About Harbor
Harbor is a containerized CLI toolkit that brings a complete pre-wired LLM stack with hundreds of services to your local machine. It handles Docker Compose orchestration, configuration, and cross-service connectivity so you can run LLM backends like Ollama, llama.cpp, or vLLM alongside frontends like Open WebUI and supporting services like SearXNG, ComfyUI, and LangFuse — all with minimal configuration.
Pros & Cons
Pros
- Single command spins up an entire local AI development environment with dozens of pre-wired services
- Supports all major LLM inference engines and frontends with automatic cross-service connectivity
- Shared cache system prevents redundant downloads of large model files across services
- Completely free and open source under MIT license with active development
- Harbor Boost modules add middleware capabilities like caching, routing, and request modification
Key Features
One-Command Setup
Spin up a complete local LLM stack with a single harbor up command — backends, frontends, and services all pre-wired together
100+ Supported Services
Supports major inference engines (Ollama, llama.cpp, vLLM, TGI, LiteLLM, TabbyAPI, Aphrodite, SGLang) plus dozens of frontends and utilities
Pre-Configured Integrations
Services are automatically connected — running SearXNG enables Web RAG in Open WebUI, Speaches provides OpenAI-compatible STT and TTS out of the box
Harbor App UI
A companion desktop app providing a clean interface for managing services, configurations, and workflows
Harbor Boost
Modular enhancement system that adds capabilities like caching, routing, and middleware to your LLM stack
Harbor Bench
Built-in benchmarking tool for evaluating and comparing LLM performance across different backends and models
Shared Cache System
Host cache is shared and reused across services — Hugging Face models, Ollama weights, and other artifacts are downloaded once
