI for managing instances, monitoring health, and viewing logs

🔗 Flexible Integration

• OpenAI API Compatible: Drop-in replacement - route requests to different models by instance name
• Multi-Backend Support: Native support for llama.cpp, MLX (Apple Silicon optimized), and vLLM
• Docker Ready: Run backends in containers with full GPU support

🌐 Distributed Deployment

• Remote Instances: Deploy instances on remote hosts
• Central Management: Manage everything from a single dashboard with automatic routing

Quick Start

1. Install a backend (llama.cpp, MLX, or vLLM) - see Prerequisites below
2. Download llamactl for your platform
3. Run llamactl and open http://localhost:8080
4. Create an instance and start inferencing!

Prerequisites

Backend Dependencies

For llama.cpp backend: You need llama-server from llama.cpp installed:

# Homebrew (macOS)
brew install llama.cpp

# Or build from source - see llama.cpp docs
# Or use Docker - no local installation required

For MLX backend (macOS only): You need MLX-LM installed:

# Install via pip (requires Python 3.8+)
pip install mlx-lm

# Or in a virtual environment (recommended)
python -m venv mlx-env
source mlx-env/bin/activate
pip install mlx-lm

For vLLM backend: You need vLLM installed:

# Install via pip (requires Python 3.8+, GPU required)
pip install vllm

# Or in a virtual environment (recommended)
python -m venv vllm-env
source vllm-env/bin/activate
pip install vllm

# Or use Docker - no local installation required

Docker Support

llamactl can run backends in Docker containers, eliminating the need for local backend installation:

backends:
  llama-cpp:
    docker:
      enabled: true
  vllm:
    docker:
      enabled: true

Installation

Option 1: Download Binary (Recommended)

# Linux/macOS - Get latest version and download
LATEST_VERSION=$(curl -s https://api.github.com/repos/lordmathis/llamactl/releases/latest | grep '"tag_name":' | sed -E 's/.*"([^"]+)".*/\1/')
curl -L https://github.com/lordmathis/llamactl/releases/download/${LATEST_VERSION}/llamactl-${LATEST_VERSION}-$(uname -s | tr '[:upper:]' '[:lower:]')-$(uname -m).tar.gz | tar -xz
sudo mv llamactl /usr/local/bin/

# Or download manually from the releases page:
# https://github.com/lordmathis/llamactl/releases/latest

# Windows - Download from releases page

Option 2: Docker (No local backend installation required)

# Clone repository and build Docker images
git clone https://github.com/lordmathis/llamactl.git
cd llamactl
mkdir -p data/llamacpp data/vllm models

# Build and start llamactl with llama.cpp CUDA backend
docker-compose -f docker/docker-compose.yml up llamactl-llamacpp -d

# Build and start llamactl with vLLM CUDA backend
docker-compose -f docker/docker-compose.yml up llamactl-vllm -d

# Build from source using multi-stage build
docker build -f docker/Dockerfile.source -t llamactl:source .

Note: Dockerfiles are configured for CUDA. Adapt base images for other platforms (CPU, ROCm, etc.).

Option 3: Build from Source

Requires Go 1.24+ and Node.js 22+

git clone https://github.com/lordmathis/llamactl.git
cd llamactl
cd webui && npm ci && npm run build && cd ..
go build -o llamactl ./cmd/server

Usage

1. Open http://localhost:8080
2. Click "Create Instance"
3. Choose backend type (llama.cpp, MLX, or vLLM)
4. Configure your model and options (ports and API keys are auto-assigned)
5. Start the instance and use it with any OpenAI-compatible client

Configuration

llamactl works out of the box with sensible defaults.

server:
  host: "0.0.0.0"                # Server host to bind to
  port: 8080                     # Server port to bind to
  allowed_origins: ["*"]         # Allowed CORS origins (default: all)
  allowed_headers: ["*"]         # Allowed CORS headers (default: all)
  enable_swagger: false          # Enable Swagger UI for API docs

backends:
  llama-cpp:
    command: "llama-server"
    args: []
    environment: {}               # Environment variables for the backend process
    docker:
      enabled: false
      image: "ghcr.io/ggml-org/llama.cpp:server"
      args: ["run", "--rm", "--network", "host", "--gpus", "all", "-v", "~/.local/share/llamactl/llama.cpp:/root/.cache/llama.cpp"]
      environment: {}             # Environment variables for the container

  vllm:
    command: "vllm"
    args: ["serve"]
    environment: {}               # Environment variables for the backend process
    docker:
      enabled: false
      image: "vllm/vllm-openai:latest"
      args: ["run", "--rm", "--network", "host", "--gpus", "all", "--shm-size", "1g", "-v", "~/.local/share/llamactl/huggingface:/root/.cache/huggingface"]
